Just as ECM (Engine Control Module) can also mean Electronic Control Module. How about "trans computer?"

I found this on another website. anyone know what this means? cuz my transmission has this same symptom? TCM USES ACCELERATOR PEDAL SWITCH TO KEEP TRANS IN 2ND GEAR WHEN COMING TO A STOP. THIS IS DONE TO REDUCE SHIFT SHOCK SWITCH IS "ON' AT IDLE WHEN THROTTLE IS CLOSED. BE SURE THERE IS 2 TO 3 mm OF SLACK IN THE CABLE. PRESS Y FOR ACCELERATOR SWITCH TEST --- More--- ---3--- A simple cable adjustment may be all that is needed to repair the problem. Plus, Troubleshooter lets you perform a switch test just by pushing a button. Overhaul Tips displays procedures and specifications, and includes transmission specific information from TSBs, working technicians, and service organizations like ATRA (Automatic Transmission Rebuilders Association) and the ATSG (Automatic Transmission Service Group). |

This sounds to me like you just have to adjust your throttle cable. Just tighten your throttle cable up and that should take care of it. At least that's what I got out of it. As far as the measurement, I don't know if that is a direct measurement or a deflection measurement. |

Well actually with most cars as far as I know TCM stands for...we dont have one on these cars so..... Transmission Control Module - TCM. Controls the functions within automatic transmissions through various electrical and mechanical inputs. Same function as the ECU has with the engine. ...as found in our wonderful glossery of terms in the General Tech section. Most traction control units are very manufacturer specific and have their own funky names. Mitsubishi's is: M-ASTC - Mitsubishi Active Skid and Traction Control. |

I'll second this one, too. BMW has ASC+T (Anti-Skid Control w/ Traction), DSC (Dynamic Stability Contol) and then a variant of that, Dynamic Traction Control or DTC.Then Benzos and their DCX brethren have ESP (Electronic Stability Program), Lexus and Toyota has VSC (Vehicle Stability Control), Porsche has their own acronym which is escaping me, etc. and so on. |
