I have done searches on manual transmission oil, I gather that Dexron II was specified for the manual trannies but all I can get is Dexron III. Even though Dexron III claims to be backwardly compatible with Dexton II, I have read that it might be trouble for synchros becuase its synth.

The question is, has anyone here used Dexron III in their manual tranny, and if so, do they like it?

My tranny has put with a lot of torque over the years and is a little baulky. The synchros are probably a little tired so I want a decent (at least proper) oil in there.

Cheers
