Review on 🛢️ Lubegard 61910 Highly Friction Modified Automatic Transmission Fluid (ATF) Supplement, 10 oz. by Ken Barnett

Truck shift problem when cold only. The previous owner did not change the fluid. So I decided to change the fluid. It helped a little, but there was still a switching lag. I have used this product in the past and have never been disappointed. As soon as I filled it up and took a test drive, I immediately felt the difference. This product will definitely clean and break down any deposits that have built up on the transmission valve body/shift solenoid. Just make sure you choose the right greaseproof additive for your make and model.
