I think the up shift points are a little high, even when not in tow mode. I've been thinking about doing a Transmission & rearend service this winter. I have read up on the transmission and seems like they use a special fluid. I've been using AMSOil in my other trucks and was considering making a change. The truck had a Quaker State
Sticker on it with mileage for changes. I have used Q-state on all my changes. There is a little more oil consumption than I like...Thinking about making a change and see what happens.

Adger,
I had mine serviced and flushed recently and switched to the Transynd 668 fluid.
The shifting improved dramatically with smooth and firm shifts.

There?s a place in Perkasie Pa that might do it.
That is not far from Maple grove I think.
I?m not sure the would do a shipped in ecu though.

I used Rocket Chip on my 8.1L motorhome. Saw improved torque and throttle response. $99 and plus into the OBD port very simple.
