Hello all,

Anyone know if it's ok to use the Dexron III/Mercon to do a drain and refill. Advanced Discount Autoparts guy says it is.

thanks Jamie

 

What's in it now? Is it Dexron IV?

 

Haven't used or even heard of that so can't help you there.

However, if you're looking at transmission oil change, I've heard nothing but great feedback on BG Syncro Shift or Redline.

I like the Scot Gray mix which is 2 quarts Redline then top off with BG syncro shift. Comes up to just the right thickness, or at least it feels that way.

 

I don't know what was in it. We bought it used and the acura dealership where it was did a full service on it before selling.

I've also heard good things about redline and amsoil products... real popular with the diesel truck guys.

Where can I find these brands of ATF? Local stores or do I have to order it?

Just get a tranny fluid that was designed for synchro transmissions, it will say right on the label. They are sometimes hard to find. If your tranny is quirkey/hard to shift I would get BG synchroshift. I believe you can buy it at a GM dealer. Its literally a new tranny in a bottle I never thought a fluid could make such a difference.

 

Noooooooo..........

Mitsu cars 2000 and up use ATF SP III fluid. This is a proprietary semi synthetic blend. It is used by Mitsu, Hyundai, and Kia. Do not use anything unless it says it is SP III. It is only available at those dealers. I hear it is cheaper at Hyundai and Kia.

Amsoil claims that their fluid is SPIII rated. I would just pay the bucks and use the Mitsu or Hyundai fluid.

Prior to 2000 any Dexron III fluid is acceptable.

 

I just noticed that he has an auto tranny, so forget what I said. My statement still applies to all synchro manual trannies.

 

Mercon/Dexron III and Dexron IV are transmission fluids commonly used in most auto trans cars. Kia uses a special type of trans fluid (The shop I work at carries a few quarts just in case).
