some peoples t5's live forever with constant abuse and others just fall apart, its confusing, i know at least one 350-375hp paxton sc 5.0 that constantly bangs gears with dr's and it doesnt break, and its the original 128k trans. but then my buddy with 140k pretty much stock is on his third trans in 50k of pretty much the same abuse. maybe its the gearing, the sc 5.0 has 3.90 and the stockish one has 3.08s
thats one advantage the t10-m20-22 trans has over the t5, overdrive is great-but i only broke my first m21 that had lived its first life in a 396 chevelle that got beat the f up after god knows how many clutch dumps, clutchless shifts, wot shifts, speed shifts and similar doggin over a six month period where i made a vow to burn rubber first thing when the car warmed up, the second trans, a wide ratio m21 with that super long first gear, i did stop burning rubber for breakfast, but by the time i put that trans in, i upgraded to a four puck clutch and heim joint shift linkage, i street raced the four speed setups more than 50 times each, and went took 15 hard runs at the track with some resemblance of hook for the last five runs- and it never even sprang a leak. if iwere doing another v8z and going stick and didnt have t56 money, i would go four speed in a minute or less, my favorite tranny, cause it likes the pain, and brings the pain! and their light too! thats just me, and i know im weird.
