Okay so here's my issue; just bought this 93 LX Foxbody with a 2.3l 4 banger and I think it has a A4LD 4 speed automatic. The car starts great, but it idles so crappy. Is like a chug almost. There's a high pitch squeal when it's been sitting for 30 sec. and then I drive it. My tranny also has gone out, last night got stuck in some snow and gunned it till I got out but then I smelt a burning oil smell. I parked at my friends and looked under it, oil was dripping at a decent speed. It's winter and the snow is usually under all my vehicles, but the under side was bare. Just looked damo, I need help asap! Also, will a C6 transmission fit in my car?
