Hello All! New to the forum here. OK. This is what the problem is. Engine was rebuilt in the truck about 1500 miles ago. Transmission had a leak before, but not as bad. I thought it was coming from the pan or the dipstick, but it is not. I first replaced just the pan gasket, as it looked to be coming from around the pan. Still leaked. I have replaced the dipstick tube, o-ring, transmission pan (thought maybe bent pan) and pan gasket. When I first cranked it up and let it idle for about 10 minutes, there were no leaks. I drove to the gas station about 1 mile away. When I got out, I saw the leak was back. It is coming from what looks to be the rear of the transmission pan, maybe just right above it. The rear seal (where driveshaft enters rear of transmission) is dry as a bone. Front of transmission is dry as a bone (except for just a little where it started running towards front of pan after driving the short distance). There is more fluid (good bit) on the rear of the pan and the transmission cross member.

 

By the way, this is 2 wheel drive.

 

Bump, I have the same year/trans and have also replaced my pan gasket. Exact same leaking situation too, anyone have any idea where it could be coming from?

 

Extension Housing to main case gasket?

 

Please excuse my ignorance, but where exactly is that located on that trans?

 

Fluid mostly on the left side? Trans shifter shaft o-ring.
The tailshaft housing gasket is not on the shelf at the dealer. And the only place to get it. I have one i will sell it to you for 1/2 off what they want
