Toyota Belta Automatic gearbox slipping

Hi, I was just wondering of someone could help me because my 2007 Toyota Belta automatic transmission sometimes the gearbox slips. I thought of changing the the gearbox oil will this make any improvement.

Thanks for you help

Usually once an auto starts slipping it is too late for a fluid change to help. You can try changing the fluid and the filter, but you are likely looking at a transmission rebuild or replace in the near future. How many miles (or km) on it?

Hi,

Thank you for your help.
My car has about 135000 km.

Thanks again,

That's young for a Toyota tranny to fail, but it all depends on how it was treated up to that point.
