Creepy Twin T-Case Shifter
(Top Shift)
Twin stick shifters allow independent control of the high/low and 2wd/4wd sections of your Toyota gear driven transfer case. This allows access to low range 2wd operation. It also allows you to shift in and out of 4wd while driving on the trail without the need to stop. Access to 2wd low range allows easier steering and less driveline binding when you are traveling between obstacles on the trail. Twin shifters come fully assembled and ready to install. Before installing the Creepy Twin shifter, it is necessary to remove the interlock pin from the transfer case to allow independent operation of the shift rails. Once the pin has been removed, the Twin Shifter can be bolted on to the top of the transfer case.
Shifter bases are made from polished cast aluminum. Shifter keys are made from heat treated 1020 steel. The internal cross pin is made from heat treated chromoly steel. A splash resistant oil breather is installed on the top of the shifter to reduce oil loss in a rollover while still allowing the transfer case to vent as needed. Each lever is sealed with an o-ring for long, trouble free operation. Twin Stick shifters are shipped with one 4.70 and one 2wd/4wd shift knob. A new cork shifter gasket is included with the kit. Reuse stock shifter base mounting bolt to attach to transfer case.
NOTE: In order to make the forward shift shifter work, some minor modifications are required.

Installation Instructions:
1. Remove the transfer case from the vehicle. NOTE: If you have a dual case, it will need to be separated from the front case.
1. Continued - Place the case on a bench and remove the four bolts on the shifter with the base and gasket using a 12mm ratchet.
2. Remove the detent plug on the drivers side of the t-case using a 6mm allen wrench.
3. Using a magnetized long pin punch, remove the detent spring. If a magnetized pin punch is not available, roll the t-case over for the spring to slide out of the hole.
4. Using a magnetized long pin punch remove the detent ball.
5. Slide the drivers side shift rail forward until it stops. Insert a magnet under the shift rail to catch the roll pin.
6. With the magnet in position under the shift rail, tap out the roll pin with a punch.
7. Using needle nose pliers, remove the roll pin from the magnet. If the pin falls into the case, roll the case over and remove it.
8. Hold the shift fork in place with needle nose pliers. With a long pin punch, start sliding the shift rail out.
9. Still holding the needle nose pliers in place slide the shift rail out completely.
10. Using a magnetized long pin punch remove the interlock pin from the transfer case.
10. Continued - When reinstalling, note the orientation of the shift rail. If the shift rail is inserted into the t-case incorrectly, the t-case will not shift properly. The three grooves on the shift rail should be facing out with the one groove on the opposite side facing in.
11. Using the needle nose pliers, hold the shift fork in place while sliding the shift rail into position. Be sure to maintain the proper orientation of the shift rail (see note above).
12. Align the shift rail hole and the shift fork hole with each other using a long pin punch.
13. Once aligned, remove the pin punch and insert the roll pin using the needle nose pliers.
14. Firmly tap in the roll pin until it is nearly flush.
15. Turn the t-case over. Drop the detent ball into the hole.
16. Drop the detent ball spring into the same hole.
17. Insert the detent plug into the hole using a 6mm allen wrench. Turn the t-case back over.
18. Using the original shifter base bolts, install the new gasket and twin shifter on the top of the t-case. Torque the bolts to 8-11 ft./lbs. with a 12mm ratchet.
NOTE: When re-installing the t-case into the truck, make sure to sufficiently clearance the transmission tunnel, seats, or anything else that may come in contact with the shifter. Failure to do so may result in contact with the shift levers and can cause the shifter base to crack or break.
