I have a 2012 Silverado on order and should be here by the end of March. I have been reading everything on LGR and wondered if I should add it to the truck when it is delivered. Truck will be towing a 6000lb camper to Indy at the end of May.

Prime reason for LGR would be to have cooler transmission temps.
 
My personal opinion would be no, not on a brand new vehicle. LGR made an impact on DEX III ATF, but dex 6 is at least a semi-syn, maybe full, and won't benefit as much. At least in my mind.

Best thing to do is while towing keep an eye on the transmission temps, and take it easy on hills. If you don't like the temps your seeing, maybe consider adding an aftermarket ATF cooler.

Driving habits while towing will make the biggest difference in temps, without changing anything about the vehicle.


Hope you enjoy the truck though!! Be sure to post pics when it arrives!

Best of luck

It is a 1500 with 6L90 and 3.73 gears. Has the factory external cooler. I have one hill that my last truck 4L60 with 4.10 temp would just get to 230 when I got to the top.
 
LGR or any premium ATF will not lower the temps of the transmission. A premium transmission ATF will however be able to handle the higher temps without a problem. As another poster mentioned, DEX IV is pretty close to being a premium ATF.

Donald you really hate this product don't you?. But you never seem to back up your statements with facts or data.
Have you ever even tried it, done a simple scan tool test?

Fact. LG is patented, it is approved by major OEM's and TSB's have been issued by OEM's (the latest being Subaru) recommending the use of LG to correct non mechanical issues in their transmissions.
LG claims up to 40f reduction in temp, no one have ever accused them of making false claims. On the contrary OEM's have actually embraced the product to the point that some have it repackaged and have gave it an OEM part#.

Snake oil is snake oil but this is not one of them, this product works and works well even as a preventative in a new or rebuilt unit.

+1 I'd add it w/o hesitation! Just be sure not to over fill the unit.

Not to pick on you, but if he can afford a brand new truck, and a camper, a trans cooler shouldn't be out of the budget.

When LUBEGARD LXE®(Liquid Wax Ester)Technology is present in the oil, its molecules are adsorbed onto the internal metal surfaces soaking up the heat and transferring it to the bulk oil from the metal surfaces. The oil and LXE molecules containing the heat are then dispersed to the external metal housing where it is dissipated to the atmosphere (surroundings). Other competing additives can actually trap in excess heat in critical functional areas - likely resulting in failures.


A bit of scripting license has been employed here to the subject of thermodynamics:

Heat is transferred by ALL fluids, whether mineral or synthetic. With synthetic fluids, there is a very minute increase of heat transfer over mineral oils.

Somewhere on this site I calculated the very slight increase in heat transfer by synthetic oils verses mineral oils.

You have to remember that heat is transferred by many methods, but mostly by convection and conduction. If heat is not transfrred out of liquid molecule, it goes through a phase change to a property called a "gas." So you cannot "trap" heat without a temperature increase in the substance and the liquid changing to a gas, called "volatization."

LG has extra anti-oxidants, a small amount of AW additives, and the esters in a base oil.

I still don't see a need for it in vehicles using the newer low viscosity ATF's.
 
^I agree with this as well. I feel as though neglected, re-built, or perhaps transmissions with some know issues/symptoms early in life this is a nice way to curb things. On very well built units now a days using Full Synthetic ATF and getting regular service, sure there isn't a need outright. At that point, just like a synthetic engine oil you 'could' chose overkill and ad a product like Lubegard Red. Sorta like adding MoS2 into a synthetic oil like several do.

It's the nerd in us all. lol.

For me, the question of when it becomes a 'potential' issue or simply 'not recommended' is of more importance to discuss at this point, if even possible to broach that subject. Aside from those that simply ask if they could use it in their specific app, are there certain transmissions this would not go well with?

CVT and Ford Type F ATF are already stated outright.
 
Other than the AT units such as CVT's or Ford Type F or racing transmissions that use type F fluids, no.

I have not heard of any transmission failures due to the use of LG Red, but does it really help the modern low viscosity ATF formulations, I don't think so.
 
Latest thinking re my issue of kicking out of reverse into neutral on a cold morning on first start of the day. This is a REBUILT GM based transmission in my BMW 525i. Note the recomendation to help resolve the issue.

The rebuilder stated that as the valve body parts are new and one or more components appear to be sticking when temperatures drop near freezing. The parts usually "work loose" with mileage. For example it was perfect today with a low temp in the 50s.
However, before they replace components they want my BMW shop to use Lubguard Red transmission additive to help free up the sticking component. I do not see a problem with this approach as there is no cost to me. From all accounts this is an excellent product. See link below.
