Lubegard 63016 Platinum Universal ATF Protectant, 15 oz.

I never thought I would put an additive in a ZF transmission, however I decided to take a chance with this one as my auto was starting to feel a bit tired. I am very glad I did the auto is now running better than ever, enhanced shifting patterns, staying in correct gear for longer, cooler and absolutely butter smooth changes. It took a good hour of driving for the electronics to relearn the new friction properties and then presto absolutely perfect. Don't be scared this product is excellent and is also backed up with OEM recommendations and approvals.

Works well

Always been a fan of Lubegurd!! First time trying this product. I always been a fan of Shudder Fix , but my issue was much greater. I own a Ford Crown Victoria, I had the vehicle Transmission serviced, I thought they were gonna use Mercon V Transmission fluid, However they use a multipurpose ATF. After that I started having overdrive problems. So at first I use the combination instant shutter fix along with the synthetic ATF protectant ( Red bottle ). So using a pump through the dipstick transmission dipstick I pumped out about 2 1/2 quarts of transmission fluid replaced it with Mercon V and added Lubegard’s synthetic ATF protectant with instant shutter fix. Usually you have to give it time about 300 miles of driving for additives to blend in and do their work. This still did not solve my problem. The issue after researching and reading, was I needed to convert the multipurpose ATF into Mercon V. I needed to improve shift quality,and eliminate Torque converter shutter. I seen a bulletin that general motor uses 2 ounces per quart to eliminate something like this so I read up on lube guard platinum. I decided to give it a try before having to drain the whole transmission and replace 15 quarts of Mercon V. So again I drained 2 1/2 quarts through the dipstick, Replaced it with fresh Mercon V, I took into account 1 ounce per quart of Lube Gard Platinum ( Silver bottle) plus Lube Gard ( Green Bottle), And gave it a test run. It took a couple weeks to kick in I don’t drive that much. But after around 300 miles my problem went away. I do want to add that I usually do transmission fluid and filter service every 30,000 miles. And it was my mistake that I was trying to save a buck and went with a tire shop to do my transmission service rather than a Ford dealer which would’ve used the recommended OEM transmission fluid and avoid all this problem together. I hope this helps.

I always add this product after fluid change. Good stuff.

I read about this product through an automotive forum as many were touting great results with it. I have a 2006 Honda Odyssey with 260,000 miles on it. Transmission fluid was flushed and changed at a local shop at about 130,000. Started noticing transmission shifting harder almost immediately after the flush. Transmissions are known to be weak on these cars and I was starting to have issues with hard shifting and clunking in my transmission after the flush. It got progressively worse over time. We were seriously afraid to drive out of town in the car. Rebuild on the transmission was quoted at $3500. I had tried a couple of different brands of transmission additives over the past with little results. Decided to do a drain and refill on my Odyssey transmission and add the recommended 1oz of Lubegard per quart on the refill as recommended on the automotive forum. Transmission fluid was very dark and dirty. Drove the vehicle a couple of weeks allowing the Lubegard to work noticing some positive changes. Then did 2 more drain and fills to get all the old tranny fluid out of the torque converter as well. Each time adding the 1oz lubegard to each quart put back in the tranny. Be careful of over-shocking the transmission by adding the whole bottle of lubegard at one time. Only add the 1 oz per quart of transmission fluid put back in the transmission at the time of fluid change. I ended up doing 4 drain and fills on my transmission to get all the old transmission fluid out and adding the Lubegard with each change. Drives like a completely different car now. Be cautious flushing your transmission out if you are having transmission issues already. Drain and fill is much better since you are only replacing about 1/3 of your transmission fluid at a time and it slowly cleans without a massive shock to the transmission system. I have since used this on my 2 other vehicles and am very impressed with the product.
