I wondered if anyone has experience (good/bad) of these new 5-speed trannys? I'm thinking of fitting one (road-race ratio, so .82:1 5th, and running a 3.31:1 axle) to my 68 Iso Grifo 7-Liter. This will be strictly for road use, with the occasional 1/4 mile on the strip, just for fun. At the moment I have a Super T-10 4-speed with 2.88 rear.
I've read some adverse reports of the TKO600 on another forum, but these guys were slam-shifting at 7000rpm on the drag strip...

Cheers,
Chris
