I know this doesn't really pertain to the car guys, but I figured that somebody might know whats going on. It's a Level 4 4L60E from FLT. I know for sure that it's nothing to do with the transmission itself. Was working perfect before the converter install. Still drove great after.

I swapped the converter out to a yank 2600 TT. Filled it with ~1 1/2 quarts of fluid. Install went fine. Then I installed a B&M deep trans pan. It was a pain in the ***. Directions sucked, etc. Torqued the bolts with the cork gasket to 8-9 lbs.Anyways, after I got everything back on, I Filled the trans with 6 quarts of fluid. Started the truck, then it started to leak around the front of the trans pan. Turned it off and retorqued the bolts to 12 ft. lbs. Turned it back on again, no leak whatsoever. Added 5 1/2 more quarts, checking the level after each one. Total of 11 1/2 quarts + 1 1/2 in the converter. Drove it around for about 10 min and came back. Had 2-3 drops of fluid on the back of the pan. I could not retorque the back bolts to 12 ft lbs, due to the exhaust. Figured it would be okay until in the morning. Drove to get something to eat on the way to work tonight, about 10-15 min from my house. I was in the drive-through and smoke was everywhere like something was on fire, I jumped out and looked under my truck and fluid was just dripping everywhere. I pulled over and immediatly shut it off. The whole driveshaft, undercarriage, everything was wet with trans fluid.

Could it be just a loose trans pan? I think I'm gonna put the regular pan back on when I get off, in the parking lot. That's gonna be fun. After that, if something happens I'm gonna have a nervous f*cking breakdown. I've had about 6 hours of sleep in the last 2 1/2 days because of working on this ****. So please, if anybody has any input, I would appreciate it. Thanks

 

funny how truck guys find truck guys LOL...

I'd put a rubber pan gasket in there and use some loc tite on the bolts. torque them in some kind of pattern to make sure they are pulled up even and you should be good to go on the pan... strangely, you arent the first I've heard having problems with the B&M pan, you might want to check out the derale pan as well...

 

One thing to check would be to make sure there is not a harness pinched in between the pan and the pan rail of the case.

Rinse it off very well wit brake cleaner or something similar, get it dry. Then run it briefly in order to determine where the leak is. Then go for the fix. It may not be the pan.

Good Luck with it.

Yeah, also make very sure you didn't lose one of those E-clips for the cooler lines, I had that problem. Didn't realize it was gone until it was spurting out everywhere on the highway. Ive also had my connector for the wiring harness fall back into the pan and fluid came shooting out of there too.

 

First thing I would do is get rid of that cork gasket. If it isn't leaking already, it probably will

 

That's what it was. Didn't loose the clip, just thought it was secure and it was loose the whole time. Thanks for the tip!
