The speed cluster work from the ABS speed sensors that have separate computer it is on engine compartment near battery and brake booster. This computer work independent and only get 12v and can bus send all the info by a can bus 2 wires that run to dodge ECM same wires run to cluster. I make a diesel swap speed work ok but not my RPM any ideas
If you lose the speedometer, replace the rear differential speed sensor on top. If the speedo is ok, then it's your ABS pump/solenoid unit in the engine compartment left rear side. Most of the 99's have only the rear ABS, not front so don't look at the front brakes for the issue.
From what I have read this sounds like a problem with the second speed sensor located on back at the rear axel on top of the differential. If the cable is loose or the sensor is bad it will cause the brake light to come on and the speedometer to act funny. There are two speed sensors...one in the transmission and the one on the differential. The second one is probably the problem.
ABS LIGHT ON AS WELL?IF SO..I WOULD LOOK AT ABS SENSOR IN REAR DIFFERENTIAL..GETS SPEED SIGNAL FROM THIS SENSOR AS WELL..USES ONE IN TRANS FOR TRANS SHIFTING
it sounds like it is the speedometer cable that goes from the speedometer gauge to the transmission is wearing out.unless you have done one of these before then i would suggest having someone do it for you.
My 1999 dodge 4x4 2500 diesel transmission surges back and forth between gears at 45 mph. I had my transmission rebuilt and it keeps happening. What is going on.
