Greetings ! New to this site - referred from Corral for tranny advise. Here's the issue. Had a local speed shop install in a TCI R470W streetfighter unit and new lockup TC to replace my auto in my 97 mustang gt 4.6. After shipping the wrong unit, TCI finally shipped what appeared to be the correct unit. At least it bolted up. All linkage (which required opening the trans andd modifying the valve body) and sensors were swapped over, Now it's in, however, there is no 1st gear, The OD light blinks constantly and the OD button doesn't work at all. I've only driven it a short distance - but the engine cut out twice. Sooo, it's now parked. No one seems to have a clue as to what to do next. I have a very limited knowledge of these units - but I'm going to have to champion the fix since TCI has not been much of a help and the local shop has no clue - please help, any and all advice would be appreciated. Also, can anyone recommend a shop in the Tampa / St. Pete/ Clearwater area that can help me to sort this out ?
