Having trouble finding the transmission error codes for a 2002 450 STX qt. First of all who makes the 16/2 power shift transmission in these?

Codes are:

05041
56016
56043
56044
56045
56046
56047
56050
56051
56052

There may be more, this is the last 10.

This machine has a "Performance" chip and getting some engine communication codes as well. Suspicious that the chip is causing these but not sure. I don't really need the chip and was thinking of removing it.

Getting other codes related to voltage. I can find a list of codes here:
Case and New Holland Error Codes For Tractors at Valley Implement

But cant find these ones from the transmission.

Any help is appreciated.

fault codes

Have you cleared them to see if they are active or stored? That would be the first step, then see which ones come back. The attached images contain the requested codes.

Thank you so much for the codes. I have cleared them and it seems if I am patient after start up and don't touch anything for a minute or so, it doesn't give codes.

If you get a lot of codes on a STX that don't seem to be related my experience points to low voltage or terminators on that model there is one on front left of engine and behind main display panel.

Thanks for that. Can they be tested? or are they easily changed. Seem to get a lot of voltage related errors yet voltage is strong, batteries are new and cleaned the grounds.

CIH had a updated terminator, if your tractor doesn't have the updated one replace them, I believe they are in the 50 dollar area US dollars, Scott.
