a couple month ago, I posted a picture of my leaking tranny asking for help.


so, last week, I went to dealer to replace the servo o-ring and oil pan gasket hoping these would fix the leakage. after that, I cleaned the tranny to see if it's still leaking.


4 days later, today, I took a look at the tranny noticing the tranny is still leaking. I can see ATF under the servo cap, and I also can see ATF on the top of the tranny near the dipstick.

the mechanic said my rear main seal was leaking too, would that be the problem?
what seals would leak ATF if it's going?

thanks

A RMS leak wouldn't cause trans fluid to be on the outside of the trans...or anywhere else, for that matter.

Which seals/gaskets? Pretty much anything that's externally facing could possibly leak trans fluid onto the exterior of the case.

 

It's not the engine rear seal if it's ATF. Pull the bellhousing access cover plate and see if there's tranny fluid in there. There's an input shaft seal (actually the front oil pump seal) that could leak. There's two speed sensors, the breather hose connection and the dipstick tube "O" ring that may be the leak source as well I suppose.

 

eeeeh, sounds hard. I don't think I can do it. which seal is on the top near the engine valves?

 

I guess I found where the ATF comes from. It's the powertrain revolution sensor.

does anyone know what kind of O-ring the powertrain revolution sensor uses?

 

Here's the O-Ring: It's top right of the picture (31051J)

thx, I followed your link, it's actually this pic, cuz mine has 2 sensors.

 

If I am not mistaken the leaking RMS is visible by oil appearing below the motor right where the motor and trans meet by the black inspection cover.

I am suspecting mine has a leak there since i will see a drop of oil after about 2 days of no driving. Doesnt matter since the car does get driven daily! I do want to get an estimate for the same.

 

mines like leaking from the top, the front of the tranny is covered in tranny fluid. servo o-ring and pan gasket have been replaced, but the damn thing is still leaking.
