I have a SC300 92 that I bought from an individual. The OD light is blinking. The owners manual says tranny problems. I have no power upon acceleration. Feels like something is holding it back. I disengaged the trac on/off to see if that could be the problem. Didn't help the problem to much. Sometimes, it will take off with all the power it should have, but then when coming to a traffic light, it will repeat the process again. No POWER!
