PO700 code
IPULLRV. I had the same code on my 03, the dealer replaced 3 corroded pins with gold plated ones the first time. The second time I got the the same code, the dealer replaced the TCM p/n 56040476-AE and wire harness p/n 56051861-AA. All is well for now, but I haven't towed with it since. That will come Monday when we leave for Tucson. Hope you get truck repaired ok. My truck would shift into OD.
