How To Diagnose Your Automatic Transmission Problem

For a person who isn’t car-savvy, the transmission is undoubtedly the most difficult to understand. There are so many different parts to it, it feels impossible to decipher what may be wrong with it when it’s not working properly. Here are some ways in which you can try to find out what exactly the problem is with your transmission.

There are two groups of problems that are caused by the exact same faults in your transmission, so whichever your car happens to be doing, the following applies.

It is extremely important to check your transmission fluid at least twice a year. Not only can a low fluid level cause your car to shift poorly, it can lead to some very serious damage and an incredibly costly repair, something we are trying to mitigate here. If your car seems to be losing an excessive amount of fluid, you most likely have some type of leak.

Checking for a leak isn’t as bad as you think it is. Understand that the transmission is a closed system, so there are a limited amount of places that your car can leak from. Unless your transmission fluid has been changed to a neutral fluid, your car should have red transmission fluid.

Here are the several places that you need to check for a potential leak: At the filler tube base, at the drain hole under the transmission, between the transmission and the engine, at the selector shaft, under the speed sensor mounting point, or on the radiator. The selector shaft is the rod that connects the gear shift to the transmission. The speed sensor mounting point can either be a cable screwed into your transmission machine, or an actual sensor that is just bolted in. If your car has a transmission cooler, it is likely that the transmission fluid will leak into the radiator fluid. These two fluids don’t particularly mix well, so you’ll probably find it sitting there.

Another common problem that people have is that their filter is clogged. If you haven’t replaced your filter in a while, be sure to do this, as this is a very common problem that people don’t troubleshoot before the go spend a fortune at the car mechanic.

Unfortunately, most transmission problems can’t be done by yourself, as there are so many specialized tools to fix so many different issues. Do not worry though, as Grisham’s Transmission will fix whatever problem you are having for an affordable price. Call today at 615-226-2879.
