3. TECHNICAL INSPECTION NOTES

• Transmission Pan: Inspected for signs of damage or leakage. [Status: Pass]
• Mounts: Visual inspection of transmission mounts during service. [Status: Serviceable]
• Fluid Condition: Old fluid noted as [Dark/Red/Burnt]. Replaced with fresh fluid to ensure proper hydraulic pressure and cooling.

B (Braking): On Hybrid models, this maximizes regenerative engine braking to slow the car without overusing the physical brake pads. Transmission Pan: Inspected for signs of damage or leakage
