A bone stock 4l80e will hold.

 

nope you lose to much torque threw a 80 im confident with the 60e im gettin to much bs you gotta do to convert to 80e

 

Good luck.

 

+1 on the good luck, i have just read too many threads that start out "well i got my radix in today" and the next week "i got my built tranny" and finally "intsalled my 80e"
these are just my observations, i know your set on the built 60e but you might want to sell the 60e and put it towards the 80e.
keep us updated

 

Exactly it might be a little more work installing an 80e but then youre done with it and they shift so much faster (not harder) then a 60e I have no regrets I absolutely love it.

 

If I had a 2wd I would already be sporting an 80E. As it is now I will try and keep 2 65E's. Built one in the truck and a spare when it blows. I'm running my spare now and the built one is sitting on the floor needing to go out for repair.

 

Sounds like me with motors. Built one in the truck and a spare built one in a friends garage.

 

How can it shift faster, a 4l60e has a 3.06 1st. Due to tighter spacing?

Read Ky's last sentence again...the BUILT one. I only like the 1st of 60E & lighter weight, that's it. + I have my stock core for now ( soon to have ) that'll give Vince. For a 4L6xE. I'll see, or...

Only 4L80E downsides. Heavier, 1st Gear, driveshaft work & no core. Oh, wiring & dinkin w/HPTuners to run it. Still gotta learn that too.
Upside: NO WORRIES!!! since it's not a. I usually overbuild, why not, its just $. OVERKILL on builds = no worries.

 

The amount of time it takes the shift to happen, not the gearing or the amount of time it takes to get to the shift. I said Faster (not harder)

 

truck sounds sweet bro
