2008 Tahoe--Trinity no help with tranny shift?

[Eric137bucs]

Hey there, and thanks in advance for the help.......I just bought a 2008 Tahoe 5.3L, and opted for a Trinity programmer. My previous vehicle was a 2007 Tahoe 5.3L, on which I used a Superchips programmer.
I am happy with the performance overall, but was surprised when I initially plugged in the Trinity to find that there are no options for firming up the transmission shift, as is available on the Superchips.
Is there an update for this? I just bought the Trinity last week, but maybe it had been sitting for a while???
I still have the 2007 Tahoe (since the lease still has a few more weeks), and the difference in the way the two vehicles shift is night and day, especially when accelerating during passing (35-50 mph).
Just wondering if anything can be done about this. I'd hate to think I spent a couple of hundred dollars extra over the Superchips and have to live with the shifting the way it is.
Thanks again
Eric

nope, no tcm/tranny support yet...

however, you can buy a custom tune to really wake up that truck, and there is stuff that can be done via a custom tune in order to improve the tranny shifting very nicely...

but no, you can not do it yourself via the handheld unit...

Buy a custom tune through Diablosport? How do I go about doing it?
