m/t fluid for the toyota corolla xe 1999 model with the 1.3 carb engine...

can't seem to find the recommended fluid type sa manual... unlike honda na naka specify yung spec (10w-30 engine oil).

should i just let the petron guys fill it with whatever gear oil they have or is there a recommended fluid for this thing? clutch is fine and still malambot, but in the morning i'm having trouble shoving it in reverse or 1st gear. i'm guessing tuyo na yung fluid reservoir nya sa transmission (this car receives next to no maintenance apart from oil changes once a year... at daily beater pa. i love toyota cars... massively reliable).
