how many miles are on it
while i look into the trans what all have you done to try and fix the misfireis your speedomiter working
your pcm might be bad (the computer) did all this happen at the same time if you have all thoses codes on the transmisiion you got more than one sensor tripping heres a list of possibilitys for the missfire
and the only thing that links the two together is the computer try taking one from aneather car and just testing it and see what happens but thats what its sounding like
im sure you know whatthe codes mean but if you need i can tell you what they all are
yes, if its bad it will give you the codes.
when they go bad they send false signals to the the parts of the car that controll how it runs causing it to act up and giving other codes
not sure but theres only a few places they put them one is behind the dash in the center near the floor aneather is behind the kick panel on the passenger side or under the dash drivers side i can find out tomarrow and let you know for sure its normally silver box about 8in by 8in and about 1-2 in thick
