1st isn't that low. It's just that it needs a better synchro design to work right. It's as if they designed the gears and bearings for 90wt oil and the synchros for something a LOT thinner.
You want a low 1st gear? Hondas are known for that and they can shift into 1st gear easily at low speeds. They don't exactly have chintzy gearsets either; they're overbuilt to use the thinner oil and most can hold 400+ hp as long as the diff is replaced with a stronger limited slip unit. My Honda Fit redlined 6500 rpm at 28 mph in first, and 50 mph in 2nd, and 68 mph in 3rd... that was very low gearing, yet it shifted like a knife through hot butter every single time.
My Tacoma runs 5500 rpm doing about 39 mph in 1st. Average gearing for a stick
I also cannot get my Taco into 1st while moving unless I double clutch with a very slight rev while in neutral. Using Redline MT90 on 40,000 mile change intervals. 2nd gear almost always clunks too, but the rest are fairly smooth. It hasnt gotten any worse in the 50,000 miles ive driven the truck, and theres no metal in the trans fluid that would indicate extreme wear.
