The Mitsubishi R4A51 transmission is a fully computer controlled rear-drive transmission with a lock up torque converter. The R4A51 was only used in two wheel drive models. The V4A51 was only used in the Sport four-wheel-drive models. This particular Mitsubishi transmission was installed in said vehicles from 1999 to 2003 only, including the Mitsubishi Montero and Montero Sport SUVs which used the 3.0- or 3.5-liter SOHC [single overhead camshaft] engines. One of the most popular and cost effective replacement transmissions is a Mitsubishi Montero Sport used transmission, referred to as JDM.
JDM is an uncommon subject to most transmission buyers. However, JDM is also one of the most viable and cost effective replacement transmissions for those uninterested in a remanufactured transmission. JDM is an acronym for Japanese Domestic Market. Briefly, these are transmissions removed from cars in Japan that get turned in because the engine does not meet the ultra strict emission requirements.
Instead of fixing the cars engine [in Japan], it is more cost effective to buy a new car, in Japan. With this in mind, and the fact that the transmissions have less than 40,000 miles on them, shipping them to the United States and making sure they are examined and certified good to be sold, is how Japan disposes of them and makes a few bucks.
In America a car with 30 or 40 thousand miles on it is brand new [almost]. For what seems like a mere pittance compared to other replacement transmission options, one can buy a JDM used transmission and satisfy a serious dilemma with a very viable solution. I would definitely consider a JDM replacement transmission if I had a car with a Japanese transmission.
Of course we can locate and send a used transmission taken out of a car in America.
