i cant find a file for hp tuners to flash over ..... 07+ trucks dont come with a 4l80e


is there anyway i can manipulate the computer t0 make the 4l80e work in my truck?


if not im going to have to run a 6l80e and im not to happy with that

 

here is your tune

 

apparently its not to hard to get working. the new vans still come with 4l80's so you will need to get a tcm with the van info loaded on it. im no tuner so im just passing info on to you. check out this link though and the OP of this post has his truck running with the 4l80e https://www.performancetrucks.net/fo...d.php?t=454364
let me know what you find out because ive already ordered my converter

maybe justin from blackbear will give some insight on this also as he told me he will get it working on my truck

 

i pmed redheartbeat. i may go take a van from the dealer on a test drive, let allen snag the tune file off that bish!!

 

haha sounds good. or just take the tcm without the test drive.... let me know how you make out and any surprises you may find

 

I'm pretty sure the vans don't have 6.2's with 4L80's. The 6L80e TCM is on hi-speed LAN, if it's not hooked up your going to run into alot of communication problems. Whats wrong with the 6L?

 

the newest vans 2010's now have the 6l80 or 90 im not sure but definately in 2008 the 2500 and 3500 cargo vans came with either a 4.8 or 6.0 backed by a 4l80

 

I understand that. But if you program it, it still won't be able to control it. The ECM has no way of controlling the transmission. When you ditch the 6L80e you are also ditching the TCM. Your probably going to have to change harnesses and use PCM for a 6.0/4L70e, and then modify from there.

 

i got what your saying. maybe we werent on the same page. daryns truck originally had a 4l60e, it never had a 6l80 in there like a lot of the newest gmt900 trucks do.

 

4l70e the 4l70e's come with an ISS like the 4l80e ....if im correct all i need to do is pull the pins for the ISS out of the round plug and pin them to the front of the trans.
