>>1678399>>1678411>>1678654its a truck tranny, truck engines only have a viable band of revs where they can put out useful power and not stall like 300 wide
a normal car goes from like 4k to like 6-8k, in a truck you have like 5300 to 5600. generally you have a set of between 6 and 8 gears, and a high and low range, like on a modern bicycle that has a front gear cassette and a rear gear cassette (though theyre not used in the same way as on a bike)
