I have a 2004 jd750c lgp and it is mistracking to the right and gives me a F636 code. As anyone had this code before? The little I read it involves the speed sensors. Any suggestions on what this all entails To fix or how to fix?

I also have the same machine and had the very same issue- Deere dealer came and put in and Calibrated a new speed sensor and fixed it 100% at a total cost of $1000.00

Welcome to HEF Dan;)! Please post a serial number. F636 is for the left track motor speed sensor or it's wiring/connectors. In reference to what JB said those particular series machines did have speed sensor issues.
