2011 tpms on a 2010
 

Anyone know if a 2011 tpms will work on a 2010 t&c
They're both 433mhz but have diff numbers

They should both be compatible with eachother.

In the U.S. both the 2010 and 2011 model year T&C TPM systems operate on a 433 MHz radio frequency and a 433 MHz TPM sensor.

Although 315 MHz and 433 MHz sensors are identical in size and shape, they are not interchangeable. Always make sure the correct sensor is being used. A RKE-TPM Analyzer can be used to determine the sensor’s frequency without having to dismount the tire.

The TPM sensors are designed for original style factory wheels. It is not recommended to install a tire pressure sensor in an aftermarket wheel (This could cause sealing and system performance issues). Do not attempt to install a tire pressure sensor in an aftermarket wheel. If aftermarket wheels are installed and do not contain tire pressure sensors, the system will not function properly and the driver will be continuously notified of a system malfunction.
