Hi .

Normally having these two codes point towards a Bad TCM ,if the wiring and connections are good .

All i can suggest with this is to remove the connections on the TCM and check all are good .

wiring you said you checked ,so points towards the TCM which is just above your right knee up under the dash .

Still need additional information then please get back to me with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.

Your deposit does not pay me until the answer is rated in a positive way,
A bad rating does not constitute a refund.

If you are not happy or you have sorted out your problem before the answer then please let me know with the reply button .

Kind regards Greg.
