4L60-E Reluctor Ring Relocation

Reluctor Ring Relocation

Installing the reluctor ring (Stealth Conversions Part #4L60-002 for 1.42" i.d. or 4L60-003 for 1.30" i.d.) in the governor area is a requirement on the 4x4 applications, but on the 2-wheel-drive applications, this is the lowest cost way to run the speed sensor and speedometer cable, because it doesn't require a modified tailhousing.

When relocating the reluctor ring to the governor gear location, the speed sensor (GM part #15547452, retail price $72), can be mounted on the driver's side or the passenger's side (shown on both sides in the photo above).

On 4x4 applications, the shift linkage to the transfer case may interfere with the sensor if it is installed on the driver's side, so mounting the sensor on the passenger's side is the obvious solution.

Installing the sensor requires drilling and tapping a 3/4"-16 UNF hole into the transmission case. The wall thickness of the case is 5/16" in the areas shown, which gives five full threads of engagement. When installing the sensor, coat the threads with epoxy, then screw the sensor into the case until it just touches the reluctor ring, then back it off 1/2 turn. This gives a .030" gap, whch is ideal. Epoxy putty should be built up around the sensor on the outside of the case to hold the sensor securely in place.

Many people fear drilling and tapping a hole into the transmission case — the case is aluminum, and it is an easy job to drill and tap. The positioning of the hole is not that critical, and the drilling can be done with a hand-held electric drill. To keep aluminum chips from getting into the transmission, put a piece of tape over the oil return hole (about 1/2" diameter), and put a piece of tape over the oil spray hole (see page 12-13 of manual). After drilling and tapping the hole, wipe the area clean with a paper towel and remove the two pieces of tape.

More information on alternative ways to drive a speedometer cable on the 4L60-E transmission is available in the book, Chevrolet TPI & and TBI Engine Swapping.
