How do I get the speedometer and odometer to work on a 1996 ford ranger 2.3 L with manual transmission?

i believe it has a vehicle speed sensor in the rear diff that is probably your problem as the sensor you replaced in the transmission was probably the output shaft speed sensor

If the speedometer works but the odometer does not, the problem is inside the speedometer. Probably a stripped gear.

If the speedometer is still working, but the odometer does not, most likely the cable is broken (separate drives for odometer and speedometer within a single cable) or the dash unit needs replacing...

Can be loose speedo wiring connectors under instrument panel or its issue with speed sensor on transmission.

A mechanic would check the speed sensor in the transmission.

Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

You may have a couple separate concerns. The fuel gauge if it is on empty may have a hole in the float. The speedometer odometer and trip meter is probably a broken gear in the speedo assembly. If the speedometer itself works it is getting a signal from the speed sensor.

Since your speedometers work, the problem is in the gearing to the trip and mileage odometers. Simple problem, major pain to fix but, remove instrument cluster - you'll have to remove speedo cable to get it out. Use the old Mark I eyeball to check for broken parts. Might even have to drop steering column - disconnect air bag first!
