Question about 2001 Hyundai Sonata

1 Answer

My car does not know when to shift gears sometimes ... high revs but still in first ... shift to second at 40 ...squeals the tires . ..has been suggested the speed sensor is no good ... however it may also be that the transmission ECM is no good yet, you can not tell this unless you install a new speed sensor ... Is this a correct approach ... the car has 130 k on it ...

Try to hook it up to a computer first before you go and buy a sensor so that you do not waste money that doesn't have to be spent. if it is the speed sensor it should trip a code on the computer

The car starts right up perfect its just when you start going it shifts from first well, then in second and third gears it revs really high before shifting tothe next gear, it doesnt seem to shift well, it...


Without getting into transmission diagnostics that would require special tools, you can check the transmission fluid level. You could also drain and replace the trans fluid to see if this solves the problem. Changing the fluid is considered regular maintence, and will not hurt a thing. The trans will benifit from fresh fluids in the long run also.

My car is reving up when I down shift to slow the car down in 4 wd.


As it should. Lower gear means higher engine revs.

Warning - downshift at too high a speed will cause damage to your engine and transmission.

Why are you dong this anyway? Saving the brakes? Pads are about $30.00 and should last 30 - 40 thousand miles. Downshifting puts unnecessary strain on your entire vehicle, even though it might be fun. It also increases fuel consumption and is hard on the tires.

Cannot accelerate past 40 mph


Hi,
Does it rev ok? If your motor revs high but still doesn't go fast, you could be having a transmission issue, where it's not shifting into high gear... I'm assuming it's an automatic.
I hope this gets you on track... Good luck.
