Can a transmission keep your car from starting?
Certainly. Automatic and manual transmissions for decades have had what is called a neutral safety switch, which disables the capability of the car to start while in gear. On older transmissions these were mechanical, and as such could wear and break… disconnecting the vehicles starting circuit even in park or neutral.
How does a torque converter work in a car?
A torque converter uses power from the engine in an automatic transmission to change gears. Think of it as the clutch in a manual transmission. Each time you move between gears, you have to press down and slowly release the clutch. The blade assembly inside of a torque converter controls the flow of transmission fluid.
Which is worse a bad torque converter or bad transmission?
When diagnosing driveline problems, one of the bigger challenges can be diagnosing a bad torque converter versus a bad transmission. The symptoms are often quite similar. Often people think that their transmission is going out, because the symptoms of a bad tour converter are so similar to the symptoms of a bad transmission.
Why does my torque converter stall while driving?
So you’ll be driving down the highway and suddenly the car will start to vibrate and if you keep driving faster that vibration will stop. High Stall Speed – A torque converter’s stall speed is the engine rpm needed for it to engage the engine. This is often one of the symptoms of low transmission fluid.
What to do if your torque converter is slipping?
If you are experiencing a slipping torque converter and you have replaced the transmission fluid and filter and even done a transmission flush to it, it’s time to remove the transmission from the engine and inspect the seals on the axle into the transmission. Here is a video of how to replace the seals inside a transmission.
Why is my torque converter not working properly?
The RPM (revolutions per minute) measured once the car’s engine maxes out is its stall speed. If the stall speed measured is lower than what is specified for your torque converter, then it may be the beginning of its end. On the other hand, if the stall speed is higher than expected, it may be because the transmission is beginning to slip.
When do you need a high stall torque converter?
Many people will tend to over cam and carburet their cars, and those people under stall which sucks. If you are needed a 3000 RPM stall, then they will get around 2000 RPM, which doesn’t get it off that starting line. You need to remember, 80% of the race is going to be the first 100ft.
How does a torque converter work with an automatic transmission?
With an automatic transmission the torque converter does the job that the clutch would do in a manual transmission. The main benefit to a torque converter is that the engine will keep running at a standstill.
Why do you need a sound torque converter?
A sound torque converter handles how much fluid is passed on to the transmission area and allows your engine to work optimally. Also, watch the above video for other Torque Converter Noise to guide you more.
