[T3] 2026 Invasion Updates...

[Jim Adney]

Keith,

I understand that this is a fresh rebuild. So what was changed? From your 
previous emails, I'm guessing that you got a new 4th gear set and maybe 
new syncros. The other thing that changed is the assembly.

All the other parts are the same, but they are just a bit more worn now. It 
seems unlikely that this tiny bit of extra wear pushed things over the edge, 
but it's still slightly possible. If there's wear in the 3-4 shift fork detent, that 
could also do it, but I don't expect those parts to wear.

There are 3 lugs that hold things in position. They are pushed outwards by a 
spring. I suppose the spring could be weak or bent, or the lugs could be 
worn, or the thing they lock into could be worn. I'm now past my level of 
understanding. I should look at some of those parts again. Should I bring 
some to the Invasion?

The other thing is the assembly. If the 3-4 shift fork is slightly misadjusted, 
that would do it. That has to be redone on each reassembly.
