The first generation Ford Explorers were available either with a four speed automatic transmission or a five speed manual transmission. The manual transmission option was the M50D-R1, and the automatic was the A4LD.

No. The transmission on the 91-94 Explorer is well known as the weak spot for the truck. Failure is so common that you can find the transmissions on eBay. My '92 is on the third transmission. The second one, direct from a Ford dealer and over $2400, lasted less than a year.
