Short Throw Shift Kit Install Guide for G- and R-series Transmissions

Product link: http://www.marlincrawler.com/transmission/shifter-parts
Also available in PDF format in our Tech Section: http://www.marlincrawler.com/tech/guide/transmission-short-throw-shifter-kit-installer

Thank you for purchasing our Short Throw Shifter Kit! This guide will help you install this kit onto a G52/G54/G58/R150F/R151F transmission. Please carefully read and familiarize yourself with the following procedures before installation.
If you have any questions, visit http://www.MarlinCrawler.com or call us at (559) 25-CRAWL

This kit is comprised of the following components:
  • (1) Modified Short Throw Handle with Marlin Crawler Heavy Duty Shift Socket and Toyota Boot
  • (1) Short Throw Shift Base Assembly
  • (1) HD Shifter Seat
  • (4) 20mm X 8mm X 1.25mm Base Bolts
  • (4) 8mm Lock Washers



Prelude: Your transmission will be exposed during this installation process. Be extra careful to clean your interior or workspace to minimize the risk of any debris or foreign object from falling into your transmission. Also, note the direction of your shift handle as our new handle may be installed in two different orientations and only one will match how your handle is now.

To begin, engage your emergency brake and shift your truck into neutral. (Shifting into netural will make the reassembly process much easier so don't skip this!) Remove your shift handle boot from your shifter base. Push down and rotate the shifter retainer counter-clockwise to unlock the shift handle as shown in the following image:



Next simply lift the shift handle up removing it from the base. Remove the four shift base bolts using a 12mm wrench or socket.



Using a brass drift, brass hammer, and/or flat head screwdriver, gently repeatedly tap on the stock shifter base until its seal is broken. You may also tap on the sides of the shift pivot pins.

With the seal broken, simply lift the base off the transmission flange. There is an oil slinger between the shifter base and transmission housing. This oil slinger may come off with the shift base (as shown below), or it may remain on the transmission housing.

Be sure to mark which side of the oil slinger is facedown towards the transmission to prevent confusion during reassembly.



If your transmission does not have a factory oil slinger, we highly recommend you use one. Our breather is designed to work in conjunction with this slinger. Without it, its likely oil may splash out the breather. The Toyota part number for this is 33144-35030.

Remove the oil slinger by gently pealing it away from the shift base or transmission housing. The slinger is a type of sheet metal and can be easily bent and formed back into its original shape.



Remove and clean all paper gaskets from both sides of the oil slinger and from the transmission flange. Paper gaskets are used from the factory, however, they commonly leak and are often replaced with silicone. Therefore, you may encounter silicone instead of the original paper gaskets as shown in the images here.

While cleaning the transmission flange, position and move your gasket scraper away from the transmission opening being extra careful not to drop any debris inside the transmission. It may be helpful to place a clean towel or rag inside the transmission opening.



After all gasket material or silicone has been removed, degrease the sealing surfaces of the transmission housing, Short Throw Shifter Base, and both sides of the oil slinger.

This is a very important step to prevent future leaks. Silicone and oil repel each other and a seal cannot be established if any oil residue (including grease) is present. It is therefore imperative that all sealing surfaces are void from all oil and grease!

Apply a thin layer of silicone sealant on the flange of the transmission housing as illustrated in yellow in the picture below.
Note how it is unnecessary to apply sealant to the outer parameter of each bolthole since the seal is already established to the inside profile of the bolt pattern.

Carefully lay the oil slinger atop the transmission flange, noting which side is facedown (as marked earlier) and its orientation with the shift shoe inside the transmission.

Apply a thin layer of silicone sealant to the Short Throw Shift Base in approximately the same contact location as the flange of the transmission housing, as illustrated in yellow in the following picture:



You may find it is easier to apply silicone to the housing and the base rather than the two sides of the oil slinger. Trying to hold onto the thin slinger with fresh silicone on each side is difficult. Therefore, don't apply any silicone to the oil slinger at all: Add silicone to the transmission flange and the short throw base and simply place the slinger between them.

