Mazda BT-50 Gearbox & Transmission Problems

It is a relatively common complaint with the BT-50 when towing and we get quite a lot of complaints from Navara owners as well. The answer seems to be that the clutches fitted at the factory are marginal for heavy-duty use, and the answer from mechanics we've spoken to is to fit heavy-duty aftermarket clutches.

Jumping out of fifth gear is a common problem on early BT50s, but a fix was supposed to have been introduced in late 2007. I agree that Mazda should bear at least some of the cost of the repairs so take it to a Mazda dealer and submit a claim.
