You mean you’re not going to pull the transmission you have so you can fix ONLY the reverse, and perhaps do an external reseal?To my mind, unless you own a low mileage garage queen that you intend to sell at some point for a speculative profit, I don’t see why it wouldn’t be the easiest/cleanest/qualitatively superior route to just get a remanufactured transmission from MB and be done with it. Yeah, numbers won’t match anymore, but that only comes into play if you have and plan to sell a low mileage unicorn. And even under that scenario, if I were in the market for a 500E, I’d prefer the car that has receipts for a MB remanufactured transmission vs. a third party rebuilt.
My car has 101k miles on it and a 2 sec delay when reversing- had that since I bought it at 87k miles. This delay has been increasingly bugging me and once it gets too much, I plan to buy the remanufactured transmission from MB and be done with it without any “matching number concerns” whatsoever.

I’m a big believer in the “while in there” approach that you also advocate with your cars. Especially since someone else is working on my car, I believe it’s the most economical way in the long run, as remove and replace in the same area ads up dramatically over time. Learned that the hard way with my door cards where I first replaced the interior armrests, then decided to replace the door pockets and then the door inserts.......piecemealed out because of the good old NLA situation. Should have just waited until I collect ALL the parts and then do one remove and replace session. Never again shall my impatience get the better of me on this car. So yeah, in my book, new gearbox and done. Might be a different story for those who can and want to do all their own wrenching and for those who only intend to keep their cars for a couple of years.You mean you’re not going to pull the transmission you have so you can fix ONLY the reverse, and perhaps do an external reseal?
As was said by JC and liviu, hundreds of dollars cost vs. thousands of dollars.
I personally think you are smart to get a factory reman. It’s more than double the $2K cost of a Sun Valley unit, but no question the rebuild will be better. And MB will have a two year warranty.
Have you looked into pricing for a MB remanufactured one?
That price doesn't seem unreasonable at all. A few years ago I had my sport beetle's manual gearbox rebuilt by a place that specializes in sport-beetle gearboxes. I had all the gears replaced with new non-OE gears and stainless steel synchros installed. The price of rebuilding my transmission was $13,600..... which was considered a fair price at the time. This price does not include the cost of removing the trans from the car.Roughly $4,200 plus a $1,200 core charge (the latter is refundable). Add another $1k for removal and install.
Can I get hired to carry your briefcase for you? My palms don't sweat...The price of rebuilding my transmission was $13,600
Knowing what I know now and having the experience that I've had, that's what would of I could go back in timeI don’t see why it wouldn’t be the easiest/cleanest/qualitatively superior route to just get a remanufactured transmission from MB and be done with it.
You are taking my words and twisting them (surprise!)You mean you’re not going to pull the transmission you have so you can fix ONLY the reverse, and perhaps do an external reseal?

That’s all for the birds. When I grow up, I want to have a NOS seat cushion and some NEEZ wheelsBut still it is nothing for someone like @TimL...... this is someone who is gambling on steering gear boxes and collecting back glass for fun!!!![]()
Exactly I think only a new 722.3 MB transmission is the only way forward here and not remans. (MB or otherwise)So yeah, in my book, new gearbox and done.
P.P.S. One thing that I have seen, with the rebuilders, particularly with Sun Valley and markedly less so with Peter Schmid, is that they will take the transmission back and either try to fix it, or will ship out another one to replace a faulty rebuild. I've heard some horror stories about Schmid honoring a "warranty" and wanting to take a defective rebuilt box back. I've seen a number of cases where Sun Valley shipped out a replacement box that same day when a rebuilt box was not working correctly.
Hmmm. Interesting that some members appear wholly comfortable with the idea of not keeping the original transmission numbers matching.To my mind, unless you own a low mileage garage queen that you intend to sell at some point for a speculative profit, I don’t see why it wouldn’t be the easiest/cleanest/qualitatively superior route to just get a remanufactured transmission from MB and be done with it.

You didn't see myYou are taking my words and twisting them (surprise!)
When I say that It goes without saying FULL tear down, inspection and re-seal throughout the transmission. I didn't think I had to explicitly state that too but there you go. Fact is from hands on experience it's usually only reverse that requires replacement everything else will normally be in factory spec.
As you guys have already stumbled through the realisation - rebuilders DO NOT fit all new parts. And since they handle many transmissons each day do you think they care about yours? Nope. I care about mine and nothing is rushed. By doing this work myself I can control and know EXACTLY what was done inside. Nothing wrong with that but apparently it stokes ridicule on here from people who never rebuilt a trans.....
The @gsxr, in particular, is waiting for that HOW-TO with bated breath!I did mention liviu's time frame, which he said was six weeks. It's very likely that for me personally, six weeks is an under-estimation of the amount of time it would take me to do a similar rebuild job. Mainly because I'd forget to order some parts along the way, or find plenty of other issues "while I'm in there" to remedy. Because, scope creep.A MONTH to rebuild? Six weeks? Give me a break. Comments like that only enhance the mis-understanding of the task at hand on here.

