You have a H41 transmission which has a first gear of ca. 5:1. Swap in a H42 if you want a higher 1st gear.I still have this 1974 HJ 45 transmission with the bull low 1st. Anyone know this model? I tried it out and didn't like it. I t was like having a 3 speed and I took off in 2nd.

I wish I had one that low, my low in my h55 is low but not as much.. if ya run 35 or 37 inch tires, it is needed.
Thank you for this. I was not aware.. Good Info..H41 and H55F share the same first gear. Some GM four speeds like the SM420 and SM465 had a 7:1 ratio. Probably newer non Toyota have a lower first gear. H41/H55F are slightly lower than 5:1. The early Toyota four speed prior to 9/73 was 5.33:1. FJ25 had a 5.4:1 four speed. Only third and fourth gears were synchronized.
They are up to 4:1 low gears for the split transfer case. If you want lower for the street diff gear change is an option for that.
