How much would someone pay for a used PTU. I had it replaced by the dealer when it started to leak due to a gasket failure. I just didn't trust them to change out the gasket. I sold my SHO so I no longer need to hang onto it.
Personally, for one in excellent shape, with no issues, I would only pay a max of 50% cost of new. Given the gasket issue, max I would pay is something to the effect of 30-35% max.
The fluid IMHO, or rather the insufficient qty of it. The PTU has gone through several iterations without resolving the issue. Regular fluid changes + the extended vent ar a minimum are needed. The gears get chewed up once the fluid breaks down
