I think the only one I haven’t driven is a 6 speed standard shift but its just one more gear.
I had an F150 with 3 on the tree, a Saab with 4 on the tree, a half dozen 3 and 4 speeds on the floor, my last F150 had a 5 speed on the floor.
Drove a 6-speed manual in the UK recently.
Right-side driving was not too difficult to get used to, and the manual gear and clutch were themselves easy to use - even with my left hand.
But the 6 gear selector was tricky because I every-so-often down-shifted to 3rd instead of 1st, or upshifted to 1 or 5 rather than 3, or down to 2nd rather 4th from 5th.
I would have been better with a 4-gear selector if I was going to be usign my left hand to shift.
I’ve had all of them too. N pattern on the SAAB, that’ll confuse most. My personal plow truck, is a 4 speed with reverse in the lower right, the municipal plow truck I use is a 6 speed with reverse in the upper left, the interiors are almost identical, I forever getting them mixed up.
My Freightliner has a 15 speed non syncro roadranger with 2 air shifters over a 5 speed pattern, my Mack has a 9 speed over a 5 speed pattern with 1 air shifter, git ya some of that.
How about a Blue Bird bus with a 4 speed with a high/low trans. Really makes it an 8 speed. Between gears, you push or pull a red button on the gear shift shaft t change from low to high.
It’s not a sharp learning curve.
I’ve also got a few thousand mile sin 4-speed coaches. They don’t have tachometers. Instead, there is a brief shift window at certain speeds. If you miss the window, you can’t shift the gears, especially between first and second.
First time I’d had to touch the clutch on my 1986 Nissan Hardbody was today and only because a hydraulic damper seal failed. Clutch itself is fine. Back in business now. This will be the girl’s rig next year.
Had a 7 Speed Stick in my 2014 Corvette Stingray. I think I used 7th Gear a dozen times in the Year I owned it.
It’s a long way from my first Stick Shift, a 50 Ford Pickup.
