The rear side of the transmission case will have a hex-shaped bolt pattern that uses six6 bolts. There are several output shaft different lengths of output shafts that the transmission has been equipped with, but; however, this kit requires a 4WD output shaft. THIS KIT REQUIRES A 4WD OUTPUT SHAFT.
The 4L80E transmission is normally equipped with an internal reluctor ring on both the transmission’s input shaft and output shaft. The computer needs both of these readings for the proper transmission shifting and operation of this transmissionoperating. The rear reluctor ring is not always installed into the transmission. The basic rule of thumb is 4WD transmissions up to 1996 should have a rear reluctor ring in the main transmission case. All 2WD transmissions should have the rear reluctor in the main transmission case.
The 1997 and& newer 4WD 4L80E transmissions had a sensor provisions; however, the reluctor rings in these transmissions wereas left out. Since it is expensive to disassemble the transmission to add a reluctor ring, this kit has a vehicle speed sensor built in that can be used in place of the 4L80E Output Shaft Speed Sensor.
