tranny ??? 4l80e
 

so are all the conections as far as wireing the same? i am thinking when i get a tranny i will try to make a 4l80e work. because i do not want to keep rebuilding 4l60e's

Re: tranny ??? 4l80e
 

No they are not. It takes a few wiring mods and PCM reprogramming to do it. Then it works fine.

Re: tranny ??? 4l80e
 

where can i get the info to do this? who can do the reprogram? will ls1edit still work? i know they sell a stand alone controler for the things but they are like $1000 or so, this route sounds cheaper and cleaner/ more simple

Re: tranny ??? 4l80e
 

Here's a idea. Get the flash from a 1500HD with a 6.0 and 4L80. Then use edit for the engine... Should work right :confused:

Re: tranny ??? 4l80e
 

who knows if it will work, i am a little afraid to just try it. someone else try it!!!

Re: tranny ??? 4l80e
 

i will but not soon enough for you. my plan is well i need money first. but i want to go buy a 4l80e from a wrecked truck or something not spend much. then have it built and eventualy take a weekend to figure out how to make it work. then i will have a 4l60e just chilling in the garage.

You guys ever thought of getting an engine harness from a wrecked 1500HD/2500/2500HD with a 4L80E behind it...

Re: tranny ??? 4l80e
 

Here's the 4L60E to 4L80E adapter kit we make for $150. It includes the main trans harness adapter as well as the ISS harness which must be added (and the 2 pins plugged into your PCM).
If you have LS1 Edit already you use a 4L80E file with a matching segment #1 ID. If you don't have LS1 Edit we can reprogram your PCM with the 4L80E file. It's actually better if you have Edit, so I don't have to get involved in a bunch of mail order tuning! :D

When doing in-shop harnesses we just build the harness for which ever trans is being used by the customer, but this adapter will do the same thing.
