I know this has been bandied about ad infinitum but I am looking for an objective data point here.

Has anyone changed their transmission fluid to anything other than the original Jatco fluid and then put a substantial amount of mileage on their car? I have found no fluid that specifically meets the Jag/Ford spec (WSS-M2C922-A1). I have emailed Mobil 1 and Valvoline and they extol the virtue of their product with the caveate that I should follow the manufacturer's recommendation. So, no help with the question of compatability and spec.

So, anybody with a good experience with aftermarket transmission fluid?

 

I've changed it many times and used dextron VI with no ill side effects

 

Thanks for the info. What specific brand of Dextron VI did you use?

When you changed it, did you just drain and refill the amount you drained or did you attempt to flush out all the original fluid?

 

thats a good question. did you flush it 1st? and how long since the flush?

 

 

Not to complicate the subject but I have also read where people have used the castrol import multi vehicle blend that you can find at any car store! Any comments

 

Sorry, had to sober up....
I completely drained it by disconnecting the cooler line and forcing all the fluid out, to include the torque converter. Takes approx 10 mins or so. Completely drained, it takes apporx 9 qts. (8.3 or something like that)

I think there is only one version of Dex VI

 

lmfao...I thought we'd have some progress after a few months, but alas it seems not.

Lol, Dennis used to give these real nice long explanations of our current debacle, I see he's reduced his response to the weekly tranny fluid inquiry with just a picture!

 

I written several LONG and very detailed explanation on how to do this process....not really in the mood of redoing it all......do a search, it should be all out there in cyber world!

 

LOL...My tranny is working fine right now (knock wood)..and I don't trust anything oranyone is saying...untill I see bonifide proof..Walmart ATF VI must of been made by someone..to just say it is only one brand to cut the mustard ain't working for me....JATCO is a fussy POS and I'm not doing anything till I see what, who, when and whythe XYZ brand will work..

 

So go to the Jag dealer and get the "Jag" Fluid.

 

Yeah, I'm afraid you're right..to be safe..[&:]

I wish I could find that stuff besides at the dealer though..[:@]

 

Walmart sells whatever brand is cheapest. Look for DEXTRON VI there can only be one.
