i was bored and started looking up what it would run for a new tranny, for what kind and such. saw the usual upgrades tko 500 & 600, plus the t-56, are there any others out there, other than the 3550 and stock t-5. im looking for something, i want to go for the t-56 but i doubt i can gather the funds to pull off the whole project. since the t-56 is gonna run around 4, and the tko looks to be more like 2, definitly a bit saved. what do you guys have, and how have those held up with what power? what would u recommend? i hope to be getting a power adder shortly and running 350-400 hp to give a ballpark on power. thx.
