The Powerglide transmission in my 1962 Tempest Safari shifts into reverse and low but won't upshift to drive. The usual causes for this could be a stripped governor nylon gear, low on trans fluid, throttle kickdown lever or rear oil pump not working. After being unsuccessful at determining the cause I recently removed the transaxle so that I could open up the transmission and have a look. As I lifted the planetary gear unit out I heard something drop. There are 2 pins on this that drive the rear oil pump and both had come out because the holes were beat up and oblong.

I brought the planetary gear unit to a local machine shop and had them drill 2 new holes for the pump drive pins. I was able to re-use original pins and they now fit snug in their new holes.

Now I am waiting for clutch plates from ebay and gaskets, o-rings and bushings from Clark's Corvair. I will be re-assembling the transmission during the next week.

A few years ago I bought Kent-Moore tools needed to work on the automatic trans and differential. All tools shown are illustrated in the 1962 Tempest workshop manual.
I painted the transmission housing with Eastwoods Alumablast.
