Message: [QUOTE="mandkole, post: 1224019, member: 4630"] I drove the truck briefly with the chip unplugged. The trans shift points were a little earlier, 3rd gear TC lock on time, but in top gear/TC lock, the PCM signal would erratic unlock/lock like before. Its not the chip. The day I blew the ATF out of the plug and inspected the harness, then drove it for 10 miles or so it performed correctly under all conditions. The next day I drove it, back to the incorrect behavior immediately after getting on the interstate. This isn't high quality troubleshooting, but it makes me think its the pack. There is nothing in the lock switch wiring that appears failed. Its been there for years and the harness is in excellent condition. The switch performs correctly. Im thinking now I may need to verify if the TC is fully locked when the switch is on. Given that it runs at 150-155F on the interstate, it seems that it is. The heat builds quickly if its having trouble locking. [/QUOTE]
