I have a 91 Honda Accord EX SW, I was having problems with the "S" (sport) light being stuck on. At first I could reset it by taking off the NEG battery cable for about 30 secs and put it back on and the car would come on fine(no sport light or tranny issues) and run great for a few days. Well that few days got shorter and shorter, and I would have to reset more often until it finally just quit reseting that way and was stuck in 2nd gear. I eventually had to buy a new TCU to fix the problem. I found out that there was some type of flaw in the initial making of some TCU's from a plant in Georgia. I will state that I am not a mechanic but only someone who has some knowledge thanks to alot of research online about this problem, and knows that you can be told by some shady mechanics that it is the transmission itself, so they can make some $$$$. I'm not saying that it might not be the tranny but I would look in to the TCU issue b4 sinking some serious $$$ in to getting a whole new tranny. Hope this helps and good luck!

Your Honda accord 1991 doesnt start when the overdrive light is flashing what should you do?
The O/D light flashing means the TCU (TRansmission control Unit) has a fault. Start by resetting everything (pull ECU fuse or disconnect battery) and then you need to retrieve the trouble codes stored in the ECU/TCU (Engine Control unit/TCU). Since normally the TCU will not give you a no-start condition, I would suspect something like the neutral-safety switch or the shift-position switch has gone bad. Try to start it in neutral...and try moving the shifter briskly through the gears. Any recent soda spills into the shifter???
How do you turn off the green s light for sport on the dash board of your 1991 Honda accord ex?
The S light indicates you are in the SPORT mode on the transmission. On the left side of the shifter stick you will find a small button that toggles SPORT on and off. If the button will not switch the light off and go back into normal mode you most likely have a defective TCU unit.
What does it mean when the d4 flashes after a drive on the highway in 92 accord?
Usually indicates that you have a TCU (transmission control unit) problem. Take the car to a transmission shop and have them run a diagnostic on the tranmission and TCU. TCU usually runs around $150 to replace but you can sometimes find them cheaper at a local junkyard.
Whereis the TCU on a 91 Honda Accord?
The TCU is located on the passenger side underneath the carpet where the floor angles upwards. Just peel back and enjoy. Once you peel back the carpet you will need to remove four 10mm nuts that hold the housing to the firewall. The TCU is the unit on the right closer to the passenger door. Once the nuts are removed, unhook the two electrical connections. If you are flexible you can reach underneath and remove three 10mm bolts that hold the unit to the housing. You can now remove the unit.
