What would happen if someone used Dexron III in a transmission that required Mercon V?
Would the driver notice any difference while driving? Would the transmission simply have a slightly reduced lifespan (20% or less reduction in lifespan), or would the transmission die within 20,000 miles?
For arguments sake, lets say the transmission is a 2004 Ford Focus with about 50,000 miles on it at the time the Dexron III is added to the transmission (a full flush and refill).
