Take your DMM, set it to measure Ohms (use the 20k setting.) Measure the resistance across the pellet of the ignition key. Place one probe on the silver part of one side of the pellet, and the other probe on the other side. Write this value down. 2. Purchase a resistor or resistors that add up to the value measured in step 1. Radio Shack is a great place to go for the resistors, heat shrink tubing, and the “bullet-style” solderless connectors. 3. Take the 16 ga. wire and cut into 2 four-inch pieces. 4. Strip off approx 1/16″ of insulation off each side of both wire pieces. 5. Put your resistors together in series (or if you’re lucky and have a chip that has a resistance that matches a single resistor) and solder one wire to one end of the resistor(s) and the other wire to the other side. Example: You measure 11.72 on the 20k (k meaning kilo or 1,000) scale. The closest match is 11.801 which is a #15 “chip.” Always remember that resistors have a tolerance of 2%, meaning the resistance value of the “pellet” can be either 2% higher or 2% lower than 11.801 k ohms (11.72 falls in tolerance range.) You will want to aim for 11,801 ohms. So when you go to Radio Shack you want to pick up a 10,000 ohm (10k,) a 1,000 ohm (1k,) and an 800 ohm resistors to wire together in series to achieve the 11.801k ohm value.

Correction 1. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: 2. Set the tire pressure to 30 psi (205 kPa) COLD. Subject: Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) Models: 1998-2005 Buick Park Avenue, Park Avenue Ultra 2000-2005 Buick LeSabre 1998-2004 Cadillac Seville (SLS, STS) 2000-2005 Cadillac DeVille (DTS only) 2001-2003 Oldsmobile Aurora 2000-2005 Pontiac Bonneville (17″ Tires only) • Missing balance weights • Bent rim flange • Irregular tire wear • Incomplete bead seating • Tire irregularities • Mud/ice build-up in wheel • Stones in the tire tread © 2009 General Motors Corporation. All rights reserved 3. Road test the vehicle with the Electronic Vibration Analyzer (EVA) essential tool for a sufficient distance on a known, smooth road surface to duplicate the condition. Record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 10 miles (16 km) at 45 mph (72 km/h) or greater, in order to eliminate any possible tire flat-spotting. 4. If the road test indicates a shake/vibration still exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer. If any assembly calls for more than ¼ ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. Important: Some GM dealers may have a Hunter GSP9700 Road Force Balancer, or a Coats XR1850 Runout Balancer. Either will simplify Step 5 by not requiring dial indicators. If a Hunter GSP9700 machine is available, it may also be used to measure the radial force of the tire/wheel assembly. A guideline here is 18 lbs or less. 5. While on the balancer, measure wheel runout. If radial or lateral runout exceeds .020 in (0.50 mm) for aluminum wheels (.030 in (0.76 mm) for steel wheels), replace the wheel. 6. After confirming wheel balance and wheel runout, if any changes were made, road test the vehicle again. 7. If the smooth road shake/vibration still exists: Important: THE CONTROL ARMS SHOULD ONLY BE INSTALLED ON VEHICLES IF, AFTER THE TIRE AND WHEEL DIAGNOSIS AND REPAIRS HAVE BEEN PERFORMED, THE VIBRATION CONDITION STILL EXISTS. 8. Replace both lower control arms on vehicles built prior to the following VIN breakpoints. On Aurora, Bonneville, DeVille, Park Avenue, Park Avenue Ultra and Seville models, a newly developed hydro-bushing lower control arm with improved damping characteristics has been released. This control arm is not used on the LeSabre. The new lower control arms may provide an incremental improvement to the vehicle ride. Customers who have become “tuned in” to the shake condition may still feel some shake in the vehicle after the new lower control arms are installed. Refer to Lower Control Arm Replacement in SI (refer to the Parts Information table below for SI document ID numbers) . Important: The completed worksheet must be attached to the hard copy of the repair order. • If a Hunter GSP9700 Road Force/Balancing machine is used, record radial force variation (RFV) on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies read more than 18 lbs, match mount the tire to the wheel to get below 18 lbs. Readings of 12 lbs or less are preferable for sensitive customers. • If a Coats XR1850 Runout/Balancing Machine is used, record radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than .040, match mount the tire to the wheel to get below .040. Readings of .030 inch or less are preferable for sensitive customers. • If the RFV or runout cannot be reduced to an acceptable level, replace the affected tire(s) under the guidelines of the GM Tire Warranty. • The screened tire program is only available for the General branded tires used on the Buick LeSabre. Complete the tire request form at the end of this bulletin and fax to Continental/General. • Road test the vehicle to ensure the shake/vibration has been eliminated

TOYOTA G52, G54, W56 & G58 (AX5) 5 SPEED TRANS. TO CHEVY AND BUICK ENGINES INSTALLATION INSTRUCTIONS:

This bellhousing is not compatible with transmissions that were previously equipped with diesel engines. The bellhousing design incorporates a special modified clutch release lever and a Toyota Land Cruiser slave cylinder. We have provided slave cylinder mounting on the passenger side of the bellhousing and have incorporated a new push rod location that will provide a quick short travel of the clutch release mechanism. The kit does not include the Toyota Land Cruiser slave cylinder, Part No. 31470-60022. The bellhousing is designed for the 153 tooth flywheel application. If your block is equipped with a 168 tooth flywheel, you will be required to use a high torque starter without a nose cone to fit the bellhousing (P/N 22-0001). The bellhousing is compatible with the Buick flywheel that has 160 teeth. A slight modification may be required in the starter pocket area when using the Buick installation. The inside of the bellhousing uses a high profile Centerforce diaphragm clutch assembly. By using this pressure plate, you can be sure that the slave cylinder travel will be appropriate for obtaining a maximum clutch release. The release bearing, Part No. N1430, is a standard flat faced Chevy release bearing. The bearing must not have continual contact with the fingers of the clutch. Adjust the length of your push rod for clearance between the fingers and the face of bearing. In order to adjust the height of the release bearing, we recommend that you install the new bellhousing over the clutch assembly and onto the engine prior to assembling the transmission to the bellhousing. By doing this procedure, you will be able to install the clutch release lever, slave cylinder, slave cylinder push rod, and release bearing directly to the clutch assembly. The reason this is necessary is that there are variations as to the thickness of the flywheel which either raise or lower the fingers of the clutch as related to the release bearing. The push rod of the slave cylinder can be adjusted, to obtain the necessary clearance between the release bearing and clutch fingers. If the bearing is permitted continual contact on the fingers, then you will have premature release bearing failure. We do not furnish a rubber boot for the area between the bellhousing and clutch arm since it is too restrictive for the clutch arm movement. We believe that the location of the opening is such that any dust or other debris will have a hard time accessing the opening. If you anticipate water hazards, we would recommend a small rubber flapper that could be screwed to the outside of the bellhousing.
