[jelani6428]

Ok..so ive searched and havent found much close to what im experiencing. My SVS anti lock and trac off ligts are on. When im on the highway or just at high speeds.. right around 60-70 mph ..the car would stay in the same gear but the rpm is going up while im losing speed..I wanna say that its the speed sensor but when i took it to Aamco(which i shouldnt have) they told me the transmission is goiing bad.i wanna believe them but at the same time im seeing alot of people with almost the same pronblem saying its the speed sensor. Any help would be appreciated. A little facts..I replaced the two front hubs last year june..i have 140000 miles on the car.
