INSTALLATION INSTRUCTIONS
This kit is for the GM 4L60E 4 speed automatics to all Toyota Land Cruiser 3 speed transfer case. The design of this
kit utilizes two shafts. The first shaft is your 4L60E output shaft that is cutoff to the length illustrated on page 3. With
the shaft cut to the proper length, the new Advance Adapter spud shaft can now be put into position. The new spud
shaft should be pressed into the new rear bearing so the external snap ring is towards the threaded end of the shaft. With
the bearing on the spud shaft, you can now install the assembly into the back portion of the adapter. The external snap
ring will lock the spud shaft into position. The threaded portion on the end of the spud shaft will be identical to the 3 speed
transmission being replaced. The original gears, bearing, washer and nut will all be reused onto the new spud shaft. On
the right side of the adapter, you will be able to mount the special shift bracket illustrated on page 4. This bracket should
position your shifter in the original floor board location. Use the stock metric bolts to bolt the transfer case to the adapter
housing.
GM 4L60E 4 SPEED AUTOMATIC:
When installing the new transfer case adapter, make sure that the coupler and the output shaft do not bottom out. We
have found on occasion that a transmission output shaft may be slightly longer than we have allowed for and when coupling
into our new spud shaft, we find a small amount of interference. The adapter housing and spud shaft must be assembled
to the back of the transmission without interference.
DO NOT FORCE THE NEW TAILHOUSING ONTO THE
TRANSMISSION. If assistance is needed, please feel free to call us toll free number at 1-800-350-2223.
When assembling the adapter housing to the transmission case, we have provided you with a new square type "O"-ring
seal to prevent fluid leakage. This seal is a stock GM item that is used on all 4L60 installations. On most installations,
a slight pan modification may be required for clearance of the front Universal yoke.
The Advance Adapter casting has been drilled for your new sensor. The sensor should be installed and the gap between
the sensor and the ring should be .010" to .012" air gap.
CAUTION: Advance Adapters has designed this kit to use the stock seal in the transfer case as a barrier between
the 4L60 and the Toyota Land Cruiser transfer case gear boxes. You should inspect your stock seal and replace
if necessary before installing this adapter kit. This kit also uses a sealed bearing to aid in the isolation of fluids.
NOTE: Periodically check both your 4L60 fluid level and your transfer case fluid level for fluid contamination.
If fluid contamination occurs, you should switch to ATF in your transfer case.