This price is a bit higher than it used to be, when it was in the $3-4K range. Probably risen with inflation and such.Roughly $4,200 plus a $1,200 core charge (the latter is refundable). Add another $1k for removal and install.
Where does one get a non-reman, new 722.3 transmission? Do you have a source for these you've been holding back on us about ?!?Exactly I think only a new 722.3 MB transmission is the only way forward here and not remans. (MB or otherwise)
Don't forget about the torque Converter too, whilst in there.
Indeed whilst in there you must also renew the rear crank seal, crank seal plate, all TTY bolts, shifter bushings, centre support bearing, transmission blanket, mounts, NSS, crank sensor, flex disc and starter motor.
I am assuming you are making reference to the six weeks I said it took me. If so, everybody should keep in mind that my car was not operational anyway, so I had NO reason to rush (eventually that car never ran and I ended up donating the body for scrap metal few years later). In addition, an automatic transmission was a totally unknown territory for me (it still is, though I feel more confident now), so I took my time in doing it and I also had to stop at times and order parts I did not know I will need.A MONTH to rebuild? Six weeks? Give me a break. Comments like that only enhance the mis-understanding of the task at hand on here.
Ahah starting to see it are we?Where does one get a non-reman, new 722.3 transmission? Do you have a source for these you've been holding back on us about ?!?
I do know for sure that the "reman" places like Sun Valley do provide rebuilt torque converters with their remans. They actually showed me when I visited what they do to refurbish these TCs. It's not trivial!
Transmission blankets for the .036 are NLA, and have been for the past couple or few years. I have a NOS example I bought from the @IslandMon, and offered it to anyone who has the interest/willingness to reproduce a replica, but no one took me up on the offer. So I'll likely use it when I pull my own transmission out.

I am torn on the "numbers matching" things vs. non numbers-matching. To me personally, I'd always prefer to keep my car numbers-matching, which is why I've augured toward doing the rebuild myself when the time comes, and I've acquired most of the parts to do so. It's not that the E500E is the same in rarity as a Gullwing or 540K, nor is my car in collector condition, but I have always been desirous to keep its major components the originals, if at all possible.
You didn't see my![]()
It was said in jest, hence the smilie.
Well, you DID say that it's quite often that when the reverse goes out, the forward gears, friction discs, and so forth are often in excellent condition. The inference that any reasonable person would take away from that statement, is that if something is inspected and found to be in great condition, it doesn't need to be changed or messed with. This was made with people also knowing your mechanical and technical abilities to zip a transmission out and repair it and re-install it in mere hours. So yes, explicit is a good idea.
I'm not sure where the ridicule from people who have never built a transmission comes from. Speaking for myself only, I certainly didn't ridicule anyone -- in fact I "explicitly" agreed with you in a later post that doing the job ones-self is the most preferable option, all things considered. I didn't see anyone else ridiculing those who have rebuilt their own transmissions. I think the prevailing attitude of average punters here of said "transmission 2%ers" is much more one of admiration, amazement and respect, not derision. And of course, that the "transmission 2%ers" will create a HOW-TO on how to rebuild a transmission comprehensivelyThe @gsxr, in particular, is waiting for that HOW-TO with bated breath!
Unfortunately, as @TimL's and the @Jlaa's recent testimony shows, as well as others in the thread like myself (E320 wagon with Sun Valley transmission back in 2014), @Glen and @nocfn and @TerryA, rebuilding a transmission is not an option (for whatever reason) for 98% of the forum members. As I earlier said, the vast majority of folks — even highly technically savvy folks — here will pay to have this work done.
The main point is that we have options, and they span the gamut from relatively cheap, to modestly expensive, to doing the work ones-self for the cost of the parts purchased.

A How- To of course may inspire some and whilst I'd like to provide same myself (in addition to the re-seal thread already done) it would most likely be years until I'm working on a 722.3 again. Mine are all performing very well with no delays or other issues at the moment. It is likely other members so inclined would get to it before me.I am assuming you are making reference to the six weeks I said it took me. If so, everybody should keep in mind that my car was not operational anyway, so I had NO reason to rush (eventually that car never ran and I ended up donating the body for scrap metal few years later). In addition, an automatic transmission was a totally unknown territory for me, so I took my time in doing it and I also had to stop at times and order parts I did not know I will need.
Therefore, my case should NOT be considered a general rule. In fact is exactly the opposite and I had no intention to enhance the misunderstanding of the task at hand here. If I did, I apologize., it was w/o intention.
That reminds me. ~10 years ago when visiting Schmid to pick up a 722.3, someone had a few minutes to chat with the tech who was doing the rebuild work. Asked how long it takes, he replied "About 4-5 hours total". Granted, that's from the guy who does these literally every day. And it also gives you an idea of why some of the results might be, ahem, sub-optimal. Sun Valley dyno-tests their transmissions after the rebuild, I don't know if Schmid does.A MONTH to rebuild? Six weeks? Give me a break. Comments like that only enhance the mis-understanding of the task at hand on here.
At an absolute minimum, remove all of the side covers on the valve body (one at a time) to inspect every spring and piston. It's not uncommon to find broken springs, which will cause even a perfect rebuilt transmission to have shift problems. Very few springs/pistons are available new, so if any are broken, a used donor VB is needed to borrow parts from.... (Split valve body if you wish) ...

