Re: C4 Pump and Input Shaft
Ya, best to replace those pump gears.
Converter hub looks "ok".
The slight scoring where it engages the gear is normal for a high mileage unit.
Do you have caliper or micrometer to check for out-of-round?
FWIW, I have never regretted installing a new or rebuilt torque.
I have regretted installing a "supposedly good" unit.
Also FWIW, I have run gears and a torque that looked like that... on something I didn't care too much about...
It worked fine, then I sold the car.
