I recenlty noticed a substantial leak coming from my newly rebuilt TH350 speedometer gear sleeve. When I went to pull the sleeve out a massive amount of trans fluid started to pour out. Is that much trans fluid supposed to be in the nose of the tranny? Help is appreciated.

you mean the tail end. if the vehicle is sitting level the fluid level will be level with that of the fluid in the pan, the speedo gears and govenor must have fluid also. if the rear is jacked up, the fluid moves to the front of the tranny so less of a fluid spill, when I did my speedo gears, I parked on a down hill slope and backed the car on the ramps and lost little fluid.

I just did mine and about 1/2 quart was lost... the car was level at the time. U just need a new o ring to fix.

Ok, you're right I had the front of the car jacked up at the time. Jacked the back up and pulled the speedo and no fluid came out. The O-Ring on the sleeve is brand new though. I think the problem initially was to much Trick Shift in the tranny. Could it be possible that the pressure was so high that it leaked out of the new o-ring seal? Anyway, I reinstalled the speedo with a little petroleum jelly. I ran the tranny through all gears and checked the stick carefully and filled the rest up with regular old Dexron. Doesn't seem to be leaking now. The problem with that trickshift stuff is you can hardly even see it on the stick.
