Sorry to reply to ancient history. On turbo cars the transmission
dipstick is positioned so that one must move the transmission throttle
cable aside to pull it out or refill the box after a trans oil change.
Most times the cable sleeve has backed out of the ferrule. If you are
careful you can grip the sleeve with a couple pairs of visegrips and tap
the sleeve back into the ferrule. If you collapse the ferrule the cable
will jam and defeat the repair. Once the sleeve is back in place, snap
the cable like you playing a guitar and adjust it so that you can hear a
decisive click in the gearbox when you release it. Take care that the
cable is properly aligned on the throttle spool when you are done.
The transmisson throttle cable (kickdown cable) turns a cam that
increases throttle pressure in the transmission. When throttle pressure
exceeds the governor pressure the transmission shifts down. When
governor pressure exceeds throttle pressure the transmission shifts up.
If the cable is at fault usually the 1-2 shift will be much later than
normal. With light throttle the transmission should shift into third
gear by 25 mph, the third gear-over drive shift should occur between 35
and 40 mph.
The goal when driving is to miss the maximum number of objects.
