i bought a 2000 lincoln ls with 104000 miles on it. i bought it for 400$. when i bought it the brakes were original xD the rear tires were like slicks they were so bald, the engine idled funky (dieing at stop lights) and the transmission shifts rough when shifting from park to drive or reverse and in 2 and 3 gear. i guy had it sitting for a year. brought it up to hepps auto in isanti mn and he replaced the missfire after2 trips. now idk if i should just buy a used tranny and install it myself and see if that works, or go to the shop again and get literally raped to repair the one thats in it. i know it might not be the tranny but what would your opinions be? thanks for the help!:shifty:
