tranny shudders when warm

[callen]

My 89 735il with 150K miles shudders at low speeds when pushed only after driving it long distances at high speeds. Have replaced filter and fluid with no change.....course didn't change out fluid in torque converter..thinking about draining it again...also what's the model number for transmission. Rebuild kits available.

Thanks

as for example which tranny you have. I have it under my favourites. Just type in the last 7 letters/numbers of your VIN (chassis number) and you will get interesting data on your car. Among others what month/year produced, engine type, trans type etc.
There are many VIN decoders online like on my page, on Johan & Sean's page under miscelanoeus links.
Have you tried to change the trans mounts? I have changed engine and trans mounts some weeks ago and the car now runs remarkably smooth. Just one of many possibilities of your prob.
Used trans or remanufactured are of course available.
