2018 Yaris iA - Changing the ATF? - Toyota Yaris Forums

lorne · 08-26-2020, 02:47 PM

As a follow up on my last post: the AT pan was pulled on my 2007, 1.3L 4WD Vitz today. These transmissions that nestle with a transfer case that shares the ATF with the AT do not have a filter — only two small magnets in the pan. This ex-rent-a-car with 167,000 Kms on it possibly had only one ATF drain in its history. And, that was at 144,000 Kms.

Today it was found that the pan was dirty with contaminants. This at least must partially explain why a previous 5 Litre drain 20 Kms later was showing black traces.

This service was precautionary, because I intend this vehicle to run flawlessly for years to come — even though it guzzles fuel. So, my humble advice is, if you own one of these models, pull the pan and change the Toyota ATF T-4 fluid if you have not been doing scheduled drains. If you don't intend to make the machine last — well just grind on.