Lower the Short Throw Shift Base vertically into position. Be extra careful not to carelessly lay the base in place as the slinger may move around needlessly smearing the silicone.

With the Base and slinger installed, proceed to install the four bolts with lock washers. Don't tighten the bolts too much at this time yet.



Please note that for R151F Turbo applications, the shifter base and oil slinger are flipped and positioned 180-degrees from what is shown in these images. Please be sure you have the shift holes aligned with the shift shoe inside the transmission before tightening the base down.

After all four bolts are lightly tightened, torque each one to 12 ft-lbs in a crisscross pattern to prevent the silicone from squishing out sideways.

You are almost done!

With the base in place, it's time to install our Heavy Duty Shifter Seat. To do this, rest the seat up side down atop each pivot pin, and then rotate the seat around and down into the base as shown in the following image sequence. The concaved radius should be facing up once installed.



Apply a generous amount of grease to the Heavy Duty shift seat. This step is not critical, as oil will eventually splash up and lubricate the seat, but it is recommended for immediate shifting performance.

If you are wondering if this is safe or not, keep in mind that grease is oil based and is safe for all internal transmission parts. If you don't have grease, you may use motor or gear oil as a substitute.

In addition to our Heavy Duty Seat, we have included our Heavy Duty Socket, which you'll find pre-installed and attached to the end of the modified shifter. The socket needs to be positioned so that it is perpendicular to the shifter and ready for direct installation. Please note that we have engineered our H.D. Socket with a tight and a precise fit. Therefore if it is tilted even slightly to the side on the end of the shifter, then you will struggle trying to insert the shifter into the transmission. The handle will insert with very little effort if everything is properly aligned.

Lower the shift handle down into position in the same orientation as your original handle (remember you noted this before removing your stock lever). Align the slots of the shift handle and shifter retainer with the shift pins of the Short Throw Shifter Base as shown in the following image.



The shift handle will continue to insert into the transmission until the shifter retainer rests (without force) near the top level of the base as shown in the below image. If your retainer is not in this position, then double check the shift socket's alignment with the shift shoe inside the transmission as discussed above.

As mentioned ealier, because the transmission was shifted into neutral, the shift shoe within the transmission will be lined up directly with the hole of the shift base. This makes for a straight and easy insertion of the shift handle.



Push the shift handle retainer down until it stops, and then rotate clockwise to the right approximately 35-degrees. The retainer is 'locked' when its two sides are parallel with the transmission, as shown below.



Shift through all forward and reverse gears to ensure proper operation! Finally, push the shift handle boot down and over the top of the Short Throw Shifter Base and you're done!



Closing notes:
There is no break-in procedure; it is ready for use immediately. If you ever need to remove the shift pivots or breather, please use thread lock during reassembly to keep the parts tight and to prevent oil leaks.

wow,how awesome.
Thanks lunasicc! For more than a decade we've been selling two piece short throws and we are equally excited along with many, many people to see this long anticipated one-piece version come to fruition!

i have an idea, how about you work on getting some gear sets in stock instead of worring about a short shifter kit.
Our 4.70:1 gear sets are nearly in stock, only about a week out now. Using Toyota's own gear cutter to produce our high quality gear set in Japan is a lengthy process. Once the ball is set in motion we can't do anything to speed up the process, so it's nice that we can focus on other projects for our customers to keep our product line growing with more innovative and feature rich kits.

While there are people like yourself who are excited for the best 4.70s on the market, there are equally as many who are ecstatic to see us release the best Short Throw Kit on the market! :thumbs:

what a joke
Oh its no joke at all! Cut from USA-made 6061-T6 Billet Aluminum, Anodized Marlin Crawler Red, Laser Etched text, the World's Best USA-made Heavy Duty Seat and Socket, Grade 10.9 American-made Shift Pivots that are a World's first serviceable, with a Genuine Toyota oil-baffled vent breather, Genuine Toyota Shift Handle and Genuine Toyota Shift Boot, this is the nicest Short Throw Kit on the market by far!
