Symptoms of Failure

• Transmission oil seepage at the mid-case joint: When the loose parts in this kit fatigue or corrode, the seal between the front and rear housing sections can fail, leading to visible oil leaks around the transmission belly.
• Abnormal gear engagement noise or vibration: Worn or missing fasteners from the 4657.183.326 set can allow micro-movement between the TRANSMISSION HOUSING and the rear section, causing misalignment and harsh shifting.
• Loose or rattling housing sections during operation: A telltale sign of degraded loose parts is a metallic rattle from the transmission casing, especially under load or during deceleration.
• Difficulty maintaining hydraulic pressure: Structural play from a compromised housing joint can disrupt internal oil galleries, leading to slipping clutches or delayed engagement.
