the truck still starts up, right??

erase the custom tune from the trinity....

go to Options, and it should be in there somewhere to Erase Custom Tune...

after you erase custom tune, then disconnect/reboot trinity, and try it on the truck again, in the order I listed above...

Lew,
Here's what we did. We installed Diablo tune. When choosing diablo tune, it asks you what tranny tune you want. The 3 options are Modify stock, Firm, and Hard. We selected modify stock and didn't modify anything. Then, Diablo tune was uploaded. Then, we brought trinity in the house and uploaded Lew Tune. Then, went to the truck. Same error of no communication. Here is the picture of the Trinity after initial Diablo Tune was loaded.

Thanks,
Tom

Hi Guys,
Any updates with making this compatible for custom tunes?

Thanks!
Tom

I seem to be having a similar problem I'm unable to install the TCM tune. It reads it fine but when i go to install the tune it only installs the ECM tune. When I modify the tune it gives me options to adjust the shift pressure but when I proceed with installing the tune it didnt program the tranny just the ECM and the trinity shows that i have the 87 tune installed and the TCM is the orginal backup. So do I just need to post up a copy of my TCM backup to get this bug fixed?
