The problem still with shifting

[Almomen]

Since I have had the seals for the transmission changed in 2019, the first gear shift when I start to drive delay with high idle ( may be termed flair), as I have mentioned this in earlier posts last year I asked a work shop to check only the vacuum lines only connections, he said he did change one of them,
this action by the work shop didn’t do anything, ,in the contrary, the car delay the shift 2nd to 3rd but only when the temperature reaches above 80°. So now it delays when first thing when it is cold the car then runs smooth until it reaches above 80°
Recently I have changed the modulator, but things not changed notably!! I hate driving the car with this issue

Is this a 400e or 500e?

 

[Almomen]

E500 Terry

Does the car has transmission coolant I wonder?

 

[nocfn]

Do you have a stock valve body in your e500e or is there one from a e420/400e?

 

[Almomen]

No I don’t have one, but the mechanic I’m dealing with says that he can ( clean it) is this possible? Is it surly from the valve body? Or is there any possible cause?

 

[Almomen]

I guess it is stock one

I don't understand the exact problem / symptoms here. Can you explain in more detail?

Also, was the transmission shifting normally before the seals were changed in 2019, and since then it has never shifted correctly? Or was it OK immediately after the seals were changed, and the problems started later?

exactly, after changing the seals, taking the car was worm so nothing was noticed, next the car was cold i noticed flaring in shifting ( the car delays shifting comes with high idle sounds before it shifts ) I know that it is normal for this transmission when cold it delays, but this time it was different, surly some thing went wrong. The day after I asked the technician to test the car when it is cold, he noticed the difference he , as he claimed, tuned the modulator, but the car still had the same issue. Last year I took the car to another mechanic requesting him to change the vacuum lines , I believe he didn’t test the car and claimed that the car is fine. Now the car not only maintained the same issue but when the temperature is above 80° the car flares in the first shift and in the second shift ( I understand that the car take off from the second gear) . I hope this is clear to you.
I will turn the car to the first mechanic who I trust more , he will clean the valve body , he claims. Whether this is possible or not I really don’t know but I hate driving the car with such issue.

The mechanic recommended cleaning the valve body , is this a sensible action to do ?

If the transmission flares at all full throttle (WOT) upshifts, the vacuum modulator should be adjusted firmer.

If the flare only occurs at part throttle upshifts, or only on certain upshifts, that may be related to the valvebody. Cleaning may or may not help, but all the spring trains (especially B1, K1, K2) should be removed and inspected for damage. Broken springs can cause flaring but generally would only affect 1 particular shift, not all shifts...

Thanks for the information, I will give update of what happens although I m sceptical about it

The mechanic did the cleaning of the valve body but the car now is worse not only delay shifting in the first gear but in the second, as if it is slipping kind of, I don’t know what to do

Hello
recently managed to change the valve body, the gear shifting was very smooth but something came up during the second shift as if it shift down and comeback again normal, the mechanic said the car burn the oil inside is burned,
Another thing, when car is in park and try to start the car move forward a little
The mechanic suggested over hauling,

Any suggestions
