[Fot] Racing a Triumph TRANSMISSIONS GT6 REBUILD

[Bill Tobin]

Just got back from the Glen; pretty nippy but nice.

re: transmissions: SVRA's  Jack Whoerle (sp) told us a couple years ago that 
because OD's were used in the day, we can use a 5 speed gearbox, but 5th has 
to be less than 1:1. Other organizations will tell you the same thing.

I've used the same gearbox for 6 years now with no problems. Yes, I run 
towards the back of the pack, but always have someone to dice with. And I'm 
having a great time. And not spending a fortune doing it.

The "Redhead" has had a total of 2 DNF's in the 6 years of driving it, and 
they were in the first 2 races I ever did. Not bad.
My $.02 worth.
Cheers, Bill