None of this valve body work and inspection should really be necessary when pulling a transmission and re-installing it, solely to remedy a failed reverse gear and perform an external re-seal.Also, as I described in other posts, a perfect transmission can shift absolutely terribly with a defective valvebody. I don't know what the major rebuilders (Sun Valley, Schmid, etc) normally do with 722.x mechanical VB's. Do they remove the side plates for cleaning & inspection? Split the VB halves? Rinse it in solvent and call it good? I have no idea.
Correct. If the trans is shifting normally, there's no need to mess with the VB if the reason for the work is a re-seal / reverse clutch replacement.None of this valve body work and inspection should really be necessary when pulling a transmission and re-installing it, solely to remedy a failed reverse gear and perform an external re-seal.

Apologies but my posts #57, 60 & 61 were primarily chain yanks (feigned shock/ anger) and should not be taken literally![]()
Correct. If the trans is shifting normally, there's no need to mess with the VB if the reason for the work is a re-seal / reverse clutch replacement.
My point was that people should inquire about what exactly a shop does during a rebuild, as omitting a VB inspection would be a bad thing, particularly if the shop does not dyno-test afterwards to run the trans through all upshifts/downshifts.

Joe, I'm sure all of us would love to get a video tour of your how your garage is organized. Maybe a several minutes long video some time?I pull all useful parts and store them in clean sealed parts bins for future use. Cheap insurance against NLA parts
You should remove the transmission and ship it to JC220. I'm sure he'll make short work of making it work correctly again !!my transmission was rebuilt by Schmid a few years back,never worked correctly since.i just live with it.when it goes from 2nd to 3rd it goes back to 2nd then 3rd again.
Based on my personal experience, at this point you're ONLY 2 rebuilds away from a more or less satisfactory resultmy transmission was rebuilt by Schmid a few years back,never worked correctly since.i just live with it.when it goes from 2nd to 3rd it goes back to 2nd then 3rd again.
What was the original complaint? Reverse delay?my transmission was rebuilt by Schmid a few years back,never worked correctly since.i just live with it.when it goes from 2nd to 3rd it goes back to 2nd then 3rd again.
You place an emphasis on matching numbers and I don’t. Whatever floats the respective boats.I believe originality is imperative on a collectable & rare car such as the E500E. (300E not so much at all) My 500E is numbers matching and will always stay that way.
If I were buying another 500E you bet your A I'd have it on a lift to check numbers and If there was a mis-match the vendor would be informed and my offer reduced unless they have retained the original trans and supply with the car. Call me crazy but that's the way I see it. Indeed thepeanutwalnut gallery on here would sure point it out in a FS thread If it was evident.

Sun Valley charges 1750. for the trans IIAC. Where is the other 2 grand or so going?Sun Valley in SoCal will either rebuild your original trans if you ship it to them, or they’ll send you a rebuilt unit from their stock, and you send them back your old one. Your choice.
You need to budget $3-5K for this depending on if you remove the trans yourself, or you have it done at a shop..
I think that was factoring in paying a shop to do the work, plus fluids & whatnot... the $3k-$5k number may have included the Sin Valley trans; not added on top of the trans cost.Sun Valley charges 1750. for the trans IIAC. Where is the other 2 grand or so going?

Hello Guest !
We wanted to let you know about a new resource that is now available to all 500Eboard members. This is a comprehensive database of all US-market (and soon to include Canadian-market) 500E and E500 models delivered for the 1992 through 1994 model years.
Data for this resource has been compiled continuously since mid-2003, and much of this information is seeing the light of day for the very first time ever. This new resource will allow you to utilize 500Eboard research and resources to track specific cars, their sale history, documented modifications, and other information that has surfaced over the years.
We are also providing analytics about the cars' production. This means that if you are curious as to how many "Signal Red" cars were produced for the US market with a black interior, specifically in Model Year 1993, you can now easily find this information. You can also find aggregated information -- for example, how many "Black Pearl" cars were imported into the US over the three-year span.
You can always find and enjoy this resource by clicking here (bookmark the site for easy reference!), or by going to the “500Eboard Registry and VIN Database” sub-forum below. You can also find a VIN Database button at the top of your screen, for easy access.
We hope you enjoy this resource. A LOT of blood, sweat and tears over nearly 23 years have gone into its creation.
Cheers,
500Eboard Management
