Impossible to make an accurate diagnosis without knowing the YEAR, MAKE, and MODEL of your vehicle. Generally, however, the problem you are describing sounds like a problem with the SPEED SENSOR.

Replace the speed sensor on the trans that will cause exactly what you describe is happening.

Hi,

Here is some possible reasons why your transmission is having those problems .

* The gear shift linkage is binding
* There is an internal problem in the transmission
* The throttle cable is broken or disconnected
* The vacuum modulator on the transmission is faulty or the vacuum line is damaged
* The electronic transmission control circuit may be faulty

What is the cause of the Toyota Gaia dragging in gear change, while dragging the speedometer does not read, once the gear shifts the speedometer starts to read, everything then becomes normal?

no car stated (Gaia what? er Toyota )
2.0Liter told later
no transmission type, AUTO IT IS. NOT STICKSHIFT.

I guess dragging means delayed shift in the automatic>?

why not ask your autoshop this,.>?>?> as 99% do.

if any automatic fails to up shift the speed is low
speed low cause the speedometer to read low.
not upshifting can be cause by 2 things, weak engine or bad transmission.
you will never learn or discover why only your shop will. BUT I did answer below. and can expand each line by 100 fold if need be.
and more if the year car was told or what transmission model is there, some cars had 2 choice or more back then.

Why when i put in drive and go it goes into 1 or2 or drive by it self while driving

It always starts out in first, it's a 3 speed automatic, that's what automatics do. they start out in first and at about 15-20 miles per hour , they shift to second gear, and when the speed is about 35-45 MPH, the transmission automatically shifts into third gear, or Drive.

Bigger automatics have 4 or more speeds. Till recently, 4 speeds were the norm, and fourth gear was often dubbed Overdrive, as it allowed the engine to run slower in 4th gear, than it had to maintain speed in 3rd gear, drive. It's good, it increases your mileage per gallon of gas, so you save that way, but like all things more complicated, they cost more to fix when something goes wrong.

2000 cirrus want change gears goes in drive and reverse inside on the dash where it tells you what gear you in all has squares around them speedometer doesn't work

Sounds like a speed sensor, I will look into that, but if the speedometer isn't working, its either cable, or electronic. Being a 2000, I'm guessing electronic. Chrysler have a lot of electronics on the transmission, as they are electronic themselves. I had an alternator go bad and my battery died, and the car wouldn't shift, it actually down shifted while driving. Have your battery and alternator checked first, then sensors. Like shift silinoid, speed sensor etc.

I was drive the car running and shifting goog, then the speedometer went dead and transmission started sliping bad. Then the speedometer started working and it quit slipping for about a quarter mile t

Your speed sensor is giving out I believe. The transmission is fine, I'm very sure of it. So in short: It's electrical!

FYI: When the speed sensor signal is not reaching the computer, it doesn't know if/when to shift gears, or what gear to even be in. That's my basic summary of why this happens. There could be more to it than I know considering it's a newer car... but I think I'm right about it being a speed sensor.
