1. Watch where you're standing while diagnosing a transmission problem. Some of the procedures in this program are designed to force the transmission into gear. This can cause the vehicle to lurch forward or backward suddenly, and without warning.

2. Always wear the proper protective eyewear and clothing before working on any component containing transmission fluid. Remember, transmission fluids can reach temperatures in excess of 350º F - at that temperature, transmission fluid would quickly remove skin and cause serious injury.

3. Always wear work gloves whenever you're working with transmission cases. The cast edges are sharp, and can cause serious cuts.

4. Always stay clear of the belts and fan blade, and be careful revving the engine on a car with a flex fan - damaged blades have been known to come flying off without warning.

5. Always provide plenty of ventilation when running a vehicle in the shop.

6. Be very careful probing any wiring on vehicles with supplemental inflatable restraints (airbags). Touching the wrong wire can activate the airbag - even with the battery disconnected. Check your shop manual for the procedure for disabling the airbag before performing any electrical diagnostic procedures.

7. Microprocessors and computers are susceptible to damage from electrostatic discharge. Always use a static strap when working with these components, and always take the necessary precautions to prevent damage to electronic components.

8. Never disconnect any computer circuit with the key on or the engine running, unless specifically told to do so.

9. Always have a dry chemical fire extinguisher on hand when working on any electrical system.
