It does have the 47RH/618 but so few people know what they are. I have not torn it down but it should have the additional disc and 5 gear planetary on the OD section.
Redline is 2400 rpm. Stall is around 2000 rpm and torque peak is 1900.

The $300 kit sounds nice but I can't afford that and probably won't be able to for some time.

I'm seriously considering pulling the OD section off and going through it for now. I know that's only doing half the job and will likely cost me more in the long run.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
