What RPM to upshift at?
about 3,000 RPMs
Generally, you’ll want to upshift when the tachometer hits about 3,000 RPMs. It will be different for every car, but it’s a good rule of thumb. If you shift too soon, you’ll feel the car shudder, and you’ll need to downshift to keep it from stalling.
How to tell if transmission is slipping?
If your transmission is slipping, be aware of the signs.
- Engine revs or chugs.
- Slow, weak or delayed acceleration.
- Difficulty shifting gears or hard shifting.
- Grinding, whining or other strange noises.
- Won’t go in reverse.
- Burned or strange smells.
- Check engine light.
What does it mean when your transmission is not shifting?
Q: transmission not shifting and the rpm’s keep climbing up. the transmission is not shifting properly, replaced both input and output speed sensors, but the rpms seem to be climbing high and the transmission does not seem to be shifting, gets up to speed fine, but the rpms just keep climbing on it… My car has 200000 miles.
Can a bad transmission shift solenoid cause hard shifting?
You may also have intermittent problems with the transmission shift solenoid, which will cause shifting problems. This can cause hard shifting or shiftings at too low or too high RPM, for example.
Is there a point in trying to change gears fast?
There’s no point in trying to change gears as fast as possible (even on a race track, the gain is minimal) but it’s very hard on the box. I second Timo’s assessment: it’s likely that the synchromesh gear (AKA synchro) is worn badly enough that it’s not able to do it’s standard rev matching for you.
Can a car go over second gear at low speeds?
It occasionally shifts into third gear within a mile of driving, but after that, it cannot shift over second gear. Also, when this issue starts happening, even though I am driving at very low speeds from 25-35 mph, the RPM increases to around 2800. When I attempt to accelerate, it cannot go over second gear.
