General Information

Shifter/shift knob thread size: 12mmx1.50

 

Clutch in at red lights? Keeping the clutch pedal pressed in at red lights is not necessarily a bad thing, but it puts more wear and tear on the throw-out bearing.

 

Using the transmission to hold the car while stopped on a hill?  Don't do it, unless you can afford to replace the clutch at regular intervals.  Please use your brakes when stopped on a hill.

Clutch

Stiff Clutch Pedal

If the clutch pedal is difficult to press, replace the clutch cable (don't bother trying to adjust it; it's a $16 part... buy it, install it, adjust it to specs and drive happily ever after). While you're at it, inspect the clutch cable carrier tube at the firewall (this tube can fail if the cable is not adjusted at regular intervals and/or if a stiff cable is allowed to saw through its protective sheath).  If the tube is found to be broken, it'll need to be repaired.

 

Clutch Went to the Floor

  • Clutch cable broke
  • Clutch cable carrier tube at the firewall broke
  • Clutch assembly broke
  • Clutch release arm broke
  • Throw-out bearing went bad
  • Pushrod is stuck
  • ...or any combination of the above

Drive gears are sold separately from the speedometer cables.

Drive gear securing ring part number: N 900 154 01

What if the speedometer cable gear has fallen into the transmission?  Do your best to get it out.  A lot of folks have never had issues with roving speedo gears, while others have needed repair work due to the gear (or parts of it) getting jammed into transmission components.  Don't become a victim of the latter.
020 Manual Transmission

Recommended by VW: SAE 80W hypoid oil; API service GL-4; Mil-L-2105.

Recommended by other VW owners: Redline MTL; Redline MT-90; GM's Syncromesh; Pennzoil Syncromesh; Brad-Penn.

Do NOT use GL-5 oil.  The syncros in your transmission are brass; GL-5 oil will break down the brass and will essentially destroy your transmission.
