I believed my transmission pan gasket was leaking at the trailing edge of the pan. I purchased a kit and replaced the gasket and filter. The old gasket looked a little worn, but had no obvious defects. I throughly cleaned the pan and mating surfaces per instructions found in this forum. I then carefully replaced the pan and torqued all bolts to 14lbs. I am still getting what appears to be a leak from the trailing edge of the pan. I tightened the 3 rear pan bolts down another 3 lbs and am still getting leakage. I am now thinking that the leak must be coming from above somewhere. It is strictly leaking from the rear of the pan, slightly more on the passenger side half of the pan. I am getting quite a bit of blowback onto the rear differential, muffler and gas tank skid plate. I appreciate this forum, it is a great resource for guys like me who have little idea what they are doing, but can follow directions pretty well.
really? i have to admit, that is a new one to me. how do i get to that bad boy?
lol i have to think you didn't do any kind of inspection before changing the gasket?Before you run out and buy a back up light switch do a careful inspection.I'll bet the leak is very obvious.Just follow the oil trail forward.I'll bet if you pull the electrical plug off the back up light switch its soaked with oil.But do some close looking and find the leak this time before changing anything.
To replace it simply remove the frt drive shay from the frt yoke.Move it to the side and you will have easy access to tye bkup light switch.I believe its a special oil sender socket 1 1/16 if my memory is correct.
You may be right in laughing at me. i inspected it as best i could and the back of the oil pan seemed to be leaking, but you really can only get kind of an angled look at it from underneath with the skid plate in the way. Since i had no idea how long it had been since the previous owner had changed the filter, i figured the best course of action was to go ahead and pull the pan and replace the filter and gasket. As mentioned above, the old gasket had no obvious defects and as far as I could tell I had no bends in the pan. So I cleaned it up and put it back together, but still have the leak, with the evidence in the same spot. Rear of the pan. So obviously i am beginning to wonder if it was something else. That is why I was asking for other ideas. Yours certainly sounds possible.
I gotta tell you a story that will make you laugh.I went to look at a 98 tj that the guy just spent 1000 dollars to have the transfer case leak fixed....guess what.........yep you guessed it.The only thing wrong with it was the back up light switch was leaking.He was pissed.
If you just remove the frt of the drive shaft from the frt yoke its much easier to inspect.
yep, I have this same leak. Although the parts department sent me home with the wrong switch. It will fit in the hole but the plug won't fir it. And my plug is bashed up so I don't care if i have to splice on a new one to make it fit. Amazing so much can leak from one little spot even when the switch seems to be in there pretty snug

A frequent hard-to-find ATF leak is from the speedometer gear housing where it bolts to the transfer case, especially if someone has replaced the speedometer gear. The big o-ring gets nicked and then it starts leaking ATF and it looks like it's coming from everywhere but there.
