LOLing in this particular case was uncalled for. The tranny is not sealed and the ATF can be changed. In fact I have yet to see a truly sealed transmission, where the only way to change the fluid is to split the case

Amsoil Low Viscosity formula is good stuff, running it in my camry and my transmission likes it.

Sorry but what is a BG Transmission Service?

I took the dipstick out of my transmission, put a plug in it, and Voila!... I have a sealed transmission! laugh

Sealed doesn't help the fluid any. Change it... at least to get rid of the break-in debris.

It's sealed for one reason to discourage DIY.

Those machine do a good job, but they are a tool to sell their additives. Just tell the dealer that you don't want ANY additive, only the WS fluid. They do a better job at exchange the fluid than you could do manually.

I would definitely do it, but I would take it somewhere were they could use Maxlife or another quality LV fluid. WS is well-known to fail more quickly than others (as commented on above). It has given poor life and shifting after a while in both our Lexus and a neighbor's 4Runner; switching to Maxlife improved things and got longer service intervals.

There's no dipstick, but there is still a dipstick tube, as well as a drain plug smile

For $120 I assume it's a drain & fill so only about 1/3 of the ATF gets exchanged.

Between 75k and 100k the ATF should have at least a drain & fill. Filter change also.

Unsure what kind of ATF the vehicle uses. Some OEM ATF is expensive.
