🔌 Function

Vents the transmission so pressure does not build as the oil warms.

⚠️ Common Signs of Failure

• Oil pushed out past the seals as pressure builds
• Breather blocked with oil mist residue or salt
• Oil weeping from the breather itself
• Casing pressurising in service

🛠️ Service Notes

• Ratio is the selection detail — this covers the 1.99:1 and 2.48:1 units
• A blocked breather pressurises the casing and pushes oil past the seals, so check it before chasing seal leaks
