Severe leak!!!

I have a pretty bad leak coming from my 1994 YJ. The leak is coming from somewhere above the skid plate that protects the tranny and t-case. The leak occurrs after driving the jeep and when the engine is off. The fluid smells like gear oil....I topped off the tranny yeaterday with approx. 2.5 bottles of gear oil. has anyoone experienced the same issue and how much/difficult is it to repair. WHAT A MESS!!!!

I Don't think it takes Gear oil in ether the Tranny or T-case, I run a Auto so I may be wrong!

Probably the seal between the trans and t/c. Maybe the gear oil is too thin?
Anyway, probably the case of a $5 part and $500 in labor--I hate those.

Like Nubby said, gear oil not for trans, just for your differentials.

I went to the auto store to get tranny fluid and the parts guy said that 1994 and older require gear oil for the tranny........I hope he was correct cuz I took his advise and used it.

Yes, transmission uses either gear oil (original spec) or 10w30 motor oil (updated spec). Either is fine in the AX-15.

depends on your skill level. you'll have to seperate the t-case from trans, 6 bolts. drop both drive shafts, disconect linkage to t-case. is it sounding difficult yet. then pull the seals and replace.

Not being flippant here, but make sure you check the fill and drain plugs to make sure they are intact. I assume you recently tightened the fill plug after adding the oil.

clean and check

Best to clean the area and then check carefully to find where the fluid is coming from. Once you have pin pointed the area you can likely determine the leak and what will be needed to fix.
