DTT full billet trans

[doug60]

My trans builder, DTT has recommended Dexron 3. He specifically told me not to use ATF 4.
Quote (Dexron III is the most aggressive fluid & ATF4 has friction modifiers that will cause the modified trans to slip)
OK heres my question
Schaeffer's all trans & also Amsoil atf both claim they meet the spec for both Dexron III & ATF4.
I'm afraid to try the Schaeffer's in fear that it might cause modded trans to slip.

Either oil will do fine.

By ATF4 did he mean DC ATF+4???

 

[MolaKule]

Is this transmission being used for racing (I am assuming this is an Automatic)?

If so, you would need a Type F.

DexIII is friction modified but not as aggresively as MerconV and ATF+4.

What did your builder do to the modified transmission that would require a DexIII rather than the ATF+4?

 

[doug60]

Yes ATF+4

In that case I would go with a plain-jane DexronIII with a mineral-oil base.

And change fluid at around 15k miles.

I am running 204SAT in my DTT transmission and 89% Torque Converter now - no slippage. Ponies around 380 HP.

Thats good news, I found more info on the DTT forum, Bill states many of his customers are running Amsoil with good results.

No problem Doug. People stick that T in there all the time. Like Dextrose!

I vote FIRST for Amsoil Racing ATF aka Amsoil ART

After you talk with your builder. OR on the safe side:

Amsoil ATF

There you go doug60, seriously, try each one for 10k and report back to us regarding shift quality, shudder, etc.

BTW, we also have a type F that can be tweaked for a particular transmission.

My Bad
There was some confusion, the fluid recomended is Dexron III not Dexron III. This is my first auto.
racer12306 thanks, doug
