Before me, I have a very toasty and well used C6 behind a code H 390.
I want to do a good build on the C6, and have been wondering what
peoples' experience has been at using an AOD (or equivalent) front
gear set in a C6 to give a 2.78 first vis à vis 2.46. I understand
it's a "drop in" mod but the valve body has to be worked at bit
(softer 1-2 and 2-3 springs) to get the shift points right. Anyone
done this?
If so, and furthermore, has anyone replaced most of the thrust washers
in a C6 with Torringtons to reduce drag? I hear that setting proper
clearance can be tricky and that while lessening drag, the Torringtons
have a finite service life.
I've talked to local shops, and I usually get a blank stare when these
ideas are posed. 'Net sellers gladly hawk the parts, but give a
paucity of info.
All comments welcome.
