What is measured by a car speedometer?
Older cars have a cable, which is turned by a gear at the rear of the transmission, and this operates a mechanical speedometer. Modern cars have an electronic sensor in the gearbox which is linked by wire to an electronic speedometer.
Will changing gear ratio change speedometer?
Yes. The speedometer reads off the transmission tail shaft, and the speedometer is geared (in a mechanical system) or programmed (in an electronic system) accordingly.
Can Benz 1982 transmission 300d Speedometer mechanical - electrical?
I have an 82 300sd and the speedometer is electrical
What would cause a 1991 Mazda Protege to have a blinking hold light and a non-functional speedometer?
The speedometer cable (which runs from the transmission to the dashboard) has snapped. This is a two-piece cable, and the one-piece cable in later Proteges will not work. I had the transmission replaced, and the cable could never be fit in properly. This is a mechanical speedometer, so you would have to change the entire speedometer part of the instrument panel to use a magnetic/electronic speedometer.
What could make a speedometer not work in a 1995 jeep grand Cherokee?
I'm not 100% certain, but I believe that model year still uses a mechanical speedometer, in which case, it's likely either your speedometer cable or faulty gears in the speedometer itself. If it is electronic - which is possible, as again I'm not 100% certain that the 95 uses a mechanical speedometer - and the rest of your gauges are working, there'll be a speed sensor on the transmission with an electrical pigtail running to it... faulty sensors or faulty wiring are the probable causes.
Where is the speedometer gear located on a s1700 SCHOOL BUS?
If it's old enough to have a mechanical speedometer, it'll be in the speedometer itself. If it has an electronic speedometer, there is no speedometer gear - to recalibrate the speedometer to match something like, say, changing tire size would require changing the parameters in the engine ECM.
How do you know if your transmission is cable or electronic for a 1993 Ford Ranger?
If it's a stock transmission, the shift linkage is mechanical.
Why does the speedometer on your 1991 Toyota pickup 4 cylinder 2wd shake or flutter?
Back in 1991 I THINK that they still used a mechanical cable from the transmission to the speedometer. Only later did they change to electronic readout, but I'm not sure what year. It sounds like the speedo cable needs to be lubricated, possibly replaced.
Where is the transmission governor on a 1998 dodge ram 1500?
The engine computer controls a electronic solenoid on the valve body. There is not a mechanical governor in a 1998 Ram transmission.The engine computer controls a electronic solenoid on the valve body. There is not a mechanical governor in a 1998 Ram transmission.
Will a 46 re transmission interchange with an a518 transmission?
No, the 46 RE has an electronic governor, while the A518 has a mechanical governor.
How do you fix the speedometer cable on a 1997 Honda Accord you think it needs to be greased.?
There is no speedometer cable - all is electronic. A speed sensor mounted on transaxle connects to the back of your speedometer cluster, and trasmits that way. It's not mechanical like old cars.
1989 F150 4.9What if the speedometer does not work and you have replaced the speed sensor and checked fuses Any suggstions?
if i remember correctly they did not start using an electronic speedometer in f150's till 1992 so your vehicle should still have a mechanical speedometer which has a cable ran down to your transmission. the sensor on the rear differential on those models is an abs sensor on 92 and later its the abs and speed sensor.
