I love my 4.56s and 4L80

 

I went from 3.73 to 4.10 and it was rather uneventful. I agree with nonnie

 

Fyi. I went from a 60 with stock tc to a 80 with a 3600 tc and i only dropped 1mpg. I have always tracked my mpg so i was pretty surprised.

Honestly i have no idea why people complain about the gear ratios in the 80, if anything they are 10x better because they are closer together and longer.

 

Yea I agree. The 1-2 shift in the 60 is such a dramatic drop. 80e is definitely much smoother.

 

Ok guys have a couple questions what exactly else do I need for my driveshaft to hook up to the 80e

 

Th-400 slip yoke

 

It'll need a new slip yoke and a haircut...

 

Lol I see what you did there
