changing the gears in a rear will mess up your speedometer. you need to reset the computer through a hypertech power programmer or some equivalent programmer.
It could, vehicle speed is very important in shift scheduals
might be your wheel speed sensor for your speedometer but with the tranny jerking just use Valvoline high Mileage tranny oil changing it did the job for me
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.
You can fix the speedometer in your 1994 Oldsmobile 98 by replacing the speedometer cable. If changing the speedometer cable does not fix your speedometer you will need to replace the entire speedometer.
There is no point in changing it.
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.
A mechanic man can do that job for you
Yes, they will affect your speedometer, unless you have it recalibrated (changing internal gears in mechanical models, or reprogramming for ECM controlled units). Same holds true for changing rear end ratios.
Could be a loose cable (connection on the back of the speedometer). In today's electronics on cars it's best to take it to a mechanic who knows what they are doing for the repair. You might want to save the money, but if you mess something else up trying to fix the one thing it might cost you even more.
Take it 2 a repair shop idiot
Take to local shop have them Run a ABS scan they can tell you why. Cost is approx $80.00
keep it from changing on time
