727 transmission throttle control spring ?
i have an 89,2wd with a 727 automatic.my question is do i need the throttle valve return spring?( pn 53009055)that's the spring that runs from the transmission throttle control cable to the injector pump lever ball stud. i have high gas pedal effort form 1/2 to full throttle. with the spring removed the gas pedal operates with much less effort.the big question,and can't seem to find an answer from any local experts is,how will disconecting this spring effect my transmission? don't want to mess something up,because i just don't know exactly what this spring does.i looked through many threads for pictures and some have this spring and some don't.this question has plagued me for some time and i just can't find the answer.any help or thoughts appreciated.

Yes, you need that spring there. If your pedal effort is high, check the bellcrank for rust on the shaft.
Also, like Ryan said you can pull the inner throttle return spring out of the double throttle return spring. There's a torsion spring on the throttle lever so you still have a fail-safe.

It seems that there is a metal sleeve that protects the steel cable inside. Mine had come apart and was causing a bind that wouldn't allow for smooth pedal movement. Fixed it with a set of wire crimpers and some epoxy.

could be but the 3200rpm gov spring and the throttle linkage ball swap makes these things shift weird. I am still trying to fingur out a way to make it shift right.
