My mom's '02 ATX is leaking tranny fluid

nofrills05 · Post by **nofrills05** » Wed Mar 24, 2010 3:52 pm

She only has about 40K on an '02. Very lightly driven. It has been leaking for a few weeks now. I am going under the car tonight to see what I can find.

Any thoughts on a cause?

has she ever had it in a shop for anything tranny related?

On 9/27/08 she had the transmission fluid and filter changed.

Just like me the buggers didnt seal it up correctly and it leaked around the seal...friggin useless pricks took chrysler 3 times to re seal it!

Or it could be the cooler line beginning to weep.

If silicone was used to seal the pan, I doubt it would take a year and a half to begin to leak. Unless she hit something.

RTV silicone is either success or fail. Once the stuff fully cures, and is properly bonded, you can damn near remove the screws, and it will not leak.

Well, I did an oil change on her car just now and looked around. I cleaned the pan because there was trans fluid running down it - pooling near the back of the pan. It was sealed with RTV.

This may very well be a pan leak. I am going to check it out tomorrow to see if I can determine the location of the leak. I checked the cooler lines and they were fine, no fluid residue.

Also you may want to check the solenoid pack my old solenoid was leaking and running down the pan towards the back...normally you would assume the seal isnt sealed proper...but check the solenoid as well

That too. It can run down onto the pan flange, making it appear the pan is leaking.

You may need to spray the whole thing down with brake clean to get it nice and dry, then see where it is seeping from.

Thanks for the tips guys!

I have some brake clean and will spray it down tomorrow and check the solenoid area.

Just be sure it has evaporated completely before keying on, in case there is some kind of short/bizarre reason for an arc. You just never know. Spraying highly flammable stuff around wiring can have it's drawbacks.

Yeah. Thanks for the tip.

Ok, so I determined it to be the solenoid. If the car is shifting fine it is just the gasket that I need to replace, and not the $150 solenoid...correct?

as long as the car is shifting fine, just replace the gasket. Hopefully it is sold as a separate part, not too sure.

Be sure to clean around the solenoid really well before removing it. Dirt tends to get caught up behind it, especially if it was leaking and you don't want it getting into the trans when you remove the solenoid. Toothbrush and brake cleaner worked for me.
