Alright, so I'm not down here in CS for more than a day and the transmission on my sub is acting weird. When you put it in drive it clunks hard, not the normal clunk it makes because its got 220k miles, but it shakes the truck. Also it revs up real high for the shift from 1 to 2, and it is violent too. I checked the fluid, its fine. Its a 2wd half ton with a 350 and I guess a th350. I don't really know. I know its got alot of miles, don't tell me I need to rebuilt the trans. Tell me what the problem could be.
