Automatic Transmission Fluid

[jhdeval]

Since the question was asked what type of oil to use in a manual transmission I figured it couldn't hurt to ask about an automatic. Do you use just regular ATF? I am currently using ATF.

Whatever the current version of Dextron/Mercon is what I use.

i use type "F" in the hotrod and truck and "D/M" in the van and suub.

Synthetics are more expensive, but they hold up a LOT better than conventional fluids, especially if you run them hard. I use Amsoil Supershift in my race car's 904 and their Universal ATF in my 2004 Dodge diesel tow truck as well as my everyday Dakota.

See here. Everyone's got an opinion, and Torqueflites are tough enough to withstand all kinds of abuse, including the use of non-optimal fluids. Me, I stay away from Scamsoil; their stuff is overpriced and overhyped, a lot of their claims are baseless, and I don't like their Amway-style pyramidal sales force of "dealers"

Can you mix dextron II with dextron VI or do you need to use the dextron specific number you have in trasmission now ? What if you have type F in it can it be mixed with dextron ?

 

[slantsixdan]

Can you mix dextron II with dextron VI

Yes, without any problem. And there is no "T" in "Dexron".

What if you have type F in it can it be mixed with dextron?

Yes, but this is less optimal.

Type-F ( 904 with a Trans-Go TF-1 )

The one that gets me is seeing these cheap *** shops that use DEXIII-MERC in new(er) transmissions :cwm10: . They must like rebuilding transmissions or something !

One dumb *** shop in particular filled a 518 with DEXIII . I told 'em that they'll be doing warranty work in about 1 week ; they scoffed and told me "it's all the same" ...

... 2 days later , that truck was back in their shitty shop for warranty work , as the trans fried !

Stepping-over dollars to pick-up pennies :tongue1:

And , we have a buttload of leftover Plus 3 fluid that we would've sold to 'em for next-to-nothing as it's old , outdated stock ( how long ago did Plus 4 come out ??? ) .

thought so , but looked at abpove posts and they spelled it dextron , thought I was mistaken and changed it


Yes, but this is less optimal.
