I am looking to change my transmission fluid in a series of 3 or so pan drains and refills. I see its pretty unanimous that dex 3 is the way to go even though my FSM says dex 2e. Then I read a tsb that says atf+4 is now approved for the aw4.

I'm not the original owner and i have no idea whats in there now. Is there any danger in possibly mixing different types of atf without a complete flush in a series of pan drains?

 

Dex only. No worries.

 

really? i run atf+4 and havent had a problem yet. should i be expecting anything? only been in for about 2k

 

Many folks have experienced slipping and other issues with +4.

 

at wally world, I see where there is a dex VI. It says its for use anywhere that calls for dex II,III,IV, or V. is this safe in the aw4?

 

Google it. I believe it's a synthetic.

 

Yes it is synthetic.

 

I thought so. It will work fine. I've used synthetic in aW4s before with no issues. It's the aTF+4 that gives issues. But, Dex 3 is cheap and works well.

 

I need to flush my trans as well and swap the factory 2 row out. I have a real nice trans cooler from another project that never got used.
