<VV> Sticking Blocker Rings

[Jim Becker]

I've never run into that problem.  This suggestion may be a terrible idea, 
but here it is anyway.  You might try draining the transaxle oil and 
replacing it with CaseIH Hy-Tran oil.  Hy-Tran has additives for use with 
wet brakes thus may help the blocker ring behavior.  LaPorte in Westfield 
should have it on hand.

Does your housing have a drain plug or do you have to do it the hard way?

Subject:  Sticking Blocker Rings

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!!
