Is the TPS a Cummins part? Is the speed sensor a cummins part?

 

Does anybody have a picture of this? Also do they replace this when they rebuild the transmission?

 

Most good shops will only replace the tps if it's not working correctly, it's rarely replaced routinely. They will usually connect a lap top computer to the diagnostic port under the dash and take it for a drive, a malfunctioning tps is very obvious.

 

What year cummins do you have Gabbyfan?
