Ford Transmission Help (Sorry My Truck Is Not A Mopar At This Time...)
At some point Ford changed a bronze bushing at the throttle pressure to bell crank connection to a plastic bushing. That plastic would break, fall out, and ruin a trans in short term. The HELP line at part stores have a new plastic bushing but in most cases by the time one knows its needed, the damage is done.
Bronze is available and will fit.
It should be a required part of trans overhaul in those year models where it applies.
