One problem related to manual transmission has been reported for the 2002 Mazda B3000. The most recently reported issues are listed below.
Transmission will not shift into overdrive until speeds of 58-60 are reached - when accelerating. Took vehicle to dealer for the complaint. Dealer tech said vehicle would not shift during 'agressive accelerating' . Driver must ease up on gas pedal before transmission would shift to overdrive. Said this was normal. Never heard of an automatic transmission with such requirements. None that I have ever owned required an easing up on gas in order to shift. When I followed dealers instructions, vehicle will still not shift until it has been driven for some period of time. Under such conditions, I can't get into overdrive for the trips I take, so the overdrive does me no good. Vehicle gets very poor mileage as a relult. Don't think this is a normal condition. I only have less than 2000 miles (since oct 2002) because of such driving conditions and poor mileage.
