mga sir gaano ba kadalas maglagay o magpalit ng transmission oil for manual 95 toyota corolla xl,second hand ko na kc nabili ,1 yr na sa akin pero dp ko lagay na trnsmisssion oil.any sign na mararamdaman bago maglagay ng oil?
On the manual, tranny oil (along with other fluids except the oil) is changed every 40,000km but given our poor driving conditions, people are suggested to change more often.
When one buys a 2nd hand car, it's advised to change all the fluids immediately as you may not know when the previous owner did so (if ever he did).
every 2 years or like what vinj mentioned every 40t kms whichever comes first...may occasional cases na hirap nang mag shift ng gear yung mga naging customer namin kaya ang cheapest and fastest solution nila is magpalit muna ng transmission oil before suspecting any other parts...
