NO.....Gears transfer all the power at a tangent to the tooth contact, SO, helical gears also force the shafts forward and backward. This force has to be taken up by the bearings. This causes more heat/friction in the bearings. Straight cut gears will cause less friction on the bearings because there only radial (spinning) forces rather than axial (forward/backwards) forces as well as axial forces. The reason Mitsubishi "thickened" the bottom plate was the original metal plate was being damaged because of people using it as a jacking point . The thick plate DOES provide a bit more rigidity to the box, but the flex in the shafts is what causes the teeth to fail. Third gear is the major culprit because there is a larger step between 2nd and 3rd gear. The reason the Toyota W5x gearboxes are stronger, is because there is a steel plate in the middle of the gearbox which reduces the shaft flex. Google is your friend. Use it... Cheers.
