The T50 did have a numerically high first gear.
I forgot the ratio in first, I am thinking it was 3.20-3.50 range? Would have to look it up to be sure. It was low for sure.
I have 4.10 gears in the rear axle & w/the T50 trans I could only make it half way through a short intersection (RPM @ 6000) & had to shift into second gear.
