No. Double checked it just to make sure now that you mention it. 1-2 shift is set at 35 mph. Going to try dropping that down... To me... it seems close to right... but the ECU/TCM is funny that way if it thinks theres going to be an RPM overrun. I've seen this mostly in D mode with WOT downshift if I have the shift mph too high. This looks the same to me... just in 1st. I think this interplays with the

I'm thinking it's got to be either that or it just needs to learn that shift by doing that a couple more times. I'll just try dropping it down several MPH and just retry the next time, then creep it back up if its gone.

It may also have something to do with this table... but I haven't wrapped my head around it yet. I think it was this table that was discussed in another thread regarding rpm limits and not allowing enough torque. I think these values are triggered when the ECU thinks there's going to be an RPM limit overrun.
