Any chance it could be the shift solenoid? It's just behind (when looking from front to back of vehicle) the trans output sensor that I had an issue with, and on same side. Looked at all the wiring and it's all looks good. Couldn't check for cuts from trans to TCM without removing the protective housing, but nothing looks like it got pinched or anything as the housing wasn't cracked or broken. Would the stealership be able to plug this into a computer and tell me EXACTLY what the issue is so I can fix it myself?
