driveshaft trans leak

[FoxGT87]

okay so i have had problems with the rear housing of my transmission leaking fluid, i thought i had it fixed. i replaced the yoke on the drive shaft, the bushing inside the rear housing and the seal of the rear housing. it stopped leaking for a few days and now i have a small puddle of fluid in my driveway again.

the last yoke was bent... crooked... messed up. i am sure it was from the torque being layed down to it. so yeah i have been doing some hole shots and having fun with the car off the line and generally enjoying myself with it. my question is, is this common i am probably only putting out 275 horses, i had help from a member and i think i have 4.30 gears. does this happen do i need to get a stronger driveshaft? could it possibly be something messed up inside of my transmission that is causing this? i plan on replacing my gear box with a better used one but i dont see that having anything to do with the rear housing seal leak.

i have already spent 110 dollars on this issue and its been less than a week of it being fixed. last time the leak was causing the fluid to get tossed onto my exhaust and my car would smoke everywhere i would go. i really need to get this taken care of. any suggestions or answers would be very much appreciated.

Man I hear your frustration, I've fought leaky output seals on my own car along with some customers. What seal are you using the standard seal or the reverse cup that extends out? I have success with both, but I know Tremec prefers the stock like reverse cup seal.

They can be very fragile, make sure it is lubed very well when you install the shaft. How is the driveshaft alignment? Driveshaft angle, do you know what the pinon angle is? If it is rotating a lot during the hard launches it could be causing a leak.
