I am leaning towards either TCI or Hughes, mainly because they are well established companies with good reputations. I have ridden in cars with TCI streetfighter transmissions, and was impressed. I haven't had any personal experience with Hughes, but I've heard good things. The Hughes 4L80E is a few hundred $$$ more than the TCI, which isn't a big deal to me. I just need something that is going to take some abuse. Anyone out there have experience with either transmission, good or bad?
