Hey, Ive got a VK 308 with a M21 Manual currently in it, im wanting to convert it to an auto. I plan to shift kit and all the bells and whistle to the auto. Which gearbox should i go for and why? Im not sure which one to go for. Thanks, Chris

you will get a million different answer, but if ur spending good a good amount of money in the build of the auto just about any will do the job, t400 would be my personal choice,

If it's a 308 just go with a trimatic box, but if your thinking of stroking it later go for a Turbo 350, Turbo 400 is designed to run better behind Big Blocks, all you would be doing is draining the power out of your motor.

youll fit a trimatic on if you had an m21.. some mates have run them on real strong 308's without an issue, and when they copped a caining i mean a caining.. at the same time ppl call them the traumatic.. lol
