Has anyone installed one of these in their 1999 to 2004 trucks ? Does it require an aftermarket computer?
I went to Holley Fest and my truck ran a couple 12.0 to 12.10. I thought it was the heat, but when i looked at the log it shifted at 3500 and 5200 rpm. Ran like a dog. I need a trans controller !!!
thx

Same issues i had with old tranny
definately an electronic issue. I tried swapping computer's and same thing for 3 years now.

 

I have an xtra 4l60e for sale.
i thought it was messed up but new performa built did the same thing.

 

What trans do you have?

 

As far as I know it's basically impossible to control a 8 speed or 10 speed computer without the factory computer and various other modules . The transmission is setup specifically to run on those torque based computers.

 

factory 4l60e built by 30 yr trans builder in Middleburg FL. He built trannys for Hardcore on here running his yellow GTO

Thx for info

 

There's 1 or 2 companies tht supposedly make a stand alone controller for the 6l80e. Cant think of them currently.

I do alot of ls swaps and i only use the 6 speeds with a engine/wiring setup thts 2007+ they need a e38 ecu and work off of canbus. These setups also need canbus interface gauges to work correctly.

I wouldnt even want to attempt to install one in an older platform. They are a lil tricky to tune as well. Way more tables than a 60/80e.

For your setup i would go 4l80e or th400. They will last, and hold up to what ever u put to them. I dont even bother with the 4l60e trans anymore. They never hold up and cost more than they are worth.

 

Thanks for info. This will probably be my last 60e.
I just ordered the US Shift controller. I contacted Performa Built and they also recommended that controller. We shall see how it goes.

 

PCS makes a stand alone controller and harness for the 6L80E/6L90E
TCM2650 MECHATRONIC TRANSMISSION CONTROLLER

 

i read about that one too. Not a bad unit
