Ah oh, looks like trouble! Correct me if I'm wrong, but it sounds like I
wont be able to get wide open throttle if the cable is adjusted properly. Or
will the cable move a little more under the right condition. This engine and
tranny came married together from the factory, so I know they are matched.
It's an '89 GM TPI all original. The previous owner tried it in a '91 TBI
truck. He described it as 'U-joint breaking shifts when pulling a large load
at low speeds'

thanks for the info,
