Transmission Oil

[ipd]

Generally for ALL vehicles, whatever the OEM specified transmission fluid is...when supplanted by a newer version of said oil...the newer oil will have to be backward compatible with all older vehicles using this type of oil.

In any event, I've been using Valvoline full-synthetic for many, many years on various vehicles...and have zero complaints. Now bear in mind that I'm religious about changing it every 15,000 miles.

I do not have experience with "AFT Maxlife" and can't speak to the pros/cons of it vs what I use. Always full-synthetic, never blends. Same reason I use Rotella-T6 for the engine oil.

Your VX has very low mileage, so there's virtually zero reason to stick to conventional oils. NO conventional oil will ever outperform a quality synthetic oil. There's a lot of science behind that, which includes homogenity, sheer-resistance and a load of other technical things that are the cure for insomnia. I have no slippage with mine, btw, and I'm about to tick the 100k mark in the next several months. In fact, the only problem I think I have with my trans is the"GM standard roar" from the rear differential. Probably has to do with mileage wear/tear more than anything. But the trans itself shifts great and doesn't slip.

Thanks for responding to my post. Do you do a flush? I'm thinking a flush would be OK since mine was flushed 18,000 miles ago.
Do you also do a filter change every 15,000 miles?
