The transmission is essentially a sealed system (minus the vent valve). Therefore, controlling fluid temperature and cleanliness will dramatically improve transmission life. CHANGE ATF OFTEN. Drain and refill. Avoid flushing operation. Drain/refill will usually replace 25% to 30% of total fluid capacity.
Idemitsu is, and has been for decades, an official O.E. supplier of engine oils and transmission fluids to leading Japanese vehicle manufacturers such as Toyota, Subaru, Nissan, Mitsubishi, Mazda, Lexus, Infiniti, Honda and Acura.

Idemitsu ATF is being discussed as a close match for Toyota WS and other Japanese automatic transmission fluids, with the main appeal being inexpensive drain and refill maintenance rather than a full flush. The strongest guidance favors changing fluid often, replacing only part of the capacity each time, and keeping the transmission clean and cool. The main caution is that very old fluid or worn clutch packs can make a fresh change feel slippery, so gradual drain and refill steps are preferred over flushing. It is a practical low cost maintenance fluid for careful service intervals.
Common Questions (6)
WS is commonly used as a drain-and-fill replacement for T-IV and can work without issues in many Toyota transmissions. It is thinner than T-IV and not officially treated as a direct backward-compatible substitute, so a cautious partial drain-and-fill is the safer approach if you choose to use it.
Drain-and-fill is the preferred method here; flushing is repeatedly discouraged because it can dislodge debris and abruptly change ATF friction properties. A drain-and-fill typically replaces only about 25% to 30% of the fluid, so repeated partial changes are used to refresh the fluid more gradually.
A frequent schedule of about every 25,000 to 30,000 miles is recommended, with some owners doing 1 quart at a time until the fluid looks clean. The idea is to keep the ATF clean and stable rather than waiting for very old fluid to accumulate heat and contaminants.
Fresh ATF can sometimes reveal or worsen slipping in a worn clutch pack because old fluid has more friction. For very old fluid, a gradual 1/2 to 1 quart drain-and-refill with a short drive between changes is suggested to reduce the chance of a sudden friction change.
Idemitsu Type H-Plus is described as close to Honda DW-1, but not identical, and some newer Hondas may not accept it well. For the least risk, OEM DW-1 is the safer choice; Idemitsu is more of an emergency or budget alternative.
Use an IR thermometer or temperature gun and target about 105-110°F at the bottom of the ATF pan, with the car level. That temperature window is used to set the fluid level accurately during the drain-and-fill process.

Idemitsu and Iran back then!!!!!
Auto transmission works on fluid friction. Old fluid has more friction. Fresh fluid may cause slippage. Toyota Aisin transmission is quite robust. WS is backward compatible to T-IV.
If the transmission does not slip, then drain only 1/2 to 1 qt and replace the EXACT amount drained with WS. Drive 500 miles to check for slippage. Repeat every 500 miles until the drained fluid is no longer dark brown.
Valvoline Maxlife ATF is compatible with the Mazda blue ATF FZ! Note that Mazda may decline warranty if you use the red Maxlife fluid. That said, I have only encountered positive outcomes with Maxlife ATF mixed with FZ.
The Toyota (conventional + E-CVT) and Mazda (conventional + E-CVT) transmissions are very robust, unlike those from Ford, GM, and Nissan. Give them clean fluid and they will give you may years of trouble free service.
