i had both billet servos' + tru cool40k cooler ,and this was the outcome =

 

Alright thanks

 

I was only making around 320 at the crank when my 60E slipped. Granted it had over 190k miles on it and to my knowledge it had never been rebuilt. The 3-4 clutch pack went and then I got the over run clutch too from driving it around in 3rd mostly relying on the over run clutch which is only two small plates. 1-2 was still pretty stout though with just a servo. Found a 4L80E for a bargain and have never looked back.

 

Definately...these are a must if u plan to stay with the 60E. Some guys have had great luck, but its a fact that ur on borrowed time. EVen a level5 built 60 is really only good to roughly 400rwhp.

 

So I assume that the 80e is a bigger tranny. That being the case would you have to get a different driveshaft? If so, would one from an 80e work in a half ton?

 

80e requires new TC, trans, tune, crossmember, and a little wiring, driveshafts

 

I put my 60e threw tons of abuse . . . Shift kit, plate, servos, stock cooler, stock TC

I've pulled boats . . . heavy trailers . . . didn't matter

 

Agreed...works great...in some cases, but cant handle any kinda big torq #'s.

 

still running my stock 65e (shift kit, servos, converter, and cooler)

 

How much power are you making??
