new to the forums. i usually would be able to identify a problem... but trannys arent my thing.. my 89 ram is ''thumping'' hard.. pretty much always when i take a turn and sometimes on a straightaway. in the cab it feels like its under me. maybe a problem with the yoke or something in the bellhousing? it seems to be shifting into gears fine though.. so i dont know.. any help / advise would be awesome.. oh and its a automatic..
