Default Re: 1951 Ford overdrive

The transmission is back together. There were 3 things that were wrong or incorrect. As I mentioned previously the plate which covers the Balk ring and gear had a significant ridge worn into it which prevented the pawl from fully engaging balk gear and thus preventing the shift into overdrive. The damage to the speedometer/governor gear was caused by an incorrect governor drive gear assembly. The tip of the unit measures 0.248 and should have been 0.375. The recess in the OD housing measures 3/8" or 0.375. This allowed the gear to move abnormally and resulted in the damage to speedometer / governor gear. The replacement part is being shipped. I wan't to again thank everyone for their help and interest, with special thanks to Gary Duff.
