if u can lock it with the scanner your system is fine. Did u try to lock it with the vcm scanner?

 

Thanks for all the help guys.

There is a Trans Go HD2 installed, so thankfully I didn't need to pin the valves (that'd be over my head)

Went over and over the tune and found nothing to keep it from locking. Plus, with the same tune, it was locking/unlocking fine.

So I went ahead and changed the TCC and PWM solenoids. Didn't fix it...at first.

Unplugged the battery for an unrelated reason, and just let it sit for a few days as I was disgusted with it. Tried it a couple of days later to see if I could get it to throw a code, and much to my suprise, it locked. Tune didn't change, so I'm guessing it was one of the solenoids.

Thanks for all the suggestions you guys threw out.

 

I'm guessing that after you got the P0741 you never cleared the codes. Good to hear that you got it sorted out. Vince
