Warranty problem
1992 Honda Accord 4 cyl Front Wheel Drive 157,00 miles
----------------------------------------------------------------
I just bought a honda accord lx and the transmision is not shifting correctly (98% of the time) There are several different things it has been doing (all of them involve the d4 light) Most of the time the d4 light stays on -no matter what gear your in-I have had it 2or3 times start blinking while I am driving it and then it acts like it wants to die-or sometimes this has happened also the d4 light goes completly off while I am driving it and so none of the gears are lit up! I tok it to brake check and they did a free diagnostics on it and told me the code it was giving their computer was that the selenoids were possibly dirty or bad altogether? I ahve done some research and nothing I have read has mentioned anything about the selenoids being related to this problem (most everything says that I most likely have a bad computer for the transmission?

In electronic controlled transmission these sensors coolant temperature sensor,throttle position sensor and vehicle speed sensors are use to send signals to the transmission control module to provide upshifts/downshifts/overdrive and lock up-without these proper signals to the TCM it will not command the solenoid/s accordingly as programmed. Get these sensors check out for proper operation.
