I recently replaced my battery and starter and had the cables cleaned, since then it will not shift correctly, a code 1870 set, after disconnecting the ground cable overnight, the code went away but the transmission will not shift correctly. Mechanic said that a module in the ecm could have fried causing this to happen. Is this a possibility? Was running great and shifting fine prior to the repairs.

Do you
have the same problem?
