Dexron III

[ccdhowell]

I'll try to avoid the "what should I use?" or "Which is the best?" mentality.

I need to drain the trans on my Land Rover with a ZF 4 speed auto. It calls for Dexron III.

I wanted to use the very best Dexron III I can get. I've looked into Motul, Torco, Redline, Mobil 1, and several others.

Any comments/suggestions on what is the very best in Dexron III atf for the German-made ZF? It is a really smooth, positive shifting transmission already, this is just regular maintenance.

I'm not flushing the entire trans, dropping the fluid from the pan replaces about six quarts.

I only tow light loads and off-road this Rover about monthly.

I'm leaning toward Motul, for no particlar reason; it is priced pretty good though.

I'm looking for longevity and cleanliness.

Thanks for your suggestions.

The best Dexron-III fluid would be a tie between Mobil 1 or Amsoil, at least in my book.

If longeivty is a concern, I'd drain the pan yearly and add an auxilliary transmission cooler.

Hi

I would use Dexron VI if you can get it.

Does anyone make that in synthetic yet?

 

[unDummy]

For longevity, use an additional ATF cooler.
For cleanliness, install extra filtration.

Any full synthetic ATF is good enough.

I wouldn't use the thin Dex6 in a transmission calling for Dex3.

And, since most synthetics are multivehicle, I wager that a TES-295 ATF would be the 'best' for a Dexron III application. Delvac/Syncon/Transynd/Donax/TorqueDrive synthetics are some to consider.

ditto what undummy said with one exception; I would have no reservation with substituting the Dex Vl for Dex lll.this link http://www.petro-canada.ca/eng/prodserv/lubesgreases/6886.htm the second link under automatic transmissions.good luck

lewk, Dexron IV looks like a definate improvement. Since PetroCanada is the only ones making it now, it will have to wait till my next drain and refill in November.

Thanks, good info.
