Jeep wrangler JK Unlimited 2013 with auto transmission.
I have read many topics in the forum about this issue but did not get a clear idea. Apologies if this has been answered before.

As you start crossing higher RPMs of 4500 and if you are in 1st gear (manual triptronic gear mode), the transmission automatically shifts to 2nd gear, even if you have manually set the triptronic to 1st gear. This is the default factory behaviour and i know it is meant for the engine/tranny protection. But i wheel my JK hard in the desert and when climbing steep sand dunes i need it to be in 1st gear and not automatically shift to 2nd. Else i lose torque and momentum at a crucial time. I need to be able to hit and hold 5200 RPM in 1st gear. I don’t need to go beyond 5500 RPM generally.
Is this possible through Trinity T1000?

Regards

there will be an update to add TCM control in the future, no ETA just yet.

I believe there has been now an update that this is possible with custom tune. The tuner thing should follow soon.
