transmission

At Hyannis Transmission II in Hyannis, we’re familiar with the many over the counter remedies that promise to cure your car, truck, or SUV of all its transmission woes. But, do any of them actually work, and are they even safe for your transmission?

First, you should be cautious about pouring anything into your transmission that isn’t specifically recommended by your manufacturer – typically that excludes everything besides factory mandated transmission fluid. While there is, in some instances, warrant for certain additives, they really shouldn’t be utilized without an opinion from an expert. The old shade tree mechanic down the road who swears by funneling in half a quart of diesel might have been onto something in the 1970s, but especially in modern cars, you want to be extra careful. After all, your transmission is the most expensive and most complicated component of your vehicle.

Second, it should be known that most additives, particularly ones that relate to the transmission, are barely any more reputable than the snake oil scams of covered wagon con artists. Best case, they do nothing, and worst case, you end up with a voided warranty and even worse transmission issues. By and large, transmission issues must be professionally corrected…even on the off chance an additive is able to help, you’re simply prolonging the inevitable and increasing the chance of further damage.

If your transmission is acting up, don’t start pouring mysterious fix-all liquids down the dipstick tube. Our professionals have your back.
