ATC Plus

Best additive for automatic transmissions hands down! Always ask to include this with any automatic transmission flush or service, compatible with most all applications that I know of, check with VVT applications to be sure though.

All I can say about this product is buy it buy it buy it buy it I read and a previous review my transmission shifts like butter well I'm telling you I dropped two cans in my 2004 F250 it had a shuttering torque converter and I noticed a difference immediately the more I drove it the better it shifted no more Shutters no more stalls. It's amazing. I recommend anyone who has a problem with their transmission before taking it to a mechanic to buy two cans and drop it straight in on top of your existing transmission fluid that's all you do saved me thousands.

2021 Silverado 2500HD 4x4 l8t 6-speed. Trans started shifting funny. I started watching my trans temp. Running 212F-225F unladen. I realized there is a problem. The solution was to replace factory transmission thermostat with updated 158F/70C thermostat. Did a fluid/filter change(dropped pan), and still shifted unusual. Themp now running 147F-160F unladen. Pulled 1qt from trans check bolt with truck on angle cold. Mixed 11ox BG ATC Plus with enough new fluid to make 1qt. Shook well, and pumped in fill port. Shifts like a dream.

Put in a 2009 Outback 3.0R with a 5EAT transmission. After changing the fluid 3 times, I added this stuff. It definitely helped make the transmission feel smoother. I wasn’t having any slipping or shifting issues, but sometimes the transmission felt a little lazy. It helps a lot. This isn’t going to fix your transmission if you are slipping or missing gear changes. It’s not a transmission repair. It helps an old transmission shift better by softening up hardened seals, increasing viscosity which helps worn valve bodies direct fluid pressure faster when the fluid is hot, and it replenishes friction modifiers as well as detergents for when your transmission still has old fluid mixed in with new fluid.

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.

Great product

Recently had a transmission service done on a vehicle with a hundred thousand miles. After about an hour I noticed the vehicle would shift harder through the gears. No I added this product to help ease the shifting between the gears. It did help but the transmission still was shifting hard between gears.it won't fix mechanical problems. Butt does help with extending the life of.your working unit.

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.

Amazing product makes the gear very smooth
