Here's a general outline of the process. This is not a comprehensive guide, and you should consult a repair manual specific to your 1993 Pontiac Trans Am for detailed instructions and torque specifications. Improper torque can lead to premature failure.
Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the car from rolling.
* Torque wrench: Crucial for proper tightening of bolts.
* Sockets and wrenches: A variety of sizes will be needed, likely including metric.
* Pry bar or large screwdriver: To help separate the old mount from the transmission.
* Penetrating oil (like PB Blaster): To loosen rusted bolts.
* New transmission mount: Ensure you get the correct replacement part for your specific Trans Am.
* Possibly a transmission jack: While not strictly necessary, a transmission jack makes the job significantly easier and safer. If using one, you'll need to consult its instructions for use.
Steps (General Outline):
1. Safety First: Securely jack up the car and place it on jack stands. Engage the parking brake and use wheel chocks.
2. Access the Transmission Mount: The location varies slightly depending on the specific transmission (automatic or manual). You'll likely need to work from underneath the car. You may need to remove some heat shields or other components to get sufficient access. Consult your repair manual for precise locations.
3. Loosen the Bolts: Apply penetrating oil to the bolts holding the old transmission mount in place. Allow it to soak for a while before attempting to remove the bolts. Use the appropriate sockets and wrenches. Often, there are bolts attaching the mount to both the transmission and the vehicle's chassis.
4. Remove the Old Mount: Once the bolts are loose, carefully separate the old mount from the transmission and the chassis. A pry bar or large screwdriver might be helpful to gently leverage it free. Be prepared for the transmission to shift slightly as you do this. This is where a transmission jack becomes very helpful in supporting the transmission's weight.
5. Install the New Mount: Carefully align the new transmission mount with the transmission and the chassis. Install the bolts and tighten them hand-tight only for now.
6. Double Check Alignment: Ensure the mount is seated correctly and the transmission is properly aligned.
7. Tighten the Bolts: Use your torque wrench to tighten the bolts to the manufacturer's specified torque. This is critical to prevent premature failure. Refer to your repair manual for the correct torque specifications.
8. Lower the Car: Carefully lower the car using the jack.
9. Test Drive: After the repair, test drive the car to ensure the transmission mount has resolved the issue. Check for any vibrations or unusual noises.
Important Considerations:
* Repair Manual: This is crucial! A factory service manual specific to your 1993 Pontiac Trans Am will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Safety: This job involves working under a car. Never work under a car supported only by a jack. Always use jack stands and wheel chocks.
* Transmission Jack (Highly Recommended): A transmission jack makes this job significantly easier and safer by supporting the weight of the transmission.
If you are not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic. Improperly installing a transmission mount can lead to further damage to your vehicle.
