Hello, Joe. Sorry, it's been so long. I stupidly decided to try a used PCM, after the pinpoint test that I thought was telling me I wasn't getting power to the TSS. Of the three pins on the sensor, the reference voltage was suitable, but the middle pin was supposed to have power as well, but I was getting no reading. Ford says to replace PCM. I thought I checked the wiring to the best of my abilities. So, I got the new computer installed and started the vehicle, after warming up for over an hour and doing some shifting, N, R, N, D, R, D, N. After the fluid reached a temp of 160F, I put it in R, waited probably 10 seconds, and gave it a little throttle very slowly, a pretty loud and painful clunk is heard. I turned the Ford off and came into the house, frustrated and defeated. In retrospect, had I not been so frugal, I could've bought a used tranny with the money I'd spent. So, I didn't mention that the solenoid strategy and body id are not up to date. I did buy a VCX Nano J2534 tool, so I could update the strategy, just afraid to spend more money. I guess I would have to pay $50.00 for 2 days of access to update. I've read articles in the transmission digest available online, stating that some garages weren't doing these updates with minimum drivability issues after doing a couple of drive cycles. I think I'll take the front cover off again today, and try doing more electrical testing again. Are you still thinking it's a wiring issue? Thanks in advance. Jon
