Problem:
The 9W-7189 Flow Control Valve was replaced by 142-2882 Flow Control Valve. This change could lead to vibration and noise in the transmission hoses due to unstable transmission pressures.
Failures of the 7T-8797 Spacer and/or the 8J-2283 Snap Ring used in modulating the relief valve of the transmission hydraulic control valve may also occur due to impact loads against the spacer.
Solution:
If a machine exhibits any of these conditions, perform the following:
- 1. Remove the 142-2882 Flow Control Valve.
- 2. Install a new 9W-7189 Flow Control Valve.
