mercon v vs. amsoil atf

[tim marks]

im fast approaching the time to do a trans flush on my 96 gmq. ive been told as well as read that i should only use mercon v fluid when doling so. on the other hand i have also heard that amsoil atf should do the trick as well. i was wondering, in your guys' professional opinion, if i used the amsoil atf would i be making a mistake? if it makes any difference, this will be the first trans service the car has had to my knowledge. i plan onj doing the jmod at the same time. thanks for any replies.

Mercon V was specially designed to deal with the torque converter shudder issue during the mid 90's.

I like Amsoil. I wish I had enough money to use their engine oil right now. But I personally wouldn't use their trans fluid. It covers too many applications to be of benefit to Mercon V transmissions.

IMHO.

What he said. I'd use the Ford reccomended fluid for the trans. Its a semi-synthetic fluid, and it was designed specifically for the 4R70w and AODE trans. Its actually what they suggest for the AOD these days too.

Lucas makes a semi-synthetic transmission fluid now as well, and it meets the requirements of Mercon V. If we carried this when I did my fluid change I would have used that instead of Valvoline Maxlife with the Lucas treatment.

personally I'm not a fan of adding any sort of treatment to an engine or trans unless its really needed. If it works fine, I run nothing but virgin fluid in the system. I will dump some magic in a bottle into something thats dying though, just to see if it helps it or to squeeze some more life out of it.

Amsoil ATF is not a treatment. It is a fully synthetic ATF that I have heard nothing but good things about. I have heard that it behaves better in finicky Honda automatics than the Honda stuff that you can only buy at the dealer.

edit: realized you were talking about the lucas treatment, not amsoil atf.

im picking up a case of Royal Purple Synthetic MAX ATF for the Marauder after work.
I'll let you know how it turns out. And it's not for the faint of heart. $118 a case. But so so so worth it!!

ive heard some rumors of royal purple not being all its cracked up to be, let us know how you like it though.

Well my friend Mike used to run Mobil1 full-syn in his '99 Cougar, but he recently switched to the RP and he's told us it shifts even a little smoother than it did with the Mobil1.

Personally if I was to build up an AOD for my car, I would probably run a good full-syn Mercon V.

yeah, it was $171 a case. it asked how much it was a bottle and they said $16. Then i said "but it says 11.49 on the shelf?" And guess what. i got it at 11.49 a bottle. for a case. so i got $22 off a case. and it all goes in tomorrow. I'll give an update once i can take it for a drive.
