2004 chevy trailblazer_lt
i found two servo upgrades 2nd and 4th gear what the difference between the two and can/could these be used together. need a lil help before i buy either one!!!!
That combo in my Trailblazer shifts smooth and quick at part throttle. But at WOT it hits hard and will squeak the belt. I just put in the regular aluminum accumulators, not the pinless ones.so if we are just lookin to firm up shifting not neck snappin (due to the 8 month old in the back seat) would the 1-2 servo, and a .490 boost be enought?
