I have a 2000 Dodge Caravan. After hitting a dip and bottoming out, The tranny is stuck in low gear and the speedometer is not working. Any ideas why?

output speed sensor viewed from front below it is the one closest to driver side frame rail and is easy access [the input speed sensor is hidden behind the wiring harness and transaxel computer closer to bell housing ] note the connector for this sensor may be corroded inside . a soldier in pigtail connector is available from chrysler as well as an updated sensor [note do not use crimp style connectors for this job --use only 60-40 rosin core [radio soldier] then cover soldier joint with heat shrink tubing then tape back into harness neatly] if you do not possess good soldering skills leave job for trusted mechanic. this is not a time consuming job and even at retail the sensor and pigtail are inexpensive

Sounds like the cable harness that connects the tranny to the vehicle computer is damaged and may be shorting out. That's a guess, of course. Speedo not working: same conclusion. That'd usually be a dealer only item, but shouldn't be that expensive, but it'd be labor intensive, as the mechanic must cut away the old harness and put in a new one, and clean the matching parts on the tranny.

From the speedometer going out, it sounds like the Vehicle Speed Sensor has stopped transmitting vehicle speed to everything that uses it - the speedometer, the PCM etc. If the PCM doesn't have a VSS input, I would expect it to shift very badly.
I would also expect it to have lit the "Check Engine" light, so I'm surprised that you didn't mention that.
Anyway, bottom line, something has gone wonky with a sensor, and that's gotta be fixed. Loose plug, damaged wiring, broken sensor, whichever is required.

Bet you a milk shake that your output speed sensor has either come unpluged or broke. Or the wire going to the sensor has broke. On the rivers side of the car if you take the upper air filter housing off and look down to the front side of the trans you will find two sensors. One is beneath two cooler hoses and the other one is farther to the drivers side or tire. The outer one is the one you need to check.

Your masterpiece is equipped with a 1987 transmission model known as A604. It's so bad that chrysler was forced to change its name to 42LE. It has 100% failure rate, and is likely the worst trans ever built - despite literally hundreds of "upgrades", chrysler still can't make it run.
Any problem the computer senses sends it into limp mode (2nd gear), and in your case it's likely related to a faulty speed sensor.

it is an costly lesson. you have lucked out and basically shorted the regulator interior the alternator. if it is so, the ecu isn't getting the right 12 volts and could no longer perform suitable. replace the regulator, or the full alternator in case you haven't any longer completed it till now, AND replace the battery on a similar time.
