Auto trans won’t go above 6th gear

[Sticks702]

Any progress with this Sticks702 ?

I just got the OBDII Bluetooth to use with Jscan, delivered yesterday. I plan to mess with it tomorrow. Hopefully the Superchips FlashCal will let me return it to stock first. I was finally able to get the unit to accept their updated software so maybe that is the key! Fingers crossed

I was finally able to correct this issue. I got the Jscan and tried to reset the Superchips tuner back to stock. It would not do it. I had updated the software on that tuner recently, but on a whim, I tried again, and there were six additional updates. After the update, I was able to talk to the JT and reset to stock. Just for the Hell of it, I reprogrammed tires, gears, start-stop, etc., with it and drove it, and low and behold, everything worked as it should. I still do not trust it, so I reset it back to stock and did everything with the Jscan. It drives as it should now.

What? Did you even read the post?

Sounds to me like it needs to re-learn the shift points.

To his point, I believe a little more Hp/ torque would help. Relearning shift points should solve his issue. The larger wheels has the same effect as if you were towing a heavy load. You see much higher RPMs and rarely see the higher gears.
