sensor still line up properly. RTV Blue Silicone should be used to seal the 51-0405 adapter to your 4L60E
transmission. Screw the 300619 sensor completely into the 51-0405 casting. With a feeler gauge, check the gap
between the sensor and the reluctor ring. This gap should be around 0.010" to 0.012". Once 0.010" to 0.012"
clearance is obtained, loc-tite the sensor into position. You are now ready to bolt your conversion adapter to the 51-
0405 kit.
NOTE: On a few applications, customers have not positioned the clamp in the incorrect position
which has caused interference with the coupler shaft in the conversion adapter. If you try bolting the
conversion adapter up to the 51-0405 and find interference, the coupler may be hitting the clamp on the
reluctor.
With the 51-0405 installed the rear of the transsmission should now have a square bolt pattern that uses 4 bolts. There are several
various lengths of output shafts that these transmissions has been furnished with. You must make sure the proper shaft has
been installed into the transmission for use with our transfer case kit. The speed-o-meter gear is normally located in the
tailhousing, but when adapting it to the transfer case, the location will change to the back side of the transfer case.
Make sure the bearing retainer clip found on the front side of some transfer cases is removed prior to assembly of the new
adapter. This clip was used to retain lover bearing in Toyota transfer case.
The coupler in this kit is made for a 21 spline male shaft that protrudes from the front of your transfer case. When replacing
transmissions that were equipped with turbo-charged engines, you will need to use a 23 spline coupler in place of the 21 spline
coupler furnished with this kit.
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 coupler must be assembled to the back
of the transmission without interference.
DO NOT FORCE THE NEW TAILHOUSING ONTO THE TRANSMISSIONS.
If assistance is needed, please feel free to call us on our toll free number (800) 350-2223.
When assembling the adapter housing to the transmission case, we have provided a new square-type "O"-ring seal to prevent
fluid leakage. This seal is a stock GM item that is used on all installations.
All installations will require the use of a transmission cooler. The cooler can either be installed in the radiator or a remote location
is acceptable. The transmission shift control can either be a Hurst floor mounted type shifter or sometimes the existing column
shift can be modified on certain applications.
The linkage on the Toyota transfer cases will vary. Some have the control lever on the tailhousing of the transmissions while
others have it on the transfer case. This adapter can be used with either style. If the opening is not used on the top of the new
housing, you will need to cover the square opening.
If you have a 1989 - 95 electronic fuel injected 4 cylinder. The transfer case shifter linkage was relocated on the 5 speed tailhousing.
The shifter mechanism for both the transfer case and the transmission were one unit. When using this transfer case with any of
our transfer case adapters, you must either modify or replace your transfer case. By changing the shifter rods from a 1984-88
(Carbureted 4 cyl.) transfer case or using Toyota part numbers 36314-35020 (high-low rod) and 36313-35020 (front drive rod), you
will be able to retain your stock transfer case. The other option is to purchase a 1984-88 (Carbureted 4 cyl.) transfer case.
