I have an 8-speed Aisin trans in a 2019 Jetta 1.4L that will need a full fluid fill. The G053001A2 is the current recommended fluid for this trans but it's really pricey. I have a liter of Ravenol T-WS Lifetime fluid (G055540A2 spec) and liter of Ravenol T-IV fluid (G055025A2 spec, replaced by T-WS Lifetime) on the shelf previously purchased for a 2013 Jetta with the 6-speed Aisin trans. Are these two fluids close enough to use on my current 2019 Jetta? I know it's only two quarts but it'll save me $50. And $50 is $50. I don't know much about the 8-speed Aisin in this 2019 except that it is new to the Jetta in 2019 and it's used by some other manufacturers as well.
