Hey everyone, i'm on my third tailshaft seal and i can't get it to hold. Slip yoke is smooth. fluid level seems to be fine.

I can throw a new seal in, putt around in the drive way,putt around the pits. its fine. After i come back from a pass there will be a circular spray pattern in the trans tunnel.

Some ideas would be greatly appreciated. - Joe.

Does the yolk have a hole on back side?

Bad brand of seal?

Worn yoke or tailshaft bushing?

Incorrectly installed tailhousing?

Bent tailshaft due to some racing abuse?

thanks for all the replys. I'll have the drive shaft checked on monday. should the bushing be able to move relatively freely? mine does, i wonder if its walking back under high rpm...

i'll check the yoke for holes.

i'll pop the driveshaft out and look this morning.

Thanks

The yoke should be able to slide in and out somewhat freely, but should not have a perceivable up and down (or side to side) movement. If so the bushing or yoke is worn.

The bushing moves?:confused:


The bushing must not move, period. If it does the return hole is being cut off.
Get a different housing.

i don't know much about the technical stuff with a c/4 , is the return hole at the very end of the housing by the seal?

when i took the seal out i saw three rectangular shaped holes in the end of the housing. there was a thin metal bushing protruding 1/4" or so out towards the seal.

But does the bushing move?

It shouldn't stick out that far, by the sound of that the return holes are being cut off.

yes it will move forward, when i first got this trans the bushing stuck out so far it would interfere with the seal. so i tapped it in, sticks out a 1/4 inch now, i could probably get the bushing even with the face of the holes...

Pull the housing and install a new bushing or different housing.

You need a BFH to install the bushing, not a tack hammer.
