Serious tranny issues!!! Please help!

Ok. I have a 94 ZJ with the 5.2. Yesterday while I was driving I noticed a whole bunch of fluid on the back window and all over the hatch. I looked underneath the Jeep and saw tranny fluid ALL OVER down there. Then today, I wiped everything down, refilled the tranny, and tightened the bolts on the tranny pan (I had a tranny service done and thought maybe they wiggled loose). It didn't leak at all when I drove it after that. I thought I fixed it.

Later on tonight, I was driving home and I hear a "pffffffffffff" sound. I look under it when I got home and, in 6 blocks, it pissed all the tranny fluid back out and, again, it went everywhere. So much so that I can't even tell where it is leaking from. It's obviously building up too much pressure but why? I didn't overfill the tranny, I didn't do anything other than tighten the pan bolts.

Has anyone else had this problem or know what is going on? Any info would be greatly appreciated!

Rusted tranny cooler line is my guess. Not sure how it got on the back window. Thats incredible. Maybe it sprayed on the tire and that shot it all over.

I'm afraid I'm not familiar with the 5.2

However, my dad had a problem with his tranny in his 4.0, after the fluid was filled by a local shop. Something about having to test the level with the jeep in "neutral" instead of park, they did it wrong and screwed up the fill.

Probably not what you're dealing with, but it was odd enough I just wanted to throw it out there.

This link from another spot in the forum has some common problems/fixes for the Transmission. (#11).

Good luck!

I'm voting tranny lines. Exact same thing happened to me, it was half *** mechanic job, though my dad tells me when he first had it fixed it was because the tranny lines had rusted out. I would check there, and replace.

Air flow caused it to get on the back window, Any type of fluid leak will end up on the back on the lift gate/window, Be it the rear end or tranny,

I had a rear dif/driveshaft seal go on me once and everything stayed underneath somehow. Stunk too!

Pressure cant be too high its not a pressure system. I would check the lines to the radiator. Other than that the gasket to the pan is it one of the god damn rubber ones? I had lotts of fun with one a few years back kept blowing out the side when it got warm. The 46re requires a cork and metal lined gasket, These Mexican rubber gaskets do not do the trick. If you tighten it more than finger tight with a rubber gasket or as I call them rubbers they slip out the sides. Or heat up and blow out the side. Def not made by Trojan.

3 weeks ago I was on a long trip up north and noticed in my rearview nothing but an empty highway and blue smoke. ended up blowing a trans line and while fixing it road side I noticed that my entire front end and everything under them hood looked armoralled with trans fluid along with fluid all over the back window hatch bumper and my two buddies trucks who unfortunally had to ride behind me until I could get off the highway

Thanks for all the replies! I found out that it was in fact the tranny cooler lines. But instead of rusting out, a clip was missing to hold the line into the tranny. I went to the dealership in town and they had no idea what the hell I was talking about. Neither did about two other dealerships. So I went home, got some safety wire and safety wired the piss out of it! It hasn't leaked a drop since.

And to Kevinyj95, it is a cork gasket, not a rubber one.

Never seen the plastic and rubber ones. Just the flexable gummy ones that slip out. Autozone/advance.
