Transmission Fluid - My car is ruined - help

[auxmike]

I don't know, but I'm not messing with mine!
There is a sticker right on the neck of the tranny dipstick stating no need to change the fluid.
Stick to oil changes.....

all that matters is:

Toyota WS is lifetime, no need to change it unless:

it becomes discolored
it becomes burnt smelling


so that basically means you may end up changing it around 150,000
YMMV


what makes it special is: ws stands for world standard and was developed
with the hybrid synergy drive systems in mind. Toyota uses it everywhere now
so there will be less mistakes moving forward, and one simple ATF fluid for all
Toyotas.

it is the only ATF that won't destroy toyota hybrids and electric drive systems

it has a lower viscosity when cold for energy savings,
and lower viscosity at operating temps...the viscosity rises when it gets really hot and then
matches atf T-IV viscosity

transmissions are specifically built for it.

any other fluid can and will cause long term clutch failures, solenoid failures...etc...

My tranny fluid was "discolored" at about 10k, maybe earlier.

I changed it at 60k, when the shifting became noticeably less smooth.
