Hard Downshift from 2nd to 1st
Hello Peeps!
My truck has been doing an abrupt jerk while downshifting from 2nd to 1st at approximately 2-3 mph when coming to a complete stop. It only happens when light on the brakes coming to a smooth stop. The truck jerks right when it shifts down into 1st just before coming to a complete stop - sometimes more extreme then others. Under moderate to heavy braking, the deceleration and downshifting is normal.
I don't know if this is a tranny issue or if my Edge messed something up with my truck's ECM?
Suggestions?
Thanks all!

1. Completely different tranny
2. Completely different calibrations ( his is also canned, yer was custom )
3. OP has a separate TCM - you do not.

It was worse on the canned. But my point was I see that a lot with the edges. Some trucks have issues with the shifting.

I converted back to Edge Evo CTS a week ago, while still running Stock mode, hoping it would positively impact my issue to no avail. I am running nothing right now and still have the issue, so maybe flashing the ECM is what I might ultimately need.

I have an appointment this Saturday at my local Ford dealership. I will post the outcome.
