Why does my RPM drop when I put it in drive?
The engine RPM drop when changing gears is often caused by a failed throttle position sensor (TPS). When in use, the cone of the TPS accumulates soot that prevents the correct rod movement. If a TPS works abnormally, the air-fuel mixture will not meet the requirements.
Why do automatic cars accelerate slower?

It’s because automatic shifts between gears on lover rpm’s and on manual you can push it to the limit, so basically its like you are on bike and shift in higher gear just after start, it is much harder to accelerate and so it’s slower.

What causes engine rpm to drop when upshifting?
A common issue that leads to the engine RPM drop when upshifting is the clogging of the fuel pump filter. If cleaning the strainer didn’t help to eliminate the RPM drop, replace the fuel pump. If FMU is in a faulty condition, the engine RPM drop when changing gears is caused by mainly the same reasons as with a failed fuel pump.
When is it a good idea to shift into drive?
