Hello Scotty,
Am a loyal follower of your videos. I'd like to ask if Castrol Multivehgicle ATF Dexron VI be ok as an alternative atf for my old vehicle Chevrolet Optra 2004 1.8LS AT (with ZF4HP16 transmission). The manual requires ESSO LT 71141. However, such a fluid hard to find in our area in the Philippines. The last atf used in this vehicle is Castrol Multivehicle ATF Dexron III but such atf is also now not being supplied by the distributor. They only supply now Dexron 6 Mercon LV. Would using the new Castrol atf be ok?
Thank you in advance.
Sincerely yours,
ButchockKoi

Hmm, at first I thought it might be similar to the ZF 4HP18 transmission in my own car that uses inexpensive Dex/Merc fluid but apparently it is something completely different, a fairly obscure ZF model that was developed for Daewoo (which became GM Korea), with ZF turning over everything to Daewoo:

Checking around it appears that Dexron VI is not appropriate for that transmission, you want a fluid that specifically states it is compatible with the ESSO (now Mobil) LT 71141 specification:

A comment in the above forum thread does state:
I've decided to go with either the castrol import multi vehicle ATF or pennzoil multi vehicle atf as they are both locally available and both list that they are compatible with that ESSO number
These are just from some quick searches. Our moderator @dan might have more details.
Thanks. I came across this literature from castrol site. Though Im not sure if the LT 71141 is the same as required in my car. Does'nt mention esso
Hello @dan
I'd like to ask your expert opinion if using Castrol Transmax Dexron 6 may be used for Chevrolet Optra 1.8LS AT (with ZF 4HP16 transmission). Im afraid using the inappropriate atf may damage my transmission. Thank you in advance
Hi
If the fluid manufacturer lists the correct specification under “product performance claims” of this product - then sure.
(I think it’s just Dexron III for these…)
-
You can find the correct fluid type in your manual in the “specification” section.
-
Additionally, you can just call and ask your dealer - then go buy that fluid elsewhere for cheaper.
