Truck was running fine till I change its manual transmission fluid and poured Toyota 75w90 . After fluid change gear started making grinding noise when accelerating. Noise is really annoying one . Please advice as mechanic said gear is gone with the wind needs new gear box . @rajaatta @Xulfiqar @danikk
What did the oil container say on it? I beleive you need an actual API GL4 oil in it. GL5 causes gear clash. - and whine is usually due to low gear oil level.
Check it again if its full.
Gl4 75w90 7 litres I purchased . Now how to check gear oil level in Vigo champ?
There is a fill bolt, level is checked with that, make sure your truck is standing straight level when you check.
Procedure explained go to the mechanic and recheck it double check by yourself
