New to the group and needing some help. Have already replaced the ECM on my car about two weeks ago since it would not go into overdrive. (NPC computers in Houston, TX). Now today the check engine light came on and the O/D light is flashing on and off. Also when in drive it has little take off power unless I drop it into Manual low. Had AutoZone run a check on it and they believe it is the shift solenoid. Need to know if this sounds right and if so where is it. Also how do I change it if this is the problem.
Thanks,
Thomas
