I am about to have my transmission serviced. Does anyone have any suggestions on a good Mercon V ATF. Mobil 1 says that theres does not meet the spec.

 

I just picked up some Castrol GTX merc v. 3.49 quart at autozone. its says its a synthetic blend? or is part synthetic.

 

HI!... REDLINE D4. Been using it now for about 4 years. No problems here.

Looking at the website for the redline, it did not mention anything about Mercon V. Did I miss something?

 

HI!... When I rebuilt my 4R70-W, I called REDLINE directly and was told that the REDLINE D4 was MERCON V compatible. Like I said before, I've been running it for 4 years now with no problems. There are plenty of other guys here on this site running the D4 as well.

 

Redline D4, Amsoil Universal ATF, and Mercon-V synthetic blends/group III ATFs

Here is a another link on the subject.
