240 auto transmission AGAIN!

Sep 10th, 2002, 12:00

Hello again,

The auto box on my 240 has been making some strange noise and partly lost drive in forward and completely in reverse.

It sounded like it was overfilled..so I checked the dipstick and it was showing overfilled...but I know for a fact that it used to read fine only 6 months ago.

I have taped the sound it makes, as just an audio file and as a video..

Thanks for any advice you can give.

Hmmm... The way you describe it, additional fluid has entered the system without your help. Hmmm...

I would definitely check the state of the ATF oil - in a hurry!

What I suspect, is that you may have a leak in the "cooling insert" (haven't got a better term for it) located at the right hand side of the radiator: The trans fluid is routed into the radiator where it is cooled and returned to the trans. This is the only place I can imagine the transmission can pick up additional fluid.

Check oil, and check coolant. If my guess is right, you'll have a mixture in both systems.

Many thanks Erling.

Unfortunately it is not this! This did happen last christmas, and I have done 10,000 miles in the car since I replaced the radiator/hoses/water pump and flushed all the fluids.

I am at a loss!!
