Im working on an 05 GMC 4500. It sets the following codes when pulling a trailer with a skidloader on. P0741 TCC circuit performance or stuck off
p2764 TCC pressure control solenoid control circuit low
p2761 TCC pressure control solenoid circuitl open
Ive checked the circuits from the TCM to the trans connector-ok
I dropped the pan and commanded the TCC solenoid with my scantool-ok
measured resistance of TCC solenoid-ok
Reinstalled pan with new internal filter and bushing. Refilled and roadtested without a trailer. No codes and trans shifted fine. Codes reset two days later when pulling trailer and skidloader. Ive referred to the tsb about the stator shaft rotating in the pump housing???? any input would be great? thanks guys!
