I've got a '94 Corolla with an automatic transmission. An engine swap (from a 1.6L to another one) was recently performed on it because the previous owner blew the original engine. The problem now is that it accelerates the same way my stick '93 did when the clutch was burnt out. Stepping on the gas hard revs the engine instead of accelerating and causes a burning smell. I know there is no clutch in an auto tranny, so what would cause the same effects as a burnt out one?
