BG ATC Plus by BG Automatic Transmission Fluid, 11 fl oz, 0.7 lbs, Maintain Automatic Transmissions, Prevent Corrosion

Great product

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.

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.

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.
