I have a 96 navara 4x4 dualcab with a blown gearbox. The car was origionally a 2.7l diesel but the motor was replaced with a 98 model qd32 and fitted with a dts aftermarket turbo, this was done before i bought it. I have found a reciept for the gearbox being reconditioned 10,000km before i bought it and i only got another 10,000km then had to get it rebuilt myself. after this i got a further 50,000km and it has blown again. I am wondering if this would be caused by the motor being mismatched to the gearbox. also if a box matching my motor will fit in my car. any help would be grately appreciated thanks.
