Hi ,I would like to change the gear oil on my TX ? TXT? 200 1998 GAS GAS,checking through previous listings some people mention car transmission oil,10w30&10w40 gearbox oil,so any idea what I should use(grade and brand),and could anyone tell me is the hex socket screw just above the sight glass where you fill it from.

Yes that is the fill place. Dextron III Mercon automotive transmission fluid works very well and is not at all expensive. Use 380cc after a complete drain of the old oil.

Thanks for the info Barcota,could you just confirm that the gearbox only requires 380cc of oil because I was under the impression that it required 750cc dry or 650cc just drained,but then I know nothing.

Regards Andy.

380 don't sound enough. I've not had an edition, but that sounds more like the amount for pro. Check first - someone will come back to you here.

You are correct, it is 750cc dry or 650cc just drained.
