Using Idemitsu TLS (Toyota T-IV) & TLS-LV in other applications?

[92saturnsl2]

I went all in on the Autozone clearance of Idemitsu TLS & TLS-LV @ $2 per quart, despite not owning a Toyota. I don't subscribe to the "must use OEM fluids" belief, I've used universal fluids in just about every AT I've ever owned with good results. My assumption is that Toyota T-IV is largely compatible with a Dex-III or similar fluid (non-low viscosity) and that TLS-LV ought to be similar to fluids meeting a Dex-VI or other LV spec.

Is there any solid reasoning / proof that might shoot this theory down? I can always sell the stuff if it's somehow going to poison my transmission.

I was thinking of using the T-IV in my '96 Maxima, and the LV fluid in a 2015 Kia Sedona (6sp transmission) that originally spec SP-IV. Thoughts? If it might work better in another application that's in my signature, I'd be interested in hearing it.

for Power Steering it’s an unbeatable price

as for Dexron III i’d try it what could possibly go wrong

In the owners manuals for the Toyota vehicles that require T-IV or WS, it states the power steering fluid should be Dex II or III. I always thought it interesting that they didn't spec the use of the T-IV fluid so there must be some difference.

I used Red Line ATF D4 in my Toyota that required T-IV ATF, and it negatively affected the shift quality. I went back to T-IV or Mobil 3309 and the shift quality improved. Had a major slip from 1-2.

The only way to know for sure is to try it.

I have a car that requires Dexron III. Idemitsu TLS works fine in mine, and $2 a quart is a steal. My transmission is running as smooth as ever

I ended up using the TLS in my '96 Maxima that original spec Matic D.

I can't tell a difference in shift quality, still shifts good as it always has. The Autozone clearance at $2 a quart makes for a cheap transmission service.

I bought 10 qts of Idemitsu Type TLS-LV (WS) and 11 qts of Type TLS (Type IV) at $2/qt. Should be good for 2012 Highlander, right?

Yes, the LV will work in your Toyota.
