I have a 2004 f-150 FX4 New Body Style and the overdrive recently went out I have a programmer for the truck and it is pulling the code 4 gear ratio error.

Also when it is raining when the truck hits 40 to 41 MPH it sets off the ABS light, the throttle body light (wrench) in the dash and then the check engine light I plugged the programmer in again and it said throttle body control actuator system - forced limited power code # P2106

Please if anyone is having, or has had this problem let me know I cannot think of any more solutions w/out spending alot of money
