The Camry is fast-approaching 60k and I wanted to change out the tranny fluid (just because; it's specced as a lifetime fluid). The Camry has a sealed transmission with no dipstick.
It shifts well; it sometimes has one strange shift when cold, but nothing other than that. Anyway, I wanted to be proactive on maintenance.
Essentially every shop I called wanted to flush it, in addition to adding all manner of strange chemicals (conditioner, "cleaner", etc.)
They were looking to charge $250-300 to do so, including the dealers (none of whom wanted to or recommended doing this piece of maintenance).
I did find a smaller shop that was willing to do the work and only bid $60 for the first change, and about $100 if I wanted to do two.
(The guy said that doing it twice wouldn't be necessary but would depend on the condition of the fluid.) He uses "Medallion ATF" in bulk from a local distributor:https://medallion-plus.com/user/products/pds/to-14-01-29-18.pdf
It lists Toyota WS as one of its "approvals" but I can't find much out about it.
Any concern letting him do so with that fluid? Or should I bring WS or some other ATF in bottles? He said that it'd cost $45 or $85 for the two changes if I brought fluid.
(If I bring fluid, should I bring Maxlife or some alternative, or stick with WS?)
