Symptoms of Failure

• Transmission oil leaks at the housing seam: When the loose parts in this kit degrade, the seal between the 4661101033: HOUSING and the main case can fail, causing external fluid seepage.
• Intermittent gear slipping under load: Worn cylindrical pins or fasteners allow the valve body to shift slightly, disrupting clutch pack engagement pressure.
• Abnormal driveline vibration or rattle: Missing or loose 0631306174: CYLINDRICAL PIN components create play between the pump housing and the converter bell housing.
• Erratic shift timing or harsh engagement: Degraded hardware in the 4661301096: HOUSING assembly can misalign the shift valve bores, causing delayed or harsh shifts.
