Hey guys need some serious help. Had my transmission rebuilt 12month ago and now its not running right. It will go into gears fine but will not exceed 20mph. Past that and it seems to go into neutral. Any help is appreciated

Is it shifting or staying in first gear? Has the check engine light come on?

If the engine revs normally in neutral or park and you found that code, check the wiring harness to the pcm to make sure it is tight and not corroded. If it is good, just for the heck of it, check the catalytic converter to see if it is plugged (red hot) and the fuel pressure.

If you need directions, let me know. Also, if you deleted that code, let me know if it has come back.

Hey joe ok so I reran the code and its given me P1716 no communications with pcm. Where is the pcm located and how do I know if the harness is bad or its got a bad ground, etc.

It shift and go into gears fine its not going beyond 20mph. No check engine light either I ran the scanner tool and first it says communication with pcm and battery disconnected. Now its not reversing when in reverse gear.[/Quote:c312308e4f]

The PCM is located in the left front of the engine compartment. Check the pins for corrosion and evidence of any of them being pushed too far into the connector.
