bought a 86 blazer 350 4x4 with i believe a 700r4 tranny counted gears on shifter it has 4 from drive down to one, from a guy i know because he said the tranny went out on it i changed the a/t fluid and filter and now it moves but you have to really hit the gas to get it moving seems like it is slipping to me what do you guys think. cant really complain about getting it for 400 bucks when it runs and 4wd works and all the good stuff
