voltage/ tranny problem... related???
so sunday i put a new alt. in the jeep and monday my voltage spiked to 19 and tranny wouldnt downshift to 1s gear at a stop i had to manually shift it to first, had the alt tested it tested fine and like new from factory...
is my ECM bad? (i have a voltage regulator in the ecm) and would the voltage spike cause my tranny to screw up?
