92 Accord - Gear Lights on Dashboard
92 Accord - Gear Lights on Dashboard
The following ONLY occurs during wet weather:
I have a 92 Honda Accord LX with automatic transmission. Starting
from a stop, the car feels as though it's trying to start in third
gear. Once we get going, I cannot seem to get it to go beyond third
gear. On the highway, I can't go past 50 mph, and the tachometer
stays around 3. I noticed that with the engine running and while at a
stop, if I shift into other gears, the D4 light on the dashboard
remains lit (i.e., if I shift to reverse, the R light and D4 light are
lit). The car moves in the correct direction while in the other
gears, but the D4 light stays on.
I think the Transmission Control Module (TCM) is bad, but I wanted to
get others' opinions. Is there a way I can test if the TCM is bad?
Do you have any other ideas of the problem?

Try this answer I posted before, and check the ground wires to the TCM
and check the harness that goes to the switch I mentioned to see if it's
corroded or rubbed through. You still haven't provided any history or
the mileage, but it is Wednesday :
> Problem is electrical, specifically the input signals to the computer. It should be expected to slip when the light is extinguished, since the computer has no idea what gear it's supposed to be in. The gear position sender is on the side of the tranny and is probably worn out or out of alignment, possibly because your shifter cable needs the length adjusted. Please mention the mileage and service history, like what kind of fluid you put in it when you last did a drain-n-fill. There's several TSB's that include the cable length adjustment here:
