2014 Mazda 3: Anyone switched Ford XT-M5-QS Full Synthetic Manual Trans Fluid ?

[waid302]

After 20,000 miles, mile 6 speed manual still has little bit of grind going to 2nd gear and going to 5th gear even after adjusting as shown on TSB.

It seems that the Ford XT-M5-QS Full Synthetic Manual Transmission Fluid cures all grinding with Mazda's Manual Transmission espcially in Miata.

Amazon has it for $26 / Quart: https://www.amazon.com/dp/ (commissions earned)


Just curious, is anyone using Ford XT-M5-QS Full Synthetic Manual Transmission Fluid in their 2014?

Has it made it smoother shifting?

How many quarts do I need. 2 or 3 ?

Thanks
