Transmission fluid
You change transmission fluid every 3 years
While 90k is only 54,000 miles, ten years is how
old my lincoln is & I changed mine 3 times & it should
have been 4 times
You go by years, not miles anymore
Time used is heat cycles & the fluid will only last
for 3 years including 2 hot summers ,then it won't
remove heat & you trans clutches fail
You have to use the NEW Matic S from a nissan dealer,
as no other fluid is correct for your jatco trans at this point
in time
You add one ten oz bottle of red Lubegard to ALL your vehicles
transmissions with every change
You DO NOT FLUSH a trans as the fine debrib could get
into the solenoids
You have to add a return line filter at the cooler in front of the radiator, because your trans has NO Filter, only a screen bolted to the valve body
Same trans as my 3 week old 2014 Frontier
What you read was IF it was slipping & you change the fluid
it will slip worse,in that case the damage was done already
Ten years is a death sentence to any trans
Change it anyway,not many miles on it
Don't change it if you got shifting problems you don't want
to discuss here & that is why your here
You remove the pan on the bottom of the trans
Wipe it out,clean the magnet & you should have a
fill tube & stick next to the motor to add the MATIC S
Fluid
The return line filter will be your ONLY protection for that
Nissan trans, as a screen is not going to stop anything micro
scopic particles ,nor will a regular filter on most transmissions
You get a Filtran Magnetic Return Line Filter & install
that on the line that goes from the surface to air cooler to the
trans case
The other line you can see goes to the radiator first, then to the
out front cooler,that is the hot oil pressure feed,your putting
you little round filter in the other return line
You can put one of them on the power steering also or change
a steering rack when it fails
Have to do that or new racks are not warranteed
