hey man i got a question for you. i got a buddy who has simuilar HP goals for his SS and he is looking for a tranny, how would you reccomend finish line transmissions. i dont think the switch from a 4L65E to a 4L80E would be too difficult losing the AWD of course. any thoughts?

I can recommend FTL based on the customer service and track record, They built Parish's tranny and it has held up to hundreds of 1/4 mile passes.

 

shouldn't be to much longer for mine to fire up. Right now Rick is working on swapping out my AWD T-case for a Two wheel drive unit so he can get it on His dyno, the AWD T-case will be going back in after it is tuned.

so you can run AWD with the 4L80E? i didnt know that.

yep, you just need to get a new input Gear in the Transfer case for the 4L80 160.00 dollars

Or you can get a different Transmission Shaft,

Chuck from FLT recommended to do the Input gear on the NVG 149 because it is stronger.
