how much is the shaft?? thats one way to find out some one buy it

 

How much more power/torque does the 4L80E consume versus the 4L60E?

Thanks,
Kevin C

 

so to go from a 60e to an 80e in a 4wd not SS you need a new flexplate, crossmember, harness, TC, and shorter drive shaft. what else am i missing? also would you would need the transfercase, or swap out some shaft in it. im just think about going to an 80e and not have to deal with the tranny anymore. i would like to have a 408 and some n20. and be dune with the engine aspect. a local junk yard has some 00 and 01 80e trans for like $650 not sure about how many miles though.

 

in 2002 did they start putting the 65 in or was it in 03 or 04???

 

Related to TheLadiesMan's (Leon Phelps??) question, how many of the necessary parts for a 60 to 80 swap could be snipped off of a 2500 or 3500 truck?? Like, would a 2500 crossmember bolt in to the 1500 chassis, or are the frames different (in shape/spacing)?? My truck is 4WD (I guess it's autotrack... has an "auto" mode for the 4WD on the dash), so could I get a 2500 front driveshaft and shorten my factory rear piece (read: getting a driveshaft shortened/balanced is only ~$80 vs. the cost of a whole new shaft)?? I would think that the wiring harness pigtail/adapter would be easy enough to make with a couple of connectors and some pin-out diagrams. As I understand it, all that would be necessary in order to retain my current transfer case would be to use/install the piece from Transmission Exchange that was mentioned in the first page of this thread... is that correct?? Would my current transfer case be strong enough to deal with the kind of power that would require a 4L80E??

Leaning towards eventually doing a mild turbo 408 (not looking to go racing, just want to have something that'll be fun around town). Thanks for any input.

 

anyone?

 

the 65e only comes in certain trucks as the escalade and ss if i remember right. oh yay i think the denali's got it to. 01 or 02-not sure on that. go 80e. i did and i am glad i did.

 

I Am On My 3rd 4l65 And Done Had 4 4l60 In My 01 Truck I Did Not Have A Trans Cooler On It Until I Put The First 65 In I Have Try The Red Eagle Clutches And Stock Clutches Now I An Trying Bourg Warner Hp Clutches With A Red Eafle Second Gear Band I Had A Vette 1 -2 Shift Srevo With The Trailblazer Converter With All Other Trans Except This Last One Was A Ptc. Now It Will Have Ptc Converter Trans. Go Kit Billit 1-2 Servo With Someone That Also Is A Racer That Owns He's Own Shop He Knows Some Tricks To Get The 65 To Hold Up We Will See Wednesday Or Thursday Truck Went 12.72 @105 With It Slipping Into 3rd Gear With A 60' @ 1.65 Launching @ 2000 When I Get It Back Together Trans And I Am Putting Heads On It I Am Going To Be Launching It At 2500. I Put 5.7 Valves In 5.3 Heads And Shaved Them .35 Ths ,open Combustion Area To Let Valve Work Better Smooth The Exhaust Runners And Combustion Area
