Disconnecting the cable from the tranny and hooking it to a drill it seems to work fine. It just dawned on me that the TF rotates counterclockwise. Does anyone know whether the Camaro drive gear is clockwise rotation or counterclockwise? Can I tell looking at it? If it is, will I need an adapter? | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | everything turns the same way, if the speedo seems to work, disconnect the cable at the head and drive the truck to see if maybe the cable is not turning, either bad cable or trans drive gear

Gear looks good and cable is new and operates the speedo from the transmission end when hooked to my drill. What holds the gear in the housing of the speedometer drive? It appears that there is a groove cut inside the housing, possibly for an o-ring. Am I missing that? | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | yes there should be a seal for a press fit, and if I recall right, there's a small metal plate held by 1 bolt that clamps the cable collar down ... might have a problem with the internal part that drives the speedo gear?

The gear on the shaft may have walked away from the opening. There is a clip in the shaft that holds it in place. If it,s ok see if the teeth are wallered down in the center.
They say money can't buy happiness. It can buy old Chevy trucks though.

My old gear was toast. The shaft was worn to half its original diameter next to the gear. Tranny guy theorized it allowed enough play for the gear to not mesh with the one inside the tranny. Will put it all together this evening and let you know. | | |
