5.3 turbo plus 4l80e what gears?
Hi all, Just looking for a little input. I have had the 5.3 in my truck for about 11 years now. about 5 years ago I did the turbo, I had the 4l60 with 3.73 gears for a short time with that but the converter didn't like the turbo so I swapped to a T56 I had and added 4.11 gears with the double overdrive.
I am now on the final (hopefully) trans with a built 4l80. I need a gear change. Any thoughts? I could go back to the 3.73 but that doesn't offer much from where I am. I need to confirm which carrier I have to make sure what gearing I can support as I don't want to change that. the truck 12 bolt has factory 3.08 gears but there maybe others that can be found. Any thoughts? I do like to drive this. My last long trip was tough with the 4.11 and the 4l80 but I was in a time crunch and couldn't make the change. thanks Dave
