Early TH125C transmissions used a "kick down" or detent cable to control hydraulic pressure and shifting.
The cable connects to the throttle body, and then to the transmission.
Check the cable for kinking, binding or broke. You can remove the cable from the TB, pull on it, there should be tension on the cable, if not, then the cable is broke.
Get this fixed ASAP, because it will cause an internal leak in the trans, and the trans will have to be replaced.
