Hello and goodafternoon,
So I was dricing back from the grocery store the other day and noticed my truck was shifting rough and the OD light was flashing on the shift selector. I plugged a few scanners up to it and no codes.
Brought it to a buddy and he plugged his 3,000 dollar snap on scanner and ran a code for P1728 torque converter clutch failing to engage.
After calling some places they told me to drop the pan and test the solenoids. So I did so, tested them all and the all the resistance was in spec.
Anyone know where I should go next? Ive been told to replace the TC but I do not want to drop the transmission and spend the money on the TC when there potentially could be something else I can check.
I have a 97 PSD 7.3 CCLB E4OD
Any help would be much appreciated. Thanks in advance.
