So I was reading on the performabuilt site about how 4th gear goes out and causes all kinds of thinks like rock hard low rpm shifts... well... I thought my rear end was going out but if I keep my car in 3rd gear it seems like all my problems go away.

Im really thinking my rear end problem could be a tranny problem instead. Ive tried my best to get something to break but it doesnt.. ive been all over the car... Still cant find the issue..


I KNOW for a fact the first time I changed tranny fluid it was thick and black...

my rear end appeared good to go...

where to blow money first???
