The Stovebolt Site Forums The Shop Area Driveline power glide prob

I have a 56 bel-air with a 283 hooked up to a power glide. I have started noticing a puddle of trans fluid on the barn floor back where the trans is connected to the drive shaft. Could this be a rear seal going bad? Have never worked on a powerglide before, can the seal be replaced in the car or will I need to drop it out. Thanks for any help guys.

The seal can be replaced in the car. The driveshaft will have to be removed. The seal is a common part available in most parts stores. That may not fix the problem, however. If the rear bushing is worn the seal likely won't last very long. The rear tail housing of the transmission will need to be removed to replace the bushing.

Snap-On makes a bushing puller/installer that can be used with the tailshaft housing in place, but very few shops have them. It has expanding fingers that can be slipped through the bushing with the driveshaft removed, then an internal sleeve is slid into place to expand the fingers. A few taps with a slide hammer removes the bushing, and the same tool is set up to drive a new one into place. A well-equipped transmission shop should have that tool. The high school auto shop where I taught for 30-something years had a set of those pullers.
