Well hopefully someone has the knowledge to figure this out......

I was trouble shooting and pulled the tcc connector and cleaned it with twister and reset the ecm, the transmission shifted fine for a coulbe of hours then after sitting for about 3 it started up again some i believe its the computer because now it shifts fine when it wants to.

Hmm try the ECU, there pretty cheap, If u suspect the connector, try tweaking the pins in the connector on the trans harness alittle bit and it will force them to mate in the connector firmly
