Had my stock transmission rebuilt by Jack's Transmission a couple years ago and installed it with the stock transfer case. The car has sat for most of that time (JSB) but a few months ago began leaking trans fluid. What would cause this to happen? There were no leaks before the rebuild.

So it's probably from the transfer case output shaft seal. you need to pull the downpipe and transfer case first to make sure its from there, once you can see the seal and verify its leaking then you can start removing the transmission. I just replaced mine.

Appreciate the advice. Seal looked great when I installed the rebuilt trans. Should have just done it when it was out (how it always goes). Now to get to it with the least amount of effort.

Are the fluids the same in your trans and t/c? Can you tell which is leaking based on the fluid?

ok now this requires a set of balls and a little bit of skill.

lift up front end, put on jackstands, drain all the fluid, remove driver side axle completely, drop downpipe, remove transfer case, (this is where the set of balls is needed) place a block of wood on a jack and rest it just under the transmission, unbolt the transmission mount, remove the starter, unbolt the transmission from the block and seperate them, this is all relying on the jack to hold the transmission in place, now unbolt passenger strut(leave axle in) and seperate the transmission even more, now there should be some room to get in and see the output shaft seal clearly. this is were the bit of skill is needed, take a flat head screw driver and punch it through the seal, do this a few times till the seal breaks loose and come out. slide it off the shaft and let the left over fluid pour out. clean everything real good with a rag, no brake cleaner. once there is no more oil around the seal seat put a light coat of RVT on just the lip of the new seal and press it in by hand as best you can. i was able to get mine in with just my finger, if you have a hard time getting it pressed in you need to find or make a rubber punch and a rubber mallet and lightly tap it in till its sealed. then put everything back together... i did this in about 2 hours the other day.

Quoting iceman69510:

Unfortunately they are the same fluids. I had already thought about that and if they were different that would have made troubleshooting much easier.

This sounds so much easier than dropping the trans completely (especially since I'm limited to just a jack and stands in my garage). Skills...check. Set of balls...hang lower than they used to....check. Now I just need to carve out some time to do this. Thanks for the details. Are the seals the same for the DSM and GVR-4 transfer cases? Can't remember which one I'm using since I'm not under the car right now.
