Dave,
Not a simple question...and I am not the expert.
I have a TR6 transmission in my garage on the floor that has been worked over
three times.
I will be going into it for a 4th time, for hopefully a final fix.
Frustrating, because I ran for several years with a transmission out of $75
parts car with no problems.
Frustrating, also, because it is very distracting on long winded tracks like
Road America. Popping out of gear indirectly caused terminal damage to our
engine. First catastrophic engine failure in 14 years.
Obvious Stuff.............................
Check all of the specs in the manual
Replace all worn parts
Check for bent sliders
Adjust detents within reason.
Now, I have a document from Jon Wood of the UK, discussing the tooth
configuration on the 3/4 synchro hubs....early and late configuration.....
Also he says "dont use the flanged washer...use the later type.....or grind
the flange .040."
"Can also get hub spring preload spring shims from Moss"
I have not studied this and his hand writing is hard to read, but I will
share any information I have or acquire in the future.
What I get from Jon....is that certain combinations of poorly engineering
designs, coupled with wear, screws up a perfectly good transmission. After
working for years with engineers and manufacturing folks, I understand how it
happens.
(The transmission that ran flawlessly for me for several years was out of
TR4A IRS car. It apparently was very low time. I miss that transmission.)
Again...no expert in transmissions here. I will forward my Jon Wood
response to you in a separate attachment.
