Frequently Asked Questions
What does a T42 Transmission Control Module do?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses this information to control shift solenoids, regulate hydraulic pressure, and engage the torque converter clutch for optimal performance and fuel efficiency.
Is this module truly ‘plug and play’?
Yes. Because we program the module to your specific Vehicle Identification Number (VIN) before it ships, it will communicate seamlessly with your vehicle’s other computers right out of the box. No further programming or trips to a dealership are required.
How do I know if my TCM is the problem?
Common signs include a lit Check Engine Light with transmission-related codes (like P0700), the vehicle being stuck in one gear (limp mode), harsh or erratic shifting, or a complete failure to shift. A professional diagnosis is always recommended, but these are strong indicators of a failing TCM.
Where is the TCM located on my vehicle?
The location varies by model. Common locations include the engine compartment on the driver’s or passenger’s side, near the strut tower, next to the battery, or under the air cleaner box. The installation is typically straightforward and can be completed in under 30 minutes.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module at your convenience, simplifying the repair process for you.
