TorqueFlite 727 Burned Front Clutches
Sadly my information source passed away a couple years ago. I do recall that he did say that the fronts are the ones that get burned. I don’t remember what he said about why the rears don’t.
If the fluid circuit feeds the rear clutch first then it would be more likely that pressure drop would cause front to slip while rear remains engaged. I don’t have my service manual in front of me to verify the circuit.
But I can be very confident that a kickdown issue always burns the fronts.
I replaced clutches and the same issue returned. What I found was that the pressure loss allowed the governed to remain in one place where it got stuck.
