I just posted this message on Corvair Center.  

I decided to replace the noisy transmission (pitted gears, bad bearings) on the 64 Sagan Spyder that had less than 50 miles on it since I restored the car. It had new Clark's blocker rings and syncro dogs.  I found another transmission with good gears and replaced the countergear shaft, all roller and main shaft bearings, and removed the new blocker rings and syncro dogs from the original transmission and put them on the replacement transmission.  This was a nice looking transmission.

The problem with the replacement transmission is that the third gear blocker ring is sticking making shifting into third gear extremely difficult (until the blocker ring frees up). The the shift is very rough due to the pressure on the shifter to free the blocker ring.  There is no gear clash.  I noticed this problem (sticking third gear blocking ring) before I installed the transmission but had fairth that it would free up in use.  Wrong!  Clark's said to just drive it, but the shift into third is so rough that I am afraid somthing is going to break.  The gear oil is NAPA 85-90 GL-4.   

Anyone else ever had this problem?  What can I do about it?  Help!!
