ICP sensor VS hard shifts

Call me crazy...

But recently my CE light came on, shifts got REAL harsh (limp mode), and the EEC spit a code 1280 (ICP out of range, low)

When i got it home, the truck was idling real rough, so I unplugged the ICP.

Ran fine, but low on power, and the trans was still hitting hard.

Replaced the sensor..... rough idle, CEL, low power, rough shifting FIXED! :hehe:
