I'm looking at a 2000 ram quad cab with a short box & I got under the truck to check the block number... On the side of the engine it had a 55 on it. . My question is is a 55 Block a good number to have or is it prone to problems like the 53. . I posted this under here because the guy needs to know ASAP if im still intrested in the truck. . Also when I test drove the truck, it wouldn't shift out of 2nd gear, and when I got back they put it on the computer & said the solinoids in the transmission went bad. . Could this cause it not to shift. . The only time I could get it to shift was when I mess around w/ the throttle a little bit... Then once it shifted it shifted great through the rest of the gears...
