Trans code P0720
So just got a new pcm installed since i fried the last one anyway
i had a new trans installed almost two weeks ago factory 4r100 now i have a p0720 code. Id take it back to that dealer but id rather put fireball in my *** so im just going to fix it myself
I cant seem to find a part price though for the sensor or some trouble shooting things to do before buying another part since ive had my truck two days in the past month,
EDIT if i woulda searched more i found a price at advanced auto.. but id like to trouble shoot before i replace

Ill check that tomorrow after work, The Over drive light only flashes once it shifts for the first time after being started .
process is Start , revs to 2krpms then shifts from 1st to 2nd, OD light flashes then it shifts smooth and fine after that .
I drove it 3 hours from PA to DE the weekend i picked it up with no issues just dont get how the dealership who did the install wouldnt of noticed it
