What are the gear ratios in that trans?

subeone

4.027 2.364 1.532 1.152 0.852 0.667


So theres no true 1:1 gear but trans keeps burning up if it goes into 5th with converter locked or unlocked owner wants to go to a 3.08 gear so he can stay in 4th with converter unlocked a little longer and lengthen the life of the trans

Man, I didn't realize how steep that 1st is. That doesn't even seem useful, even in a stock daily driver situation........unless like you say, the rear gear is long as ****.

Badass. Im running mid 11s pulling 1.52 60ft with that first gear, 4.10 and a 30" radial. Looking to get in the 10s on a stock 6L90.

Subeone, what is the tire set up, wheels look good, btw do you do the tuning or turbo installs. THANKS!

subeone

@blown, yea the truck spins on 1st, ill see if i can upload a video.

@fillpot, fronts are 17x7, 28" tall tire rears are 15x10 with a et pro 30" welds s77, and yea i tune a lot of turbo stuff here in houston, TX. I don't do the installs, the shop I tune for handles that.
