1990 300SEL Transmission just quit
 

Hello everybody !I owned this car for a little less than 2 years and put about 20k miles on it. It had some startingproblems but ran and shifted perfect after starting. Until the other day, when I drove to the grocerystore, only 1 mile from my house. It hesitated shifting up, but did so after getting of the gas a little. After parking the car and doing my shopping, I came back after about 20 minutes and started the car, now it would not move shifting it thru every gear. It didnt even pull a little bit.After having the fluid and filter changed the next day it is still not moving or pulling . It is hard for me to believe, that the transmission would just die like this without any previous trouble. What should I look for before replacing the transmission. Any advice will be greatly appreciated. Another Question, will a transmission from a 1992 300E [WDBEA30E4NB547024] fit my car[WDBCA25D4LA532057]?

Thank You and a happy New Year to everybody, Leo!

I agree...that doesn't sound right...automatic transmission don't just die like that....they go slow like....

They sure do fail randomly. I drove to the lake one day last July, when I got home, reverse was just about gone and I had a weird swishing noise. Reverse band was blown, so I had virtually no reverse and a very unreliable 4th gear. It kept getting worse over the next 100ish miles until it was having problems shifting through any gear. I swapped it for a low miles used unit, which, 7k later, is still working great!

When did Mercedes start with the electronical controlled Transmissions? Wasn't that started in 1989 or 1990?

1996

Usually there is a bit more warning, but if something catastrophic happened, who knows. I'm not the definitive source for this answer, but I believe that no, those trannies are not interchangeable. The '92 would have had an M104 motor (I think) whereas your car has an M103. Somebody here could give you a better answer, I'm sure.

Double check that your shifter linkage didn't come undone.
