No drive after tune install.

Boosted6.4 · Dec 23, 2015

Got GH race files from PSE (Great people, super helpful) today for my 6.4. The truck is currently in KEM 250 programmed from another tuner that was stolen. I have since purchased an x4 and had the GH tunes written for. After programming the race, the truck loses all forward gears, acts like a trans brake. Reverse, has harsh engagement but works. Before installing GH file the "Trans SWPN" was 7U7A-14C337-AD. After installing GH race the "trans SWPN" is 8C3A-14C337-DB. Could my issue be the tune is written for wrong trans code? Returning the x4 to "stock" aka the KEM file that was on the truck prior to tuning results in the trans and everything working again.

Or is my problem tuning over the original KEM file and using that as my stock file? I luckily still have my stock file from my livewire if need be.

All help is appreciated!

you have a Job 1 truck, and they're loading a Job 2+ trans file

it is not due to replacing the KEM file

Build date is 07/07, I thought that would be Job 2?

If you got the strategy off the truck with the kem tune loaded iirc it can show a different ecu stratagy from the tune. I had the same issue after my build because my stock fIle wasn't in when I gave Matt my strategy. He is the one who figured it out.

I found the email I sent to KEM a while back. This is the strategy off the stock file installed on the truck.

Trans-7U7A-14C337-AB
Engine-8U7A-14C204-CG

Would the wrong strategy cause the trans to lock up when put in drive?

You have a Job 1 TCM on the truck. Which would imply that it's a Job 1 truck.

Yes, loading a Job 2+ trans file on a Job 1 TCM is going to cause all kinds of problems

Yes, everytime. I have had several sct's loaded with both trans files if you accidentally load the wrong one it will act just as you described. I have done it a couple times.
