Quick Answer: Does Shifting An Automatic Hurt The Transmission?

Can I shift my automatic transmission from D to 3 2 or 1 without stopping the car?

How fast can you drive an automatic transmission in 2nd gear?

Back in the early days of automatic transmissions, when they had only 3 gears and no overdrive, you could of course do 90 or 100 MPH, maybe more in 3rd gear, so 2nd gear should be able to at least half of that. In my 2007 Toyota RAV4 the owner’s manual shows maximum recommended speed for 2nd gear is 74 MPH.

Can a clogged transmission filter cause shifting problems?

When the fluid level is low, it can lead to shifting problems. As well, transmission fluid that has become oxidized (burnt) or dirty can also create shifting problems. Next, if the transmission filter is clogged that can also lead to difficult, uneven shifts – but a fluid and filter change should correct this.

Why do automatic cars have 1 2 3 gears?

In order to keep engine revs and fuel consumption low, the gearbox will shift into highest gear as soon as possible. If you switch the gearbox lever to position 3, this limits the choice of gears, so the gearbox can only use gear 1 to 3.

What causes delayed shifting in an automatic transmission?

Delayed shifting is often caused by valves sticking the valve body, which prevents shifts from happening when they should. On newer cars, which control shifts using a computer, the problem could lie in the shift solenoids that are used to trigger shifts.
