check engine light on. car will not shift out of second gear. car stalls on heavy acceleration,restarts quickly. DTC's P0102,replaced MAF sensor,code reoccurs.
P0753,P0758,P1645,P1860 are the remaining codes. Anything come to mind?

Thanks for the reply. I have been told that a tranny flush with filter change may help. I have also been told that because of the variety of codes that the ECM may have to be replaced.

one thing I forgot have your battery checked for condition including load test. a bad or poor battery will send multiple codes an dno the ecm isn't normally a fault,
