Lubegard63010 Platinum Automatic Transmission Fluid Protectant, 10 oz.

I have a 2007 Hyundai Santa Fe GLS 4-speed. I've noticed a big difference in shift quality and gear hunting. I can't say if this will work for your particular application. I'm no professional but I don't think it could hurt. Certainly happy with it I will be adding it with every drain and fill. I've done a little reading and I know they used to use whale oil in transmissions before that became illegal. Apparently this stuff mimics the effects of oil which is very good for the transmission. Everything is a lot smoother. Car seems happier overall. Anyway that is my honest review. Good luck with whatever you're working on.

Seeing as GM is the new leading name in garbage transmission designs, I can comfortably say this is a game changer. I have personally used this product in dozens of 8 speed transmissions and specifically I used it on my brothers personal vehicle. It resolved all shuddering almost instantly. I have been a long time Lubegard user, and I can proudly say this is a product I stand by!

I don't have any shifting issues. I was just looking for more performance and protection on a car with 170,00+ miles. After about 100 miles it smooths out the shifting. Whether you have a low or high mileage car it is good insurance. I use their oil additive and power steering additive as well. If you aren't having issues yet I would use this before using the red.It has a great additive package and will give you peace of mind on a high mileage car.

Works great. Cars shifting easier.

Good product so far, pour into truck and drove couple hundred miles. Definitely worth the money.

Been using during fluid changes with GM 14-18 pickup trucks. 6 Speed and 8 Speed. If the transmission doesn't have any major physical wear, this helps smooth out the shifting and shuddering. Using with Mobil LV Blue.

My car is 10+ years old, and became more sluggish by the day since 7 years ago. No mechanic could identify the cause. The AT recently started to jerk when shifting gear and often produce the sound and vibration you get when trying to close a door that is large than its frame. I was certain that a $3000+ AT rebuild cost is just hours away, and it won't be worth it for such an old car. After hours of research, it's clear that I need at least try to change my AT fluid. Just by luck, the cheapest place (it's not one of those quick lube big chains) is a family owned small lube place that uses only genuine Honda fluids, yet quoting half the cost of the chain lube places. I later read that genuine Honda fluids have additives not found in other brands. After the ATF drain and fill (not flush - do NOT flush if you already have AT problem), the sluggishness that started 7 years ago (which was when some mechanic put in generic ATF) was instantly gone. Within a few hours, the jerky and banging shift improved by 70%, but not totally gone. Then I added around 4 oz of Lubegard, and started to look for improvement. But now I have a new problem, and it is "a very nice problem to have". I just can't notice any gear shift! The car goes from 0 to 65 mph, as if no shifting was done. But the car cannot logically go at 65 mph at 2000 rpm without somehow having shifted to 5th gear, and can't go up steep hill without having downshifted. It's just that the AT is now so quiet and smooth that it is just unreal, and I can't feel the shift points. Now that I have genuine honda ATF, and genuine honda motor oil, and I have just put in a bottle of techron, the car is now smoother and has more power than the day I first owned it. I have to change my foot pedal habit to make sure that the car does not accelerate too fast. I am writing this so that anyone else in my position would not despair before at least trying some cheap possible solutions. The total cost of my car's rebirth is $11 for the lubegard and $4 for the techron. The ATF and oil change are things that would have to be done anyways. Why not flush the AT? Try "flushing" an ice cube with sharp edges down your throat, and you would understand. Compare that with waiting till the ice melt bit by bit, and becomes fluid, and flow natural down. Instead of flushing the AT, do a standard drain and fill with honda fluid (or whatever premium best fluid you like, not generic cheap fluid), then drive the car for a few weeks, and do a standard drain and fill again. Metal bits that cause problem become ground up gradually and naturally, and flow away into the filter. Otherwise, you are basically trying to flush a wood log through a pipe, and get to find which one breaks first. To sum it up, premium ATF + motor oil + LG + techron gave me a new car. Hope that works for other people. Good luck!

Worked for me!!! I had transmission serviced, shudder disappeared within 50 miles.
