leaking transmission pan

[Mr aircraft mechanic]

I have a 2004 Jeep Liberty 3.7l v6 with about 152k on it and the transmission pan is leaking from the drivers side
any suggestions on what might be causing it

The OEM 42RLE transmission pan were stamped steel, and warped from heat, especially around side or the bolt holes.
Transmission RTV was used and after a year or so mine would start to leak.

I ordered a PML 42RLE machined aluminum transmission pan, & used a LubeLocker gasket.
Pan kept ATF+4 fluid cooler, and zero leaks again.

Should Replace the transmission filter while there...

 

[Mr aircraft mechanic]

thanks that really isn not what I want to hear, but when does anyone want to hear the need a new pan.
Thank you
how much is an aftermarket temp sensor kit the car is for the most part stock.

 

[LibertyTC]

IMHO the temp sensor will not be required as the new aluminum pan keeps things very cool.
PML charges an additional $75 for drilling a temp sensor hole, if you required one though.
Ever since I installed the PML pan, never again did I get an overheat/ TransTemp light again.

[Mr aircraft mechanic]

thanks man, really helpful
sadly I cant afford a new pan right now so I will have to watch it and make sure its doesn't loose to much fluid

 

[LibertyTC]

Ok well, the cheaper option is to hope that a new kj 42RLE stamped steel transmission pan may still be available. Then use a LubeLocker gasket. and torque it to spec.

 

[Mr aircraft mechanic]

any I idea what the toque spec might be

 

[LibertyTC]

Standby I will edit in the Lubelocker spec shortly...

I had to replace mine (03 Liberty) because we live in Wisconsin.....and it rusted a whole (several) in it. You can get them at O'Reilly's for $40 bucks....

Assuming 42RLE
First, Lubelocker - terrific recommendation. Deep pan IDK.
All of my (3) Libertys have 200K plus.
Anywho.....
BUT...IF the proper bolt is not thread sealed it will leak no matter what you do.
It is specifically one bolt...Ask me how I know. I mark it with a paint pen on the pan.
And yes, I would go look but neither one is with me at the moment. Sorry.
But wanted to post and say you aren't crazy and it doesn't require anything super-special.
Just the RIGHT thing in the RIGHT place.

OK found it.... Bolt #5 might even be marked.
From the FSM
"NOTE: Before installing the oil pan bolt (5) in the bolt hole located between the torque converter clutch on and U/D clutch pressure tap circuits, it will be necessary to replentish the sealing patch on the bolt using Mopar® Lock & Seal Adhesive. "

When I was looking for a replacement for the porous pan on my WJ, I hit on the Dorman one with a drain plug. Beats the OEM one every time, after all it's the rubbish quality of that which was the cause of the problem.

 

[David13]

I didn't have any leaks but I did have some solid rust going, and I wanted to get to the filter, and fluid. So I got an OEM pan which I think was $46. Not bad. The LubeLocker gasket I think was $25, a lot for a gasket but reusable. The filter was rare but I did find one.

There may have been one other brand with a drain hole. That would probably be a good idea.

My trans never overheated only when I was on the Shafer Trail switchbacks in Moab. But my friend with an FJ said his overheated when we were going up a sheep trail.

There are 2 filters, come as a kit/pack from any major filter manufacturer, still generally available - afaik.

I had to replace my oil pan due to rust issues (I'm in Sweden where we have a lot of winter with salt on the roads)
I hit a stone with the oil pan while wheeling, and it was beyond repair ...
I went with this kit from Ebay and added locktite "maka-a-gasket" It's $80.
Has been holding on with no issues ever since (I did though mount a skid plate afterwards )
