What drive/driven gears for T5 & 3.42 gears?
T5 is going into the IROC soon. Will my drive/driven gears from my 700R4 work? If not, what gears do I need? Thanks.

No, the 700R4 and T5 use different gears. Stock for a 3.42 rear end and stock 245/50-16" tires is a 7 tooth purple drive gear and a white 19 tooth driven gear.

I'm running 255s on the car, but as soon as I get new tires I'm going back to the right size. These 255s have too much sidewall and look fairly stupid. Anyway, thanks for the info. I'll have to pull the VSS out and peek in there.

I'am running the 7/19 tooth combo on my car right now. My rear gear ratio is 3.27 and my tires are the stock 245/50, my speedo couldn't be more bang on then it is now, I also used a GPS unit to clock my speed and I was only 1 km/h fast.
Now from what people tell me and from a GM chart I saw awile back the stock combo for 3.42/3.45 ratio is 7/20 tooth.

From my info, which could be incomplete, I have:
Drive gears: 6T, 7T, 8T, 9T
Driven gears: 19T, 20T, 21T, 22T
For the 3.27 gearing with 245 tires, the actual driven gear is 17.99, or 18. But the 7/19 combo would give better breathing room for error, as stated before with the GPS.

NOS 5151 150HP kit
ProBuilt 700R4, PI Vigilante 2800 stall lockup
Baer Brakes 12" Sport System
Drive gears: 6T, 7T, 8T, 9T
Driven gears: 19T, 20T, 21T, 22T

my car came with a 9-bolt rear with 3.45s and it has the same combo 20 tooth green (light blue is what it looks like to me)and the purple 7 tooth gear.
