Dexron III and Dexron VI ATF

[johnjoseph]

Need comments po! Pwede ba mix ang Dexron III at Dexron VI ATF, planning to do another D&F in the near future. Alam ko, back speced ang synthetic Dexron VI sa mga ATs using Dexron III. Pwede kaya D&F lang where it will mix with the old Dexron III or full fluid exchange na? Whiz DIII/M ATF ang gamit ko ngayon.

Appreciate your comments on this! TIA!

dexron VI can be used on vehicles that requires dexron III,
dexron III cannot be used on vehicles that requires dexron VI,

to be on the safe side, do not mix them up, kasi there are certain transmission that are sensitive to the different slippage/viscosity characteristics provided by each dexron series...

Does it mean only a full fluid exchange must be done para no mixing will occur? Sa ATF dialysis ba, hindi mix ang new at old fluid? Thanks sa input, miko101130!

^ Yup, you'll need a full fluid change. The best would be to do a dialysis IMO.

bro, best talaga ang fluid dialysis... once every 60,000kms lang naman gagawin kung regular driven ang auto.
sa atf dialysis meh chance mag mix ang new at old pero konti lang naman... kasi one way flow yung fluid so mag -tap lang sa lines para yung papasok galing sa new at yung lalabas eh mapupunta sa container...

if im not mistaken, sa atf dialysis, you can achieve 90% efficiency sa pag palit ng new against the old...

just a reminder if ever mag atf dialysis ka, kung example 10 liters and laman atf, magdala ka extra 2 liters para totally ma flush luma, mahirap pag saktuhan lang dala fluid... and never accept the offers na need mo maglagay mga ATF additives!, or any other stuff except the atf fluid itself.... its best na dala mo agad na yung atf na gusto mo... keysa sa shop ka bumili that way you decide kung anung brand at anung quality ng fluid ang gagamitin.

And if your ATF is really bad, you'll need more than 2litres extra. I bought a 1997 Corona Exsior in 2006 from an elderly lady who did not change the ATF eversince she bought it brand new. (mileage was only 50,000kms)... it took us 20L of ATF to get the system cleaned out. But it was worth it as we never had problems with the AT until we sold the car.

The atf is still clean because I installed an inline spin on lube filter, B173S, after the radiator cooler going to tranny sump. Am using Whiz Dexron III/M now, just want to try any Dexron VI atf, I thjnk synthetic grade na ito, thinking might improve the performance and prolong the service life of my tranny. Wala naman problem, baka lang gumanda pa hatak with new type of atf.

bro, yung inline filter mo na baldwin hydraulic type ba yan?
kasi before sinubukan ko din install ng inline filter sa atf line, pero meh back pressure... kasi mataas resistance nang filter media sa hydraulic fluid, so mag decrease ang volume na makaka balik sa sump, at more often mag by-pass mode ang tranny.

Lube filter din ang B173S, with 20 psid bpv pressure setting. Alam ko, mas low viscosity ang atf than motor oil, so it can pass through easily sa filter media at ang filter head na gamit ko ay fuel filter head with pump kaya once na dumaan sa orifice with one way flapper, nowhere to go ang atf but to the sump, alam ko, zero ang pressure doon. Using this for more than three months na, so far, nothing unusual ako feel sa tranny, maganda pa nga performance ngayon. Kung may back pressure, magkaroon ng leaks sa mga clamped hose, wala naman, malinis at dry lahat, wala din enlargement ang hose from the cooler to the filter.

Sa looks ng atf, tested using white napkin, absorbed kaagad ng napkin ang atf from the dipstick, without residues left, very clean, no particles that can be seen, the color is the same as when it was first poured in.

Anyway, that also comes into my mind, to use hydraulic filter for atf, still looking for it, wala stocks sa mga suking dealers. Yun sana BT223, 3/4" - 16 thread, magpapalit naman ako ng filter head na mas mahal, M20 x 1.5 thread kasi ito nahingi ko filter head ng maisipan ko DIY ito.

madalas kasi yung mga hydraulic filters ay malalaki in sizes... to account for pressure differential kaya before wala ako makita sa kahit anung brand,

[johnjoseph]

BT223 and BT310 are hydraulic filters, we are using them as oil filter, depends on bpv settings needed. I think hydraulic and lube filters are just the same, maybe, big filters are for high volume and pressure applications.

bt223 din gamit ko as an oil filter sa feroza ko........ baka pwedeng pa post ng pics ng diy atf filter set-up mo sir.

I'm sorry, tablet lang gamit ko ngayon, nasa hospital pa ang desktop pc ko, pero meron ako posted pictures ng diy atf inline filter ko sa transmission forum here, backread mo na lang doon...

BTT...read some thread sa transmission talk forum ng BITOG, most comments, pwede mix ang Dexron III at Dexron VI atf, D&F pa recommend nila para slow transition and cleaning ng tranny. Slowly replenish the additives of old sheared atf, mas maganda daw compared sa full atf exchange by pressurized machine.

Any recommendation on available brands of Dexron VI atf sa market natin...

Questions mga sir

1. Anyone here na regular users ng shell spirax dex 3 fluid? Sulit ba ang 300petot per liter nito
2. Have an atf spirax na opened na for one year, asa trunk lang. Can this still be used?

[johnjoseph]

Did a drain and fill yesterday, drained 3.3ltrs, wala na patak kaya plugged ko na. I used Caltex Texamatic 1888 Dexron lll, that's 45% New ATF in my tranny, plan to do this every 6 months, same OCI as my engine oil, hindi na kms ang susundin ko interval, daily driven at hindi umaabot ng 10k kms a year, hindi na siguro shortchanged ang car ko sa ganito.

Nag-improve ang shifting, 1.8k rpm, shift na siya, dati, umaabot ng 2k rpm, acceleration improved as well pero hindi na katulad ng medyo bago pa, satisfied na rin ako dito.

Sa Caltex gas stations, meron nun. Mga suking auto supply selling motor oils, meron din, Valenzuela area ako.
