yeah a modded trans is a must. I have one in mine and my girlfriends. Butter. My next one is going to be done by camatv on here. his is supposed to be one of the best stock modded trans around. Trans need to be inspected very close for a bent shaft, worn gears, bad dogs, and smooth movement on all the bearings. I beat myself up for 2 months with a trans that the shaft had a bur where the gear slid.
