I need some assitance in finding out why my hold light, flashies after revving my engine, The transmission has been rebuilt, I also have installed a new engine. I had this problem before I changed the transmission, so I never thaught it was the transmission I had put in afterwords, the transmission I know have in has also been rebuilt however I have the same hold light problem can anyone assit me in telling me what I can check to find a solution to this problem. I don't seem to have a problem driving, the gears seem to change out fine. however, when I do reach maybe 100 or so kilo the light starts to flash again. if I turn off the vehicle and turn it on again I am ok for a while. of course when the light starts to fleash I am stuck in a specific gear not sure which one though. I check the TPS and that seems ok. I have parts from my old transmmission if necessary so hopfully I have what is needed to repair the problem.
