Gear Lever

3-synch gearbox - spring (19) pushes the lever (14) into the socket, cover (20) compresses the spring, and circlip (21) locks the cover in position:

4-synch gearbox - the retaining plate is secured with three special bolts and Thackery washers into the remote control housing:

Shouldered bolt and Thackery washer. The bolt tightens through the retaining pate and washer onto the gearbox casing, compressing the spring of the washer, which presses the retaining plate down onto the large ball of the gear-lever, pressing it into the socket in the casing:

Anti-rattle bush, with the slit arrowed:

An original bush on the left with a significant chamfer to aid insertion into the gearbox shaft socket, once the bush has been fitted to the ball-end of the cabin lever. The bush on the right is a replacement with virtually no chamfer and was impossible to fit, until I cut more of a chamfer. I tried fitting this to the gearbox first but when fitting the lever it just pushed it straight out, fortunately to fall on the floor and be retrieved. However Bill Etter was able to fit the bush to the gearbox before fitting the lever:

There is an identical bush on the other end of that gearbox shaft (large arrow). Also shown is the overdrive switch plunger (small arrow), with a chamfered head where there is OD on 4th only i.e. this V8, also later North American spec 4-cylinder:

The socket for the bush in the gearbox selector shaft (large arrow). Also shown is the reverse light switch plunger (small arrow):

Two locating pins and damper on a pre-77 4-synch, 77 and later only have one slot in the ball and hence only one locating pin:

4-synch gear lever with a rearwards kink ...

... but no sideways kink, and two guide slots ... which means the gear lever could be installed the wrong way round:

Lever with thickened section, said to be a harmonic damper, but there are still complaints that this knob buzzes. Guide pin slot on one side only (not visible here) so the lever can only installed in the correct position. It may be that this is a 'steel-rubber-steel' sandwich so there may be the risk of twisting the upper part of the lever relative to the lower part if you apply too much force to the knob nuts:

The retaining plate DAM2576 for the above lever:

Gear-lever sub-harness with bullets to connect to the gearbox harness and 'sleeve' connections to the switch. Switch 520999a is also available: (ANG)

A good indication of why the OD circuit especially for this manual switch should be fused - single-insulated wires passing through earthed metal components - given the number of complaints of these knobs wobbling on the lever. This user has added heat-shrink over the lower part of the connectors: (MikeC73)

77 and later housing with single locating pin (A). Also showing the damper (B) and bush (C). In this case the gear lever could be fitted and removed with the bush already in the gearbox shaft: (Bill Etter)
