SPEED SENSOR, MECH TO ELEC, GM & CHRYSLER, 7/8"-18 THREAD, HALL EFFECT, 16 PULSE

Hi Scooter, thank you for the question. To drive a mechanical speedometer with a 4L460E trans that features an electronic VSS (Vehicle Speed Sensor), you would need some type of electronic to mechanical conversion. Basically the opposite of our 5291 sender. There are a few out there in the marketplace, but we do not currently offer one.

Thank you for the question. Our 5291 is designed to thread onto a GM style 7/8-18 threaded style cable output. If you have a cable output/speedometer drive gear that is not threaded, it will need to be replaced (if possible) with a threaded style. Otherwise, if there is no electronic signal present in the form of a VSS, you will need to provide some type of alternative method to drive the speedometer like a 5289 GPS sender or a universal sender, such as our 5290.

Thank you for your question. As long as it still has a drive gear with a threaded output a speedometer cable would normally attach to, yes, you can attach this directly to that.

Hi Julian, thank you for the question. On a later model transmission that was originally equipped with a VSS, we'd recommend getting the proper Toyota VSS replacement. If it's an earlier model with a cable output, to run an AutoMeter electronic speedometer you'd need to run either a GPS speedometer or sender or our 5290 universal sender.

No, it mounts directly to the transmission, replacing the OEM mechanical speedo cable. Easy to mount, just "bolts" right on, but make sure you have the correct size - there are two. I mounted mine on a TH350 trans, which required the 7/8" version. Then run 3 wires, +12v (can grab that from the starter or battery, or fuse box), ground (can use a transmission case bolt), and the speed signal, which runs to the speedometer (can run it where the OEM cable you are replacing ran).

Thank you for your question. Our 1388 speedometer can connect directly to the VSS on your transmission. 5291 would be used to convert from a speedometer cable to an electric speedometer.

Hi Steven, thank you for the question. Yes, this sender (5291) along with any AutoMeter electronic speedometer can be calibrated to your Jeep using our simple "push the button, drive 2 miles, push again" calibration. A GPS Speedometer would also work and would avoid any connection to the transmission and would be calibrated right out of the box.

Thank you so much for contacting us. Unfortunately, this, or any of our senders are probably not going to work to drive your PCM. The PCM is looking for a sine wave signal at a very specific pulse per mile rate. This outputs a square wave signal at a different rate. These are designed to drive our gauges. You'll want to use the output from the transmission your PCM is looking for. Sorry for the bad news.
