No, he said broken component. The transmission.
Where to start?
Reduced viscosity doesn't suddenly prevent it from driving. Fluidity? The state of being a fluid? It it didn't have fluidity it would be a solid. The opposite of reduced viscosity. You appear to be suggesting that it has both properties.
Anti foaming is a fair comment. Doesn't just happen in one day though. Yes, that can affect shifting. But to suggest that it suddenly ran out of the additive package and then wouldn't drive at all is a stretch. Don't you think those shops that looked at it saw the fluid? And if it was suddenly foamy that they ignored that?
If the fluid stopped lubricating (very unlikely, since oils never stop being slippery, and the lubrication requirements for a transmission are very low) then internal components would wear to the point of failure. New fluid wouldn't help at all, until after the transmission was rebuilt. Needless expense.
Why would the gears need to catch? They are permanently engaged planetary sets.
In short, the suggestion to change the fluid after the transmission has stopped functioning is misguided at best. Adding in a recommendation to use a specific fluid is the definition of blowing smoke.
I am glad that you have become a supporter of the site. But in your zeal to promote your products, let's not suggest that posters waste money.
