First thing is to check to make sure you have the correct lube in your transmission. I had a quick lube put the wrong type of lube in my transmission and it created a problem that made it seem my transmission control was going out. Your Honda dealer should be able to provide you with the correct Transmission Fluid. Also a quick check of your tranny is while you are driving down the road push your gas pedal all the way to the floor. The car should downshift soon after doing this and accellerate. This quick check is accually mentioned in my car's owners manual.
I just bought a 91 Q45 and the tranny don't work, there is no garbage in the fluid and someone said it might be the module. Can you tell me where it is located. Thanks
The transmission control module is located on the drivers side just behind the headlight. you can tell it has a large wire harness there.
The PCM is short for powertrain control module. It monitors the engine and transmission and makes everything work together. For example, the PCM will check the vehicle speed, RPM, throttle position and tell the transmission when to do a 2-3 upshift or downshift when necessary. It also logs trouble codes if there's a problem.
Many things are inputed to tell the tranny to shift. The Solonoid pack executes the shift, and the transmission control module tells it when to shift. A good resouce is www.allpar.com.

My 1997 hombre will not start. How can I tell if it is the relay switches or the control module.
How about checking engine control module? Would that tell anything?
You can tell when your car will take too long to shift to a higher gear when accelerating. Your transmission can also jump out of gear as well.
Call the honda dealership, give them your Vehicle Identification Number (located on the frame), and they can tell you exactly what it is.
My knee-jerk answer would be a TCM (Transmission Control Module) problem, but have a shop hook up a scan tool and they can tell you what is wrong.
To determine if your 1987 Chevy van's cruise control module is bad, check for common symptoms such as the cruise control not engaging, disengaging unexpectedly, or not maintaining speed. You can also inspect the module for physical damage or corroded connections. Testing the module with a multimeter for proper voltage and continuity can further confirm its functionality. If necessary, consult a professional mechanic for a thorough diagnosis.
