Tranmission Oil Cooler
I am thinking that my transmission leaks from this cooler. I am going to change out the o rings and see if that stops it from leaking. It only leaks a few drips a night. My question is there anything else I should look out for? Also is there a gasket for the oil pump on the transmission?

No - you can remove without opening the pump.
Pull the cooler and the rings seat in the transmission housing. You'll need to drain the transaxle first and you'll also need a little bent tip pick to pull out the o-ring seal.

Correct. The cooler is held to the transaxle by some compression clamps via hex bolts. The cooler fitting slides into a bore in the transaxle. In the bore, about 1/8" or so deep, are the o-rings. They just fit loosely in the bore housing.
To remove the cooler, undo the compression clamps and just carefully work each end of the cooler out. Then, fish into the bores to tease out the o-rings. Do the reverse to re-install.
Short of the generally tight working space, shouldn't be very difficult.

BTW, you might want to check your output flange seals to see if that's where your leak is. Check the input shaft seal via the inspection hole as well.
I'd think any are a candidate to leak.

I have the same issue ... Got grilled asking where this leak is coming from
I was told ( by Tom) to be careful when replacing the o ring that it doesn't wind up in the rear diff... It can fall in there when replacing it ... I haven't done mine yet as I have only cleaned off one side of the rear diif so far...
The stuff is the worst **** to remove
It took 2 cans of gunk and I have yet to do the other side ...
Good luck

A couple of comments...
#1, its not a big deal if the o-ring falls in, it will easily get chewed up and come out next time you do a gear lube change. No, thats not the ideal thing to have happen but it really isn't a big deal if it does. Your gearbox won't suffer any damage.
#2, the cooler comes off easily, but don't put too much force on it as they can break. If you have to force it while removing it or re-installing it, you are doing it wrong.
#3, its easy enough to replace the cooler o-rings that I would suggest you start there and see if that solves your problem. Worst case scenario is that they are old and need replacing anyway.
