It is the cluster I had to have my replaced at 40,000. miles . I think they got ahold of some bad ones.
Small stepper motor that controls speedometer needle position has a cracked gear in it.
Yes it is true about the steeper motors, Each gauge has a stepper motor in the back
I had the same problem in my car. I found a website where I had my cluster rebuild for $140. That's a lot cheaper than the $750 that the dealer wanted to replace the speedometer. Here is the address incase you wanna check it out: www.speedometergaugerepair.com
How tofix dish light for impala
Due to the nature of the problem 'irregular speedometer' it has to be repaired by a licensed mechanic.
Replace your speedometer sensor. I just had mine replaced in my '04 Impala. The sensor tells the tranny when to shift. It's located right in front of the transmission.
If the speedometer and abs light are not working then you have a speed sensor problem. If the speedometer or odometer are not working then you will need to take it to the dealership and have them send it off for repair.
To fix the inoperative speedometer you will need to replace the speed sensor. It is located on the side of transmission and has 2 wires coming out of it.
First remove item from dash then remove speedometer from cluster, and then look for seam where speedometer comes a part and then disassemble from front to back keeping all items in order
the cap should have a measuring tab on it ===hot and cold readings
What year is your Impala? 2001
I have an 05 impala and had problems with the speedometer and fuel gauge. The only way to fix it was to replace the whole instrument cluster. Pretty easy to do, only took about 45 minutes.
Stepper motor for speedometer has a broken gear in it, causing unpredictable operation. If the odometer is still working, then the speed sensor is OK. Instrument cluster needs repair.
NO. It is illegal, can cause low power and poor fuel economy as the computer tries to adjust for the improper readings from the O2 sensors.
The factory shop manuals have the wiring diagrams for everything in the 64 Impala. Carl King http://www.classiccarauto.com The only "wiring" to a trans in a 64 impala would be the neutral safety switch and the back up lights. it's not an electronic solenoid type transmission and the speedometer is a mechanical drive.
