Keeping your car Up to Date, and running is what Daytona does
FREE SCAN DIAGNOSE
Our first step in our full 21 point check is a diagnosis to check for codes. You do this in the same way you would check for engine codes. There are specific codes for automatic transmissions, but they are specific to the manufacturer. This means that we need to use our latest and special scanner.
Just about every late-model transmission is electronically controlled. This means that if you have an electrical failure, your transmission won't shift correctly.
Pulling the codes is a good way to find out if this is the case prior to going to the next step. If you have a shifting problem and you don't have any codes, check the fluid level and condition and we will move to a pressure check.
FREE PRESSURE CHECK
The first thing is to be able to differentiate between an automatic transmission problem and an engine performance problem, One of the easiest ways to find out if it's an engine performance issue or an automatic transmission problem is to do a power braking test.
In this test, we put the vehicle in drive or reverse, set the parking brake, hold the foot on the vehicle brake, and floor the gas pedal. The RPMs should top out somewhere in the 1500 to 3500 RPM range and hold there. If it's an engine performance problem, it will likely show up here, as you are putting the engine under an extreme load. You don't want to do the test for too long for that very reason, as you could overheat the engine. You're just performing a check here, you're not trying to blow up your engine.
moving up to this step we are checking the desired pressure inside of your transmission, if it showing below we will require a pan inspection.
TRANSMISSION PAN INSPECTION
The base of the oil pan can be an indicator of what's going on inside of the transmission.
There are different types of debris commonly found in transmission oil pans.
Brass shavings: If gold colored flakes are found in the bottom of the oil pan suspect wore thrust washers and bushings. These parts are often made of brass and wear as mileage accumulates.
Metal shavings: If metal colored shavings are found in the bottom of the pan suspect chipped or worn gearset teeth. This can also be caused by worn parts like washers, bushings, and springs used to assemble the transmission. Sometimes a piece of casting or slag can be found upon the first inspection of a new transmission.
Black pieces: If pieces of black debris are found in the bottom of the pan suspect wore clutch and band friction material. It's normal to find fine particles, especially around the magnet. Its job is to attract metal particles circulating in the transmission fluid.
if none of this is showing inside of your transmission we will treat your transmission as a preventative maintenance and we will address the problem to a potential solenoid issue, torque converter or valve body.
