trans/driveshaft leak?

[Rupesy]

I just can'seem to plug all the leaks on my transmission. Another one just showed up. It appears to be coming from the universal joint. I guess I can see how it could leak from here. Any suggestions? I attached a photo.

If the output shaft seal is not leaking, there may be trans oil wicking through the spline and leaking out the plug in the back of the driveshaft yoke. I've had a couple of them do that.



If you determine that's the source, you get to disassemble it and deal with it:

I had a leak in the yoke on my 92. There was a small hole that had been filled with plastic from the factory. Was able to melt the remaining plastic out with a torch, seal the hole with JB weld, reinstall the u-joints and have no problems after that.

I guess i should have searched before posting I cut a 1 inch round disk of rubber
and siliconed it internally in the splined shaft and JB Welded the outside

If it has the vented driveshaft yoke plug.
You need to remove the tail shaft and repair the oil ring in the stell sleve on the tail end of output shaft.
Sometimes on replacement transmissions the sleve and seal gets left off.
Some people plug the vent hole but I would not recommend it.
It puts whiplash on rear transmission output shaft if you do.
