I have been advised to add this stuff to the mercon ATF change in my 96 F150 as it will benefit, long term, as a "friction modifier". Is this more snake oil, or does it help? Other than the guy at NAPA, I haven't found anyone with real experience with this.

 

Mercon ATF has exactly the right amount of friction modifier already in it. If you add more the transmission might slip. Save your money for more frequent ATF changes.

I used Lube Guard additive in my 93 F150 transmission because it appeared the govenor was sticking. Shifting hard between 1st and 2nd, sometimes 2nd and 3rd. This fixed the problem immediately and lasted for several months. Problem just started coming back. I'm thinking of trying another addititve.

 

Maybe you need to consider fixing the transmission?

 

Ideally fixing the problem would be the best thing to do. There are just two things in the way. Money and time. Is the governor a relatively easy thing to change do you know?

 

After doing a little research regarding lube-gard I added it to my 97 with and E4OD to try and help with the torque convertor shudder. I must say to my surprise it seemed to work quite well. Use the lube-gard in the red bottle and not the black. It is the first additive of any kind I ever tried that actually came highly recommended by knowledge people. My shudder is not completely gone but is greatly reduced. By the way where I live Napa was the only place I found it.

 

I also had the torque convertor shudder in my 95. The Lube Guard and a transmission service took care of my problem completely. I had no other symptoms of other problems and there was no signs of trouble when the pan was removed.

Its probably been close to a month now. No problems at all.

I was a skeptic about using it. But I have known my very trusted ASE certified trans mechanic for years and he had never led me astray before, so I trusted him on this and it worked out just like he said.

 

At one point, years ago, SAAB had a technical bulletin recommending it
for the ZF automatic transmissions. I used it in my Alfa Romeo since
it uses the same ZF tranny as the SAAB and have had no problems in 150,000 miles...

Has it helped? The ZF transmission used in these cars is noted for
having problems so perhaps it did. I could tell a difference in shifting.

They also offer a very good engine flush for 7 dollars . It is the best I've ever seen/ used at any price .

Good idea for any engine every once in a while just too bad few have heard of it and the technology behind it. It is sold in NAPA stores but my area stores don't stock it so I bought direct " a small case "

I used the other Lubgard for the Dexron fluid in a GM trans that the torque converter was staying locked when coming off the hi-way....one year layer all's OK
