The TCM on a 2001 Town & Country is usually located inside the transmission, or in some cases, it might be mounted on the transmission case itself, depending on the specific transmission type (e.g., 3-speed automatic, 4-speed automatic). You won't find it as a separate, easily accessible component like an engine computer.
To access the TCM or the solenoids within the transmission, you would need to:
1. Identify the exact transmission type in your van (often found on a sticker on the transmission itself or in your owner's manual).
2. Consult a repair manual specific to your van's year and transmission. This manual will show you the location of the TCM (if it's externally mounted) and the procedure for accessing the valve body (where the solenoids are located) to replace or inspect them. This is a more involved process usually requiring transmission removal or partial disassembly.
If you're having transmission problems, it's highly recommended to take it to a qualified transmission specialist. Working on the transmission is complex and requires special tools and expertise. Incorrectly diagnosing or repairing transmission issues can lead to further damage.
