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

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.

Hi Ken, thank you so much for contacting us. The 1388-M does not include a sensor. For use with a TH350, you'll want this sender (5291). Hope this helps!

Thank you so much for contacting us. While the 5291 would work great if you were driving an AutoMeter speedometer, it will not work with the factory equipment on your vehicle. The Chevy PCM really wants to see the Chevy speed signal, which was a sine wave (as opposed to the square wave output from our sender). Sorry for the bad news.

Hi there, thank you for the question. Unfortunately, the 5291 cannot be changed from the 16 pulses. We have another style sender that is 8 pulses per rev, but 4 pulses seems very rare and unlikely available as an aftermarket sender option.

Hi Stewie, thank you for the question. If this is an AutoMeter electric speedometer, it should work off the VSS (vehicle speed sensor) on the later model transmission. The AutoMeter style sender 5291 will only work on an early model transmission with a cable output for the speedometer.

Thank you for the question. Ford had begun using a VSS (vehicle speed sensor) as early as 1989, even though they had a cable to run the speedometer. If your F150 is equipped with a VSS, our electronic speedometer will work directly off your VSS. Otherwise, you will actually need the 5292 Ford Plug-In style sender to run our electronic speedometer: https://www.autometer.com/hall-effect-speedometer-sender-ford-plug-in.html In any situation, however, our sender is not designed as a direct replacement for an OEM sender. We would recommend sourcing this directly from Ford.

Thank you so much for the question. There are a few things you can check out. First of all, we do have a video on our YouTube channel with instructions on testing a 3 wire speed sensor: https://www.youtube.com/watch?v=G1XzwZE6n8M Also, try testing the sender with a drill outside of the transmission to see if it will trigger the speedometer then. This could be caused by the drive key not engaging while the sender is installed. To fix this you can adjust the collar on the drive key so that it extends farther into the trans. Finally, be sure the sender's ground and speedometer's ground is shared. Ideally, we recommend both the sender and speedometer be grounded to the transmission.
