Front-To-Back Reduction Parts Install Procedure

 

This install should be performed before the side-to-side reduction parts have been installed.

 

1.  Remove the shift knob and boot assembly.  Do this by simply unscrewing the shift knob and unsnap and remove the center console piece which holds the shift boot, exposing the shift linkage. On the Passat, also remove the rubber sound-proofing boot. Set the boot parts aside.

 

2.  Finish exposing the shift linkage.

 

On the Corrado, you now want to remove the front section of the center console.  To do this, follow these steps.  On the Corrado, remove the rear ash tray by pulling it up and out.   Using a stubby Phillips screwdriver, remove the forward-facing Phillips screw inside the front of the hole vacated by the ash tray.   Next, engage the parking brake fully.   Next, remove the Phillips screw under the front of the handbrake handle.   Next, remove the handbrake grip by pressing the tab on the lowest point of the handle and then slide it off toward the front of the car.   Remove the center section of the center console.  The front section of the center console on the Corrado (says "Karmann" on it) is held down with two 10mm nuts and washers.  After you remove these nuts and washers, lift the center console out.  It may be helpful to rotate the center console counterclockwise as you lift it off.  It takes some finesse to get it out so take your time!  If you have any questions, consult your Bentley manual for specifics on how to remove the center console on your particular car.

 

On the Passat, Jetta III VR6 and TDI, and on the A3 GTI VR6, remove all of the fasteners (1, 2, 3, 4, 5) for the center consoles. Do not remove the center console completely on the A3 cars.  The center console can be lifted up enough to complete the install on these cars after all fasteners have been removed.  Remove the center console completely on the Passats.

 

3.  A bracket is welded to the front of the side-to-side pivot axle, and is held in place by at 13mm bolt.  On all cars, remove the 13mm bolt which holds the side-to-side pivot axle bracket in place.  This bolt faces the front of the car.  Also, on the Corrado, Passat, Jetta III VR6 and TDI, and A3 GTI VR6 only, remove the front bolt that holds the shift mechanism sheet metal box to the aluminum frame.  This bolt must be removed on these cars because it prevents the side-to-side pivot axle from being slid forward out of the shift linkage mechanism.

 

4.  On the Corrado and all A3 cars you must remove a small section of the sheet metal flange directly in front of the side-to-side pivot axle.  The portion you remove must run from the centerline of the car to the mid-point of the right front corner of the flange.  Use a Dremel tool to remove this flange.  Remove that section of the flange completely so that there is no raised portion remaining in that area.  This is especially important with the Corrado as there is very little clearance to remove the pivot pin.  Also on the Corrado only, after the notch is removed, place a large chisel longitudinally on the body sheet metal directly in line with the axis of the side-to-side pivot axle.  With a large hammer, hit the chisel once or twice to make a very, very slight indentation in the body sheet metal.  Also on the Corrado only, remove the rear bolt that holds the aluminum shift assembly to the car's center tunnel.  This will allow the pivot pin to be maneuvered out of the aluminum shift assembly.  Finally, on the Corrado only and with a Dremel tool, remove the small lip of the bracket welded to the side-to-side pivot axle.  All of these things are done on the Corrado to allow the side-to-side pivot axle to slide forward and come free of the remaining shift lever components.

 

Please note that on the A3 VR6 and TDI cars, only the notching step is required in step #4!  Notching is not required at all on Passat.

 

5.  On the Jetta III VR6 and TDI, and A3 GTI VR6 only, cut a small notch in the carpet and/or sound deadening material to fully allow the side-to-side pivot axle to be slid out of the shift mechanism.  On the Passat, a small cut in the foam sound deadening material can be made to facilitate the removal of the pivot pin.

 

6.  On all cars, slide the side-to-side pivot axle forward and out of the aluminum shift housing.  The Corrado pivot axle is more difficult to remove since it sits so low in the car.  All of the steps in #4 should make the pivot pin easier to remove on the Corrado.

 

7.  On all cars, remove the special circlip from the front-to-back pivot axle.

 

8.  Lift the mechanism out of the aluminum shift housing and slide the sheet metal pivot toward the passenger side of the car and set it outside of the car since it is greasy. 

 

9.  Remove the front-to-back cable from the shift lever by removing the special cotter pin from the cable shaft.  Be careful not to lose it, though an extra cotter pin was sent in case you do lose the original.  Make note that this clip is not made of ferrous metal and is thus not magnetic.  You will have to fish it out of the shift box with your fingers if you drop it in there.  It also likes to fly away when it is removed, so watch your eyes!

 

10.  Remove the stock shift lever from the car.

 

11.  Remove the dieselgeek.com shift mechanism from the bag and try not to remove the grease that was applied to it.  Re-grease the pivot bushings with your favorite brand of white/yellow grease if you have any questions as to whether there is sufficient grease on them.  Don't disassemble the shift lever assembly since it is fully greased under the plastic bushings.

