rough shifting isuzu mu-x m/t 2017

[waldnerdoe]

i replaced the transmission oil of my isuzu mu-x m/t 2017 model with a 15w-40 engine oil and the result was that the shifting from 1st to 2nd gear and from 3rd to 2nd gear became rough. also a noise occurred during morning start-up is observed. the recommended transmission oil for this vehicle per manual is besco transaxle 5w-30. you may also use 5w-30, 10w-30 or 15w-40 engine oil per isuzu mechanic instruction.

did you experience this?

I'd follow the oil grade.

15W40 is for Crosswind MSG5K trans, while axle oil is 85W140

i am curious.
why not stick to the recommended oil grade?

[waldnerdoe]

just curious also using thicker engine oil

Hindi ba, usually kapag manual transmission gear oil GL-4, nasa SAE 80, SAE 75W-90, SAE 80W-90, SAE 90?
Ung GL-5 ng Isuzu, 85W-140.
Parang malayo ung 15W-40.

are you really looking at the correct box bro?
bakit engine oil ang gamit sa transmission? usually mas mataas ang viscosity grade ng transmission oil.

[12vdc]

Same grade yung engine oil sa gear oil sa Isuzu. Transfer, rear, front axle ang nagkaiba.

[Mask Rider Blac]

Oo nga, thanks.
Ang baba pala ng viscosity ng oil for Isuzu manual transmission.
Dko pa nabasa ung part na yan sa owners manual, ang kapal kasi. D-Max ang sa amin pero pareho lang yta sa muX.

For 1st gen isuzu mux, pwede engine oil ang ilagay sa m/t ransmission. Ang Sae 90 gear oil ay sobrang lapot compared to 15w-40 oil
