At this point (as far as Jan 2011) there is not any fluid approved by Toyota or Lexus that can replace it. Valvolile and other brands "claim" it is compatible. I had seen transmission developing problems after 4,000 miles when serviced with other brands besides the original Toyota WS fluid. The price difference is none, the savings are none, the damage to the transmission is questionable , the warranty immediately voided, the looser, the owner of the vehicle. Stick for now with original Toyota WS. Google T-SB-0006-11
Toyota ATF-WS (World Standard) Automatic Transmission Fluid used in certain 2004-2008 vehicles is NOT compatible with Toyota T-IV or Dexron ATF. WS ATF was introduced to reduce maintenance costs and increase the mileage between scheduled maintenance checks. The recommended maintenance interval for INSPECTION is 100,000 miles; ATF-WS does NOT require any flushing or changing during the life of the vehicle.
No it is not. You should be OK with any fully synthetic transmission fluid. But look on the back to make sure if it covers WS.
My 2004 AT uses Toyota Type IV.Mobil calls it 3309. I'm not sure when Toyota made the change over to the five speed AT. Look in the owners manual or call a Toyota dealer.
yes, they are equivalent
YOU can't! DO not use anything else but Yoda WS ATF.
Answer:According to a Toyota Technical Service Bulletin dated 6/28/07, 2004-2008 Toyota vehicles equipped with automatic transaxles using ATF-WS does NOT require any flushing or changing during the life of the vehicle. Inspection of the fluid is recommended at 100,000 miles.Toyota also states that ATF-WS is NOT compatible with Toyota T-IV or Dexron ATF. Should a fluid change be necessary, a special service tool to fill the transmission is required. The bulletin also states that containers of ATF-WS should always be sealed, otherwise the fluid will absorb moisture and potentially cause shift concerns if used in operation.Although I personally use Amsoil motor oils and transmission oil for my own vehicles and believe it's a great oil, for a vehicle using ATF-WS, I would stay with that and not change to Amsoil due to the warnings about incompatibility with the T-IV and Dexron types of fluids. Because of the hygroscopic nature of the ATF-WS, it sounds like the basic chemical composition of the oil differs from the typical transmission fluids. I don't have MSDS data at this time, but it would be interesting to do more research to find out. If there's any potential for abnormalities in shifting, and until Amsoil makes a product that specifically meets the ATF-WS specs, I would say it's best to stick with the manufacturer's (Toyota's) recommendation, especially in this case.AMSOIL recently reformulated their ATF fluids and does recommend their ATF for your vehicle:2004 TOYOTA 4-RUNNER 4.7L 8-cyl Engine Code 2UZ-FE LUBRICANTS & FLUIDS:Automatic Transmission,A750F......WSLow Viscosity Synthetic ATF (ATLQT)Automatic Transmission,A340E......TIVSynthetic Universal Automatic Transmission Fluid (ATFQT)Automatic Transmission,A340F......TIVSynthetic Universal Automatic Transmission Fluid (ATFQT)Automatic Transmission,A750E......WSLow Viscosity Synthetic ATF (ATLQT)
It would be Toyota type IV or WS fluid. Recommend you purchase from the Toyota dealer. The Toyota dealership parts store can tell you which one is for your model / powertrain. Type IV transmission fluid (possibly Mobil 3309 ATF) Mobil 3309 meets Type IV requirements. Not sure which company and type the WS ATF is. I would assume Mobil Oil as well, but is a different transmission fluid from Type IV.
Every thing I have researched says yes. There was some confusion as to it being compatible with Dextron by some dealers and auto stores. tHAT HAS BEEN PROVER FALSE AND IS NOT DEXTRON3 COMPATIBLE. But the Toyota T-IV can be replaced by the Max ATF from Royal Purple.
Toyota Tundras that use the E750 or F750 transmission use ONLY ATF with the "WS" designation commonly called JWS3324 in the Toyota manual. DO NOT MIX or substitute any other type.
you dont..it has world standard atf....(ws)...you must check the line pressure to check the fluid......have it done by a pro...t
no. That Jeep takes atf +4 and nothing else. ATF +4 and dextronIII/mercon are not compatible
