2003 Dodge Grand Caravan TCM
Dedicated transmission computer for the 2003 Dodge Grand Caravan. It reads shaft speed and driver demand, then commands line pressure, shifts, and converter lockup.
On the 2003 Grand Caravan, the TCM watches input and output shaft speed and decides when to shift. When it starts to fail you get limp, a flashing OD lamp, or a start-in-second — even after a clean fluid service.
How a tired TCM acts
- harsh garage shifts that a filter and fluid did not change
- speedometer that dies and the trans then has no idea what gear to command
- no upshift, or a trans that starts in 2nd and stays there
- no-start after a jump from a portable pack
- OD light flashing with a stored solenoid or gear-ratio code
We program it to your VIN before it ships, including the immobilizer so the keys you already have are the ones the car expects. Lifetime warranty. Ground shipping is $14.95.
