QuestionTranny locked in limp mode. No "service engine light" on. My
tranny expert borrowed a scanner and it said bad ground.
Checked all grounds, even hooked cables directly from battery
negative. Took the pan off, retorqued al solonoides to be sure
they were grounded. Three ohmed out a 25, one at 15 and the
one in the front at 3.5. Tranny expert said his scanner read the
same and all solonoides should be OK. All connections were
cleaned. No junk in pan, forward and reverse are solid. I am
sure it is an electrical problem, but am stumped.
Can you tell me where to look next?
AnswerSteve,
Disconnect the computer and check the pins for corrosion. If this is not the case you either have a bad computer, or a bad wire to the solonoids. Remember that the computer grounds the circuits to activate them. Lastly, check all associated relays that activate the solonoids.
