I'll limit myself, for the moment, to OP's enquiry. The recommended transmission fluid is Matik D (because it's 4speed). Dexron III is also compatible. Matic J is for RWD vehicles with 5speed transmission. Yes, 5W-30 is preferred (not solely recommended), but there is nothing wrong with our 20w-50 because of our warmer conditions.

Thanks for the correction sir, God bless you.

@ decotech and costee, thank you very much. I appreciate, with these am now confident to throttle it without any fear of oil damaging anything.
