I have heard on the shade-tree mechanics talk radio shows about a product by Lubegard. They swear by the stuff. You may have heard the advertisement.... no more whale oil production so they had to come up with an alternative.....all transmission repair shops use this product to backup their warranty... They claim it just can't be beat. Of course I know they are getting paid to endorse the product. Lubegard product line covers additives for oil, tranny, and power steering. My father had a "gittery" transmission when in overdrive. We pulled into CarQuest, bought a 2oz. tube of Dr. Tranny, installed it directly into the filler tube and it has never "jittered" again.
Their major competitor is the Lucas product line.
What do ya'll think about these additives being used in a PSD? Has anyone tried them?

 

I don't like additives. I feel they mask more problems than they actually fix. There was a study done by DuPont that someone posted on here a little while back that showed that some of the additives (i.e. Slick50) actually do more harm than good. With a good preventitive maintenence regimine there should be no reason to add these chemicals to your rig. The exception being a high quality fuel additive, because we all know you do get some bad fuel every once in a while and some fouled injectors. As far as oil and tranny additives it is my opinion to steer clear.

VERY GOOD article. Very convincing and thought provoking. Thanks a bunch

 

A lot of people swear by the Lubriguard products. I am not sure that they are any better or any worse then the other products out there.

Some additives will help under some conditions, but with the heavily modified oils and ATF's now, extra additives really aren't needed.

The only thing that I might use is the fuel additive, but Stanadyne and PowerService are good products too.

 

I have used Lubegard in my son's 94 T-bird auto trans. It has a factory built in torque converter shudder! Even after changing fluid and filter, etc., the only thing that cured the shudder was the Lubegard.

 

So it actually "cured" the problem? I'm sorry but I am a skeptic, I really can't see how a liquid can "cure" years of wear on metal parts and pieces. Notice I said metal. I do agree that you can help with seals and such made of rubber(of sorts) that have dried out, but I am stubborn and hard to convince.
Hey but if you want to use it that is entirely up to you. I personally want to fix the actual problem while it is minor (hopefully) instead of prolonging the inevitable and possibly costing a lot more down the road. (down the road, get it, trucks, cars, drive down the road, I crack myself up sometimes, good night gracie)
Just my opinion

Well at least somebody thinks it's funny.

 

I agree it's better to fix, but Ford doesn't have a fix for the lockup shudder on the T-bird. Whatever additive is in the Lubegard for the trans, makes lock up firm. But other than that and Diesel Kleen, I don't use any additives in anything. Just modern day snake oil sales gimmicks to me. Syn oil? I've used Royal Purple in the race car. I can tell there is less friction than conv oil. But not enough to justify $4.99/bottle compared to $1.70 for Valvoline Racing Oil. Just MHO. Especially when I change the oil every 2 weeks!
