How does the first stage of an automatic transmission work?
It acts like two planetary gearsets connected to each other with a common planet carrier. The first stage of the planet carrier actually uses the larger sun gear as the ring gear. So the first stage consists of the sun (the smaller sun gear), the planet carrier, and the ring (the larger sun gear).
Why does my transmission go into a different gear?
Transmission goes into different gear than selected There could potentially be a mismatch between the gear selector lever and the sensor input signal. This would cause the transmission to be in a different gear (controlled by the PCM) than the one selected by the driver using the shift lever.
What’s the gear ratio for a manual transmission car?
If you wanted a top speed of 80 mph, then the gear ratio would be similar to third gear in most manual transmission cars. You’ve probably never tried driving a manual transmission car using only third gear.
Where is the transmission located in a rear wheel drive car?

What’s the difference between L, 2, D3 in automatic transmission?
As the name suggests, the D3 (or sometimes just 3) mode will only utilize the first 3 gear ratios of your car, or in some, locks it on the 3rd gear only. Just like the 2 and L, it will shift at a higher gear if the maximum RPM has been reached.
What are the gears in an automatic transmission?
In a car with an automatic transmission, we are normally greeted by the acronym PRNDL, or in some cases (older cars) PRND21. I know that the L, 1, or 2 will cause the transmission to stay in a (L)ow gear and not upshift, but I’ve heard various explanations of what the low gears are for.
What do the letters mean on the gear selector?
A: That’s what’s known in the automotive world as the “prindle,” the pronunciation that engineers bestowed on the transmission gear selector because it commonly contained the letters PRNDL for Park, Reverse, Neutral, Drive and Low.
