Lubegard question

[otis24]

Recently, I took my 1991 Chevrolet K1500 to a reputable tranny shop to get the tranny flushed. The tranny shifts fine, but the fluid was slightly brown. When I went to pick up the vehicle, they only did a fluid exchange and filter replacement (about half the cost). They stated that they did not want to cause issues with the tranny since the fluid was brown.

Will I receive any added benefits by adding Lubegard Red? I know its a good product. Its not too expensive and if it will help prevent issues down the road, it may be worth the investment.

LG's a great product but like with any additive, only use it if there's a specific issue you're trying to address.

I would make sure they replaced the fluid with a good DexIIIG or DexVI equivalent replacement.

What fluid did they use and what did they write on the ticket?

Best thing is to have a drain installed in the pan on these old trannies and just drain and refill the pan every 15 to 20k miles with a good fluid. You will eventually get the old fluid out that way.

My 1986 200R4 was done like this. I use Valvoline Maxlife. Tranny shifts great.

According to my GM shop manual, brownish transmission fluid is normal, and the manual I have is from 1992. My fluid was brownish in color like that too in a GM turbo-hydramatic T340(125C). I changed filter and fluid, and I did put in eight ounces of LubeGard Red. Transmission shifts great, and I feel confident that my transmission is running cooler now with less wear, and that the fluid will last longer with the addition of LubeGard Red.
