don't do it

 

Jake's has a 6 pinion heavy duty 2.75 ratio gearsets for $1000 additonal on their website. Don't know what the second gear is in their set.

 

i guess everbody has a different look. but i know 3 guys with 2006 and newer turdo vettes ,camaros and they have 6l80 trans and the gears are 4.02(1st) and 2.36(2nd) gears and they are putting good number up at the track .i was thinking theses cars are lot lighter than my truck and they are geared lowered

 

What rear gears are they running?

 

3.08 /3.42

 

Yes they do work with the 6l80/90 but they have like 2.56 gears stock

 

You can run th400 gears in the earlier 4L80Es (later 4l80es too using more early parts). You just have to press the reluctor wheel on for VSS. With that being said, you can get them in 2.97/1.57, 2.75/1.57, 2.10/1.40, 1.95/1.35 1.86/1.29 ratios. There are others, but these are more common.

 

2.97 1st
1.57 2nd

What's 80e stock?

 

Stock 4L80E:
1: 2.48
2: 1.48
3: 1.00
4: 0.75
R: 2.07

 

My first gear is completely useless just like the 60e. I like the 80e gearing alot better.
