30 series vs. genesis powershift

what were the differences in these transmission. other than a few buttons to make the computer do things and a small accumulator, i don't know what's differnent. any smarties know???

The difference between the F1 and F2 clutch ratios is greater in the 30 series, giving it 18 progressive speeds. While the Genesis transmission has eighteen speeds the top two speeds in F1 are roughly the same as the lower two in F2. Thus they call it a 16 speed. Shifting down out of 10th on the Genesis, 8th and 9th gear use the F2 clutch, while shifting up out of 7th they use the F1 clutch. Therefore the Genesis has two different, but roughly identical, 8th and 9th gear ratios.

The tranny in the Genesis uses helical gears as opposed to straight cut in the 30 series. This makes it quieter.

The overlap that Larry talked about makes for a much smoother 9-10 shift.

Both transmissions are built by the same company. They revised the transmission shift pattern in North America to a 16 speed, primarily due to the roughness of the range shift both going up and down, this requires a different shift body, and different computer control. Very early Genesis transmissions can do with some improvements in the range and reverse clutches, but these are already in all the later built units, primarily has to do with lubrication when roading to prevent wear and heat on the reverse clutch plates.
The few extra buttons are controlled by the newer computer, and are just a little handier for some applications. Not surprising as computer abilities increase dramatically every few years so newer ones can do more.
The control handle is a completely different design as well, and the safety start switch is incorporated in the control handle of the Genesis.
Otherwise, is pretty much identical inside, most of the gears and clutches are pretty much the same, the service tools for clutch work are the same as well. Genesis does not use a torque clutch in the flywheel, just a spring damper plate, And the oil supply was moved to the charge pump for the hydraulics from the previous internal pump.
All in all, a darn good transmission, even if it was built originally for highway truck use behind bigger engines by a JD owned company.

i was wondering how they only had 16 when my 8830 had 18. So i probably want a later model because i'm constantly on the road? what year did they change that??

I'm not absolutely certain on this question. Bern likely is. I think some European models had 18 progressive speeds all along. I don't believe the US models got them until Buhler bought them from NH , but here again, I'll defer to someone that knows for sure.

so the buhler's have 18 speeds??

not sure on this either, but thinkung at least at some point they sped them up.
