I had these codes on my 2010 2.3L Duratec 2WD 2 Door with automatic transmission. I have a C1222 ABS code (Speed Wheel Mismatch), a C1296 (left front wheel speed sensor input signal fault) & a C1297 (right front wheel speed sensor input signal fault). I also have a P0733, P0734 & P0735 transmission code and the transmission is not shifting correctly. I was thinking the ABS faults might be the cause for the transmission shifting issue.

My wheels are factory correct and all four tires are correct size 225/70/15 as per the door card so I don't have any idea why the C1222 code is popping. I replaced both the front left and right wheel speed sensors and reset all codes...went for a test drive and all three codes came back almost immediately. Also transmission is still not shifting correctly so I didn't solve anything. Does anyone have any ideas on what I can do next to figure this out.

Thanks!
