At the throttle body there are 2 cables, one for the accelerator and the other leading to the transmission, just below the lower radiator hose.
This is known as the throttle pressure cable and it controls the transmission line pressure.
The throttle lever at transmission side should start opening as soon as the throttle starts to open. If the cable is adjusted too short, there would be excessive line pressure resulting in harsh shifting.
If the cable is too long, pressure would be low resulting is slipping or flaring at moment of upshift and downshift would be delayed with lack of accelerating power.
At the throttle side, note if there is any slack in the trans throttle cable. If none, release the lock nut at transmission end and adjust until there is only minimal slack. Slowly turn the throttle opener and note the movement of the trans throttle cable.
Trans lever should start moving nly when the throttle plate starts opening, not before or after. Some testing and readjustment might be required to get the correct setting.
