ROADMASTER

Here are some pictures of the console and interior I installed from a '94 Olds LSS into my '93 Buick Roadmaster Wagon. Click on the pictures for a full size version.

 

     

 

The parts required from GM are all from a '96 Impala SS. Once I find my receipt, I'll fill in the prices:

  • 12559026    Shifter Cable

  • 12553291    Shifter Lever

  • ????????      Cable Transmission Mount.

The shifter bolted in quite easily. There is a small hump on the floor that seemed to be perfectly placed for mounting. I drilled two holes and used the original tapered bolts from the donor car which seemed to self-thread the holes and holds it securely. I drilled one hole in the floor at the front of the console, near where the cable went through the floor. This area did not self-tap very well and so it has a nut on the underside.

 

     

 

Once the shifter location was determined, choices as to where to drill the cable hole were limited as the bracket holds it at an obvious angle to the floor. It was hard to determine exactly where the cable would protrude relative to the transmission, but it appeared there was room. I used a 2" hole saw, but would recommend a size smaller as the shifter grommet was not as tight a seal as I would prefer. Once drilled, the tailshaft was a bunch closer than I had hoped, but with a 2" hole in the floor I was committed. To prevent chafing, I wrapped the cable with some 3/8" rubber hose.

 

     

 

Installing the cable was easy. All that was required to install the cable mount was undo two transmission pan bolts and bolt it in. The shifter cable "snaps" in place at both ends. To adjust the console to the transmission, put the shifter in neutral, put the transmission in neutral, adjust the cable to where you want it and snap the adjuster clip in place on the transmission (which looks like an oversized fuel filter C-clip). Presto!

 

It was important for me to have all the safety features work such as the ignition switch on-off shift lock, neutral/park safety switch and the reverse lights. I was disappointed to learn that most of these are located on the column and the SS had them incorporated into their shifter. I didn't think I could get this resolved easily... but never underestimate the power of the IGBA discussion group. Kenneth Rolt put me in touch with Dave Macdonald who had put an aftermarket shift in his car. He had the same safety concerns and resolved it by having both the console shifter and the column shifter linkages hooked up together. The console shifter moves the column, making all the features work. The trick is that once the column shift lever is removed, it moves freely! Who knew?!?

 

The console's two cigarette lighters and shifter lights were easily hooked up. I tapped into the existing lighter and used the ashtray light as my dimmer source for the indicator lighting. It was fairly straight forward, even the wire colors were the same. The only modification I had to make was to cut a semi-circle out of the front of the console for the wires.

 

Total installation time was about 4 hours, but a lot of that was double and triple checking that I wasn't going to drill or cut through something critical. If I was to do it a second time, it would probably only take an hour and a half.

 

It seems to work great. The leverage ratios must be standardized by GM because the transmission, the console indicator, and the dash indicator all line up perfectly from "P" to "1".
