there is a cable assembly that runs from transmission to throttle plate {gas pedal} on engine,,,this "sets" line control pressure in transmission...this needs to be set so cable "pulls harder",or longer...pressure as described is too low which causes soft,,,sleezy shifts...cable housing will need to be pushed tward firewall about 1/8 inch to 1/4 inch,,,should be a button on cable where it is held on engine,,,which will allow cable hsg to slide back and forth,,,adj is not real fussy,,,kinda note where it is before you move it.....stronger and slightly later shifts is more desireable.....check ball assy in oil cooler line should also be removed,,,will stop OD failures....gbaum
