Hey guys, this is my first post on here. It's been awhile since I've used forums, but I'm hoping I can get some help here. I have a small shop, and have been periodically working on this gorgeous 95 E420 I have. When I first got the car, 3rd and 4th gear were near non-existent. Could never get them to engage. I've replaced the kickdown switch behind the pedal, I've properly adjusted the kickdown cable on the throttle, I've drained the trans and torque converter, replaced the filter and K1 spring assembly, then added new Dexron 3 fluid. Now the car runs a ton better, but I still lose 3rd and 4th gear after about 15-20 minutes of driving, and then I only have 1st and 2nd gear. It acts like it loses fluid pressure, or is the wrong fluid (It has the right capacity of fluid).
I'm at a loss right now, and have set it aside for our other projects. Any help or ideas would be appreciated. Thanks!
