so, i have a 94 s13 coupe sitting in my driveway that needs an automatic tranny. i've been searching at local salvage yards and the only ones i've found have 160-200,000 miles. i know that with that type of milage, a transmission won't last very long. anyway, i just need to know if an s14 auto tranny would work because i can find those with way less miles. if not, what are the differences?
