I am getting a new shifter. But not till May this year. The cook and I are coming to America then. I was looking at the Summit racing brand shifters. They seem to be good value for money. Unless I find a new one at a swap meet before I get to Summit.

i was just reading about this on another site make sure the 80/90 your using is GL-4 AND NOT GL-5 gl-5 is corrosive to the syncros

On the back of the oil container it says it meets or exceeds these
SAE 80W/90
API GL-5,MT-1
US MIL-PRF-2105F
Mack GO-H
So I'll go to the store tomorrow and look for some GL-4. And give that a go.
Are there any additives that would be recommended for a Muncie.

heres the site from which i found the info,

If it is dragging coming out of gear, it is most likely the clutch not disengaging completely; there must be some way to check it for proper clearance. Synchros would mess with the re-engagement of the gear but not dis-engagement, unless the synchro teeth are messed up; if it is just the brasses, they will not go in without a double clutching, or grinding. 80-90W should be right; I don't know about the corrosive thing, though.

The problem with checking the clutch clearance is the bell housing is a Lakewood racing unit and it dose not have any inspection ports. I could use a 1 inch hole saw and put a rubber bung it after. How much clearance should there be ?

Since you seem pretty confident that the clutch is disengaging it may be time to start looking further into the tranny. Pull the side cover back off and see if the shift forks are bent, or the bushings in the cover loose. Who knows, the main shaft could be bent or other internal damage could be causing these issues. Might be time for a teardown.
Good Luck

That's not what I need to hear.

I do half of the cooking. And she knows that I love her. Some times you've got to try to get a reaction. Try this one at home next time they mention Tiger Woods on the news say ( That poor guy just leave him alone )