 

HIGH PERFORMANCE TIP! Install two 8mm bolts and nuts in the vacant holes that VW left in the aluminum pivot frame assembly and the body sheet metal. These added bolts tie the sheet metal shift box more securely to the aluminum pivot frame.  This sturdier platform will make the assembly stiffer, which makes the shift mechanism feel more solid.  Volkswagen must have saved some money by not using these two holes.  Most hardware stores carry this hardware.  The nuts and the hex heads on the bolts should be 13mm or 5/16”.  Tighten to 20 pound feet if you have a torque wrench.

 

On the Corrado, hold the aluminum pivot frame loosely in place with the original rear bolt that the factory did install.  Next, from inside the aluminum pivot frame, insert an 8mm bolt through one of the above mentioned "extra" holes.  This bolt will be installed "upside down" with the head down inside the aluminum pivot frame and the threads coming up through the hole.  Loosely insert a nut on this bolt.  Repeat this with the remaining bolt and nut.  These nuts/bolts will be tightened in Step #16.  When it is time to tighten them, use the following procedure: use a 13mm wrench to hold the head of the bolt inside the aluminum pivot frame.  Tighten the nut using a 13mm socket wrench.  Tighten to 20 ft/lb.  Next, install the original front bolt holding the aluminum pivot frame in place.  Tighten the 2 original bolts (front & rear) to 15 ft/lb.

 

12.  Reattach the shift cable to the new shift lever.  Slide the cotter pin through the hole in the cable pivot shaft.  This can be mildly tedious as the cotter pin hole is pretty small.  An extra cotter pin has been provided in case you lose the original cotter pin. 

 

On the Corrado, remove the shift cable retaining cotter pin from your new short shift kit.  Next, lower the shift lever/sheet metal bracket assembly (the assembly shipped to you by dieselgeek.com) down into the aluminum pivot frame.  Attach the shift cable to the pivot shaft on the short shift assembly and reinstall the cotter pin.  Space is tight, so be patient.  Lower this assembly so that the 11mm plastic-sheathed ball at the bottom of the bracket goes into the grooved bracket on the right side of the shift mechanism.  Line up all of the holes that the side-to-side pivot axle will travel through.  Carefully insert the side-to-side pivot shaft from the front.  As the shaft approaches it's rearward most position, insure that the bracket at the forward end of the shaft rests between the two spring ends on the sheet metal bracket.  For the Corrado, now go to Step #15.

 

13.  Slide the new sheet metal pivot bracket's pivot pin into the shift lever's plastic bushing and reinstall the special circlip to the end of the front-to-back pivot shaft.

 

14.  Lower the mechanism back into the shift box, guiding the 11mm plastic-sheathed ball which is welded to the bottom of the sheet metal pivot bracket into the grooved bracket on the right side of the mechanism.  Once fully lowered, push the side-to-side pivot shaft back through the sheet metal bracket's new bushings and guide the end of the pivot shaft in between the two spring ends on the sheet metal bracket.

 

15.  Replace the 13mm bolt removed in step #3.  This bolt’s head faces the front of the car.  Tighten it in a position that places the shift lever nearly perfectly vertical.  Tighten to 15 foot pounds and no more!  It strips rather easily. 

 

16.  Replace the front bolt that holds the shift mechanism sheet metal box to the aluminum frame.  Don't over-tighten this bolt.  Tighten to 15 foot pounds and no more!  It also strips rather easily.

 

17.  Reinstall the center console. 

 

18.  Reinstall the shift knob and boot.  Simply put the shift boot over the shaft and screw the knob onto the shaft, centering the engraved/embossed shift pattern when fully tightened. Reattach the shift boot to the center console.

 

19.  Install the newly redesigned side-to-side reduction pin and adjust the linkage as described here.  If for some reason you do not want to install the side to side reduction pin it is very important for you to know that you may still need to adjust the linkage as described here.   Also, if you have an A3 GTI or Jetta or B4 Passat, you should install the new Dieselgeek.com high performance front/back cable end bushings immediately before you install the side to side reduction pin.  (Corrados came equipped with square-headed cable ends and cannot use the hard plastic oval bushings we supply to the other shift kits.)  These upgraded custom bushings replace the spongy black rubber bushing that is currently installed in the end of your stock front/back cable end.  This mod was designed to make your A3 GTI/Jetta GLX or TDI and Passat shifter feel like the highly sought after MkIV Sigma shifter!  The install is as simple as unbolting the shift weight and front/back cable end while being careful not to lose the thick 8mm washer and square nut that are just below the shift cable.  When you have removed the bolt holding the shift cable to its shift bracket, hold the cable end with one hand and push out the black rubber bushing with your fingers.  You’ll be left with an empty oval ring to put the new bushings into.  Then lightly grease the new white plastic bushing’s round inside holes.  Place one of the bushings on the bottom of the shift cable end and place the other on top of the cable end.  Then you just simply bolt the cable end back to the front to back bracket, roughly centering the shift cable in the adjustment slot.  Replace the shift weight (if your car has one) after you have tightened down the bolt holding the shift cable end.  You are done.
