FORD T&C TOP LOADER 4 SPEED (RUG):
The Ford Top Loader transmission that is compatible with Advance Adapters kits must have a case length of 10-1/4" and
the material must be cast iron. The casting part numbers could be C8AR-7006D or D2AR-7006CB. The gear shift linkage
is on the left side of the case and the inspection cover that is mounted on the top must be held down with ten (10) bolts.
This transmission is sometimes referred to as "RUG" or "HEH" . The RAD transmission which is an aluminum case that
is only 9-3/16" long is not compatible with this kit. The RAD can usually be identified by the shifter that is in the top of
the tailhousing.
The new main shaft's position on Jeep and Toyota installations is determined by the fixed gear in the transfer case. If the
transfer case gear is not installed properly with the correct bearing, then the position of the new main shaft in your
transmission will be incorrect.
When assembling the Advance Adapters new main shaft with the original gears, make sure that all of the gears have
sufficient end play for proper lubrication. This should be done while assembling the gears and after assembly to the transfer
case. If the shaft that you have received with the kit does not compare to your original shaft, it is very possible that you
may have received or purchased the wrong adapter kit.
This transmission has two shift rails that extend out the rear side of the case. All of the Advance Adapter kits have clearance
holes drilled into the adapters so these two rods can extend backward without interference. It is best to shift all four gears
on the work bench prior to assembly into the vehicle to make sure the proper depth and clearance has been maintained.
If you cannot fully engage each gear, then the rod may be bottoming out inside the clearance hole.
