Ok,l i (had) a 4l60e that i just recently blew. im trying to decide if i should buy a new 4l60e from gear works thats built for 500 horse with a 3200 stall in it or just have mine rebuilt for racing but.. in a few months im putting a 6.0 in it so i was wondering what would be the best way to go Built 4l60e or stock 4l80e... will the built 4l60e hold up on the 6.0
Thanks
gm sold them together from the factory that way, but when you start making horsepower they tend to be the weaklink in your setup. i would say this is the time to swith them out. it all depends on your driving style.
4l80e FTW
well i race alot lol but dont we all :burnrub:
Get the 80e. GM knows the 60e is weak and even puts the 80e behind 4.8L engines in work vans.
My built 65e is doing great behind a cammed and boosted 5.3 i guess it's the luck of the draw.
If i do an 80e will i have to but the wiring harness and stuff
Its actually not that bad. Click here.
All you need to do is change some PINs around in the passenger side circle connector and add an extra VSS (ISS) wire to the PCM.

Dont waist your time. just upgrade to 80e now, and save your self the headache of blowing a built 60e. :chevy:Quote:

I was told ill have to change my crossmember and wiring harness and drive shaft is this true or what
change xmember, rewire the transmission connector and swap to a TH400 yoke. You'll also need a new tune setup with the 80e programming.
You can buy a crossmember for a 80e swap, or just get someone to cut more the center of the crossmember about six inches i think. then weld it with 1/4 metal extensions.Quote:

Ok would it be to hard to change to A 5 Speed i found a totaled RST that i can get everything from to do the swap
If you want your truck to shift like a tractor then go for it.
would it not be better for street racing]
No. Just stick with the 80e swap. You'll be glad you did it.
i was told i will lose alot of horse power when i do the swap and i was told there are alot of electrical problems with the 80e
First off. Many have done the swap and their times have gotten better because of the ratios. Second off, even if the 80es had electrical problems think off ALL the problems a 60e has
60e = Junk
80e = Reliability and Strength
true im just tryin to make sure i make the right decision i think im going to pic up the 80e wenesday
OK i got the 80e can anyone tell me the web sit to go to to get the harness addapter and crossmember
You can do both yourself if your good at wiring and welding. Or Nelson Performance can make you the harness for under $100 and Pact can do the crossmember.....Or kyle at kbracing who is on this site.
well im a cirtified welder and i do my own wiring so i think i can do it myself
Theres a thread on performancetruck.net with a full write up on the wiring.
ok i got a 4l80e with 90,000 miles one it should i have it checked out before i put it in
You just have to remember the 60E is not weak.
Its just a car trans, that GM put into a heavy ass truck that
was never intended to be flogged on.
You'll be happy with 80E I'm sure.
The center section moves to the rear 6 1/4 inches on a 1999 to 2006
Dropping then pan and looking at the fluid, screens on the solenoids, etc can tell you a lot. IF anything, just a new filter and fluid change will be enough.Quote:
