Add Lubegard red at every fluid change ?

[2013ecof150]

I’ve done partial fluid changes in my 10r80 every 30k on my F150 using a battery operated fluid pump to empty the pan. Usually pull out somewhere between 5-6 qts. Total capacity is about 13 qts.

At 30k I drained and filled. No additives

At 60k I drained and filled and added the whole 10oz bottle of lubegard red.

Almost at 90k now and will be draining again soon.

To keep the same concentration of additive, am I correct in adding just shy of one ounce to lubegard to every new qt of fluid that I pump in from here on out?

I don’t want to overload it with additive, but it definitely seems smoother with the lubegard.

I do 1oz/Qt with my 10R80, I also use Platinum. I Initially started with a 10oz bottle somewhere around 10k, and have done the 1oz ever since then. It isn't going to build up in the system since you're draining out an equal amount of it when you do the D&F.

Sounds right to me.

I had considered using the platinum, but I’ve only used the red before.

I used Red in my Honda's but when I got the 10R80 and emailed LD, they said Platinum, so I switched everything over to that.

I know there is pushback here on the extra FM's in it, but so far everything has been great. I use it with Maxlife in the Honda's.

I also tow 6200# on a fairly regular basis, so I'm not being easy on it.

Same for about 10 or so vehicles that I've put it in thus far, the platinum seems to be working great

Just add the amount to keep the concentration right. Less is more. Err on the side of adding too little.

Yes, it sounds as though you are doing this correctly. LG RED is designed to be used as; 1oz LG RED per qt. ATF

1) When first using LG RED, you add the amount of LG RED in ounces to the total amount of quarts of ATF that the tranny holds.
i.e., If your tranny holds 10 qts of ATF, then you only add in 10 oz of LG RED.

2) From there after, you only add the amount in oz. of LG RED to the amount of qts. that you've drained & refilled.
i.e., If you drain out 5-6 qts then only add in 5-6 oz of LG RED.

This is exactly what I thought, just wanted to be sure. Thanks to all who replied!

In any 4 speed GM trans please do your transmission a favor and skip the friction-modifying additives and stay far, far away from Dex VI (Dex 6). Yes, GM states you can use Dex6 in DexIII applications, but this is wrong with many early torque converter failures in 4 speed units after using the thinner, friction modified fluids! The PWM torque converter clutch will slip way too much as will the vulnerable 4th gear, which is overdrive, and is the weakest gear in those units. Please stay with the higher viscosity, less friction modified DexIII/Dex3 fluids, which start life as 7+ CST viscosity. If towing, or hot weather or other HD app, consider an aux cooler or a full syn Dex 3 like TES-295 spec, made for HD Allison units. If using non-syn Dex 3, service it every 30k miles for longer transmission life.

I run Lubegard Red in all my trans and when I do a drain and fill I add back the 1oz/qt. It has been said on here that Lubegard Red is fine at even double the amount in a problematic situation. I have done just the rates stated above but wouldn't sweat if it was over that.

We're talking about 10R80's here. About 50 generations newer than a GM 4 speed.

Sure why not. Stuff is pretty well proven and I don't think you can really over-dose it. Or just run Valvoline Maxlife.

The Dynamic Coefficient of Friction Mu(v) hasn't changed from Dexron III to Dexron VI.

What has changed is: 1) the viscosity has been reduced from Dexron III to Dexron VI to the newer ULV fluids, 2) new friction modification chemistry has been introduced, but the Mu(v) is still the same for the Dexron series.

At this time, the only highly FM modified ATF is the Chrysler ATF+4.

Lets say I use the Lubegard ATF, does this mean I dont need the additive at all ?

I believe they use the additive in there line of atf's, so it should not need it.
