A/t or M/t FLUID? ATF or GEAR LUBE (main transmission or the transfer case????????????
auto or stick????????????
we cant guess transmission options
if you have 4wd, it has 2 transmission devices.
the car is A/t it has no dip stick, you looked and didn't say that in your post ,right>?
so it has unique fill plugs, and special rules.http://www.cargurus.com/Cars/Discussion-c2320_ds475902
the 4L30E manufactured by GM.
the old car book shows DEXRON III
mark 3 is no longer made or legal to make, its been decertified.
that means run DEX VI Dexron 6
DEX 6 is downward compatible (and many times better)
it runs hotter with no damage to it . see?
but Dexron is never upward compatible ever. dex3 in new cars never...!!!!
and DEX1 is whale oil so forget that.
easy peasy japaneezy, right.?
if you learn to google you can find out facts like this.
lost operators guide.
or cant find a FSM for 2000 trooper?
they made all this harder so typ, owers will leave to the mech to do this right, many owners burn up transmissions!!!
by overfilling or using wrong AFT or both. vast causes.
ATF means automatic transmission fluid.. if you wonder.
on newer cars the oprators guide, will show
Nothing for transmission service, (like all older cars had)
or will just say get car service, by a professional for all transmission checks.
If really curious, all this is covered in all cars made in the big book, called a FSM ,(SM) factory service manual.
it's all there, read it.
or go to alldata.com, mitchels or chiltons on line. and read the (near) FSM on line.
same answer for all cars made, read the FSM
then ask questions.
if you need the quoted book, steps the link above has it.... from a poster, hope he posted the right pages, and for right car.
using rumor to fix cars is HIGH RISK.
best best is to read the real OE book from ISUZU.
ever price a new transmission..... ???
on even newer cars the level is set using
a scan tool that can read transmission temperatures. (good luck doing that... on your next car)
let me now explain correct. per the trans makers.
they want the pan dropped, and filter new.
they want all that ccrraapp in the bottom of the pan removed, for sure.. and off all magnets there.
the want the right fluid there, not a mix of gawd knows what or some walfart trans additive magic snake oil; melting all the seals and o-rings inside.
they want the newest DEX in there, all DEX6 NOW.
and filled to the correct level hot, never under-filled or over filled.
deleting this dip stick, forces most owners to get it done by a pro, and longer life and no warranty work at vast cost to makers.
that is how the story goes, it's no secret.
this car is and early adopter of this method and I'm sure GM had a hand in this...100%
