Ok...

I had made a previous post about having my tranny rebuilt and then it throwing a code 16, which is Trans Temp Input. After the tranny guy replacing the sensor three times, and going through 1 re-manufactured, and 1 NOS TCM thru E-Bay, same dam code 16 with O/D light on. We're both puzzled as hell.
I even went ahead and changed the thermostat, and engine temp sensor, still same.
However, I've noticed the more I drive it, I'll go no more than say 10-20 miles, and If I hit the O/D button, boom, light turns off, and O/D works flawlessly. I only drive the dam thing to/from work, 2 mile round trip. I try to take it out as much as possible to monitor it, and I have noticed it starts working a little bit sooner each time. It's a really weird deal. But once it kicks in, I have no issues, until it sits overnight, or for long periods of time,then light goes back on, and same process.

Any thoughts on this...any one??? Please
