The VSCF sight glass scale is color coded in green, red, and yellow.

 (a)  
The green range indicates that no servicing is required.

 (b)  
The red range indicates that servicing is required immediately.

 (c)  
The yellow range indicates that the oil level is acceptable but servicing is recommended at the earliest opportunity.

 

 (2)  
Leakage of the seal in the VSCF will let oil flow from the VSCF to the spline cavity. The input shaft seal can be defective if either of these indications occur after you fill the VSCF with oil:

 (a)  
The oil level in the VSCF decreases while the oil level in the spline cavity increases.

 (b)  
The oil level in the VSCF increases while the oil level in the spline cavity decreases.
