Message: [QUOTE="Layson, post: 1227282, member: 298"] That sounds so much like what mine started to do. Then it progressively got worse and I needed a new TC. Everyone pointed to it being an electronic issue since the PCM was commanding it to unlock. But in the end the TC was on its way out. I think there is some weird deal that tells it to unlock and relock, or some kind of fail/safe deal. No codes, no blinking lights, and the only way I finally got BTS to send me a new TC was when I watched AE and looked specifically when it was 100% locked and there was slippage rpms. There was also oil in the main harness plug on the passenger side of the tranny that went to the valvebody's. That made me think that oil was leaking through the trans and into the plug, then the excess oil in the plug was making the TC unlock and lock. I changed those out as well when I changed the TC. I don't think that was the issue but it is something for you to look at as well. It did take months of it unlocking and relocking for it to finally start showing the increased tranny temps. It would sometimes only do it once and then not do it again. Only when you are accelerating and usually when the tranny got warmed up a little bit. Also, I was running Swamps tuning... [/QUOTE]
