The car would loose speed and pick back up it would start this around 20mph and up it would shift a little harder than normal out of 1st gear going into 2nd and sometimes when it shifted into 3rd the fix that carmd gave was eas to replace the Transmission speed sensor in which I did cost me a slick 60.00 and did not do anything to help car is still having same problem I ran another diagnostic and got the same codes and the same fix.
any suggestions would be greatly appreciated and just so you know I dont claim to be a mechanic just know a little to get by on.

Thanks James

There are a few things that could cause this code. Here are a few ideas.

P0715 Turbine Shaft Speed Sensor Circuit Malfunction - With Automatic Transmission

1) TSS connector is damaged (check pins for damage, and for moisture)
2) TSS signal circuit is open, shorted to ground or shorted to voltage
3) TSS has failed

I have actually had to replace the wiring from the pcm to the tss. The turbine speed sensor is located on the driver's side top of the engine area.
