Auto Meter GM/Dodge Speed Sensor, Mechanical to Electric New
Auto Meter GM/Dodge Speed Sensor, Mechanical to Electric
AutoMeter vehicle speed sensors generate the signal you need to make installing an AutoMeter electric speedometer in your vehicle quick and easy. Compatible with GM and Chrysler transmissions with a 7/8" -18 threaded speedometer cable output, this vehicle speed sensor outputs a 16 pulse per revolution (PPR), 12v square wave signal. Featuring a mechanical cable output, this sensor has the ability to retain the mechanical cable in applications with mechanically driven cruise control.
Control your torque converter from the palm of your hand with the AlliLocker™ from Fleece Performance Engineering.
The AlliLocker™ is 100% code free* when used on the track and allows you to bypass the TCM to lock/unlock the torque converter on demand. Turn the bypass switch off, and the TCM regains control of the torque converter clutch.
*The AlliLocker is NOT desinged to be used on public roadways. If used on public roadways, the AlliLocker may set a DTC causing a range shift inhibit. This can typically be cleared by a key cycle. When used on the sled pull or drag race track, where there is only one lock event, the AlliLocker will not cause a range shift inhibit.
The Allilocker™ operation is simple. Leave it in normal mode until you want control of the torque converter clutch (TCC). When you engage bypass mode (left rocker switch) the TCC is completely controlled by the pushbutton on the right (it is a latching pushbutton). If you press it down it locks the TCC and stays locked until you push it again which raises the switch back to the open/unlocked position.
GM/Duramax Allison 6 Spd Transmission Neutral Safety(PRNDL) Switch. When this sensor goes bad, you'll likely get a "shift range inhibited" message on the message center along with a flashing light under the gear or range you are attempting to shift to.
The vehicle is equipped with a column type shift selector. In addition to the column shifter, another component associated with the shift selector is the Neutral Start Back Up (NSBU) switch mounted on the selector shaft of the transmission internally. The NSBU switch transmits the gear selector position information to the TCM. The NSBU switch mounts inside the transmission housing, in the valve body, and detects the angular position of the shift selector shaft. This position is communicated to the TCM so that certain vehicle control functions can be coordinated with the position of the shift controls. The neutral signal output of the NSBU switch is typically used as confirmation that the transmission is in NEUTRAL or PARK before the engine starter is engaged.
