When SilverSport shipped mine, it came with a standalone controller for the Transmission from F.A.S.T. EZ Tune.
I believe they told me mine also has the 2.76 First Gear if I remember correctly. It’s been a while since I’ve had it in there, I would have to go back and double check.
On my setup, the TPS has to have a minimum voltage of .5 reading before it opens, in order to tell the system to activate. Might want to check that to make sure you have the minimum voltage and then go back do your setup.
My setup was pretty straightforward… I told it my speedo output pulses, gear ratio and tire height and then let it calculate and then turn off the key and go drive it.
My trans has 3 switches, I can do a Tow Mode, Performance Mode and then Manual mode (which I use the Paddle shifters for)
The TCC mode you referred to is the same as Tow Mode on most cars or trucks, you can turn it off or on to suit your needs… you can also adjust it to where it will not activate at either a certain RPM or MPH depending on your software.
It took some setting up and tweaking as it does with most computer controlled systems. They’re not plug and play like they lead you to believe.
Hope you get it sorted out! Once you do, you’ll love it!
I have a mild 360 w/3.55 rear and 26” tires and I get about 16-17 hwy and that’s cruising 70mph @1800 rpm’s running the AC!
