in 88 maverick TD42 the synchro is grinding into third on the way up and down through the gears. Has happened significantly more noticeable since changing diff oil recently. i think it was 75/80 (the synforce that was reccommeded by there books) that i put in this time... will lighter or heavier be more likely to help my syncro's out??

cheers

Castrol VMX 80 is the oil to use in Patrol 5 speeds.

Many have had similar problems, then they replace the oil with the Castrol the grinding stops.
