ATC Plus

I've used several of their products over the years (used to be an auto mechanic) and this one worked wonders. At least 75% reduction in torque converter shudder (after I tried everything else :( ). Expensive but well worth it!

Changed my transmission fluid at 92k miles with this additive per mechanic's recommendation, not overly optimistic about fixing the stuttering on my 2016 Odyssey. Since then the stuttering has completely stopped and she drives as smooth as the day we picked her up with 45k miles. Whether I needed the additive with new fluid, I'll never know for sure, but I figured what's another $18 on top of the $50 for the Honda fluid. I highly recommend trying this product before taking your ride to the dealership.

I have a 1997 Honda Accord, I used only about half of the can. Did a drain and fill with this and vavoline hm trans oil. I had a issue before where it wouldn't down shift correctly and threw a code for the shift solenoid. Thought I would try this because I worked at a oil change place that sold these and I did it to many cars and my own vehicles and always saw a difference. After a little of working the new fluid in it began to work much better. The more I dive it the better it seems to get :) after months it's still doing good. Would recommend BG they are amazing for additives. **Don't do any cleaner for high mileage vehicles. It could cause miss shifts. This product is okay for high mileage though. Also if you have a smaller motor 4-cylinder don't add all of it.

Was getting some delayed shifts and bumps when first warming up my 2013 Camry. Its a knock around car I bought used with 185k mi. I knew the transmission fluid had never been touch because the ATF was black as my Labrador. I did a drain and fill with Toyota WS ATF and that seemed to make it worse. Thought I was screwed and figure what the hell have it "flushed" (completely drained from the trans cooler hose) and added a can of BG ATF. Shifts like new now, no issues at all. Hoping it makes it to 300k and then I certainly got my 6k worth of car. Thank BG, going to look at your other oil products. *** Seen some of the negative reviews... Its says right on the back not for CVT transmissions or Ford type F, do 5 minutes of research before changing / adding anything to your new or old transmission.

BG ATC is a good product, the cans was in perfect condition. We'll pack. Will buy more

I will update when I've seen it's use over time some more. Shifting is now smoother on my 95 second gen 4runner, sometimes it's still not wanting to pull off right away, but I feel like it's still just getting the seals loosened up. I was able to do 70 again on the highway, and there was less rumble under the foot pedal... What felt like grinding almost.

I had this in 14 days so far and works awesome. My tranny was kicking really bad when shifting where it would kick me from seat a little. And belts were wining like crazy. But now silent I only hear any noise if VERY long trips but nowhere as bad as it was. This can has saved my tranny I'm not ready to do the job of replacing yet. Make sure you read the label though it says 100 miles before seeing a difference and it is true. If not a little more but so worth it. I have to admit I was doughtful especially the first week but I love it. And yes if you need to know I did NOT do a flush. But I did a tranny filter and put new fluid in. I so recommend this. My uncle is a mechanic and suggested this. I agree 😁😁😁😁😁😁😁😁😁😁

The best additive on market. Never settle for anything less. It does what it says
