How Can I Be Sure Its The Transmission?
Last Updated on Friday, 13 November 2009 16:41 Thursday, 12 November 2009 14:53
There are many symptoms of a failing transmission that are also shared symptoms of other things that can be wrong with your vehicle, other than your transmission, such as transfer case or differential or even a Engine Miss or slipping clutch. The best way to know for sure is to take your vehicle into your ATRA Certified transmission specialist.
Here's why: Wouldn't it be a perfect world if your vehicle could actually " talk " to you? Tell you when it isn't feeling right, and then tell you what to do to fix it?When you get a common sickness, ... you can go to the doctor ( often knowing your diagnosis before you even arrive at his office), tell him your symptoms, And the Doctor simply makes you better.
So now your car isn't driving right.... You're sure it is the transmission..... You try to pass another vehicle and all of a sudden it feels like someone slammed on your brakes... or your car is stalling at every stop light..... and when driving at faster speeds you feel a "shudder." These problems commonly accused on the transmission, have many times been due to something else.
We know that our vehicles can't "really" talk to us ...at least not yet anyways....... But we can give thanks to Automotive Engineers and their idea to put computers inside all late model vehicles. Our cars use one computer and/or multiple computers which share information with each other to control the engine and in many cases the Transmission.
The computer inside your vehicle uses sensors to keep track of important information that your vehicle gives out. Like how fast you're going, throttle position, the input speed of your transmission, and the different switch positions. We drive many different speeds, our acceleration increases and decreases as we drive on and off highways, and as we're passing other drivers, and even when we're coasting or slowing down with traffic to an idle.
The computer in your vehicle knows how you're driving because it uses the sensors throughout the vehicle to monitor the cars engine and transmission performance. So as we drive on and off freeways, demanding constant changes in speeds, using our everyday maneuvers like passing, slowing down as we approach a stop, and even when we're at idle..... the computer acknowledges this from monitoring certain sensors. And then to improve fuel economy, the computer can engage a clutch inside the torque converter.
The problems you had on the freeway, or at the light, could be a number of things. Without special equipment and an experienced Transmission Shop Service Professional, you can't tell if a "shudder" or " pulling" is caused by the torque converter, a slipping transmission, limited slip differential, a dirty fuel injector, or maybe a weak spark. It could be a number of things.
Alliance Transmissions would like to thank Mike over at CapitalTransmission.com for this great answer.
