I own a GT 245 and have developed a no movement (forward or reverse) issue with the pedals. This happens when I'm on it (180 lbs) but will go forward/reverse when I'm off and then push down on the pedals. I've noticed it slightly and progressively got worse till now, and it won't go at all. The pedal does not retract on its own but seems like its broken. Following it back the arm moves in both directions back to the transmission switch. There seems like there should be more tension on the pedals. I looked for a spring regarding the tension idea but didn't see any or if one is required, it fell off. Any ideas I can try to diagnose this issue?
