OIL PRESSURE READINGS – Continued
8. While operating transmission during warm--up period, inspect transmission thoroughly for evidence of oil leakage
at all split lines and around all plugs and bolts. If leakage is present, check plugs and bolts for tightness. If
leakage continues, replace gaskets where required. Leakage of oil, in many cases, can cause faulty operation of
transmission.
9. Illustration in this work package shows oil pressure checkpoints, breather, manifold vacuum connections and oil
cooler connections. Pressure gauges used during tests should be connected as follows:
a Gauge 0.0 to 60 psi – Check points 6 and 8.
b Gauge 0.0 to 120 psi – Check point 4.
c Gauge 0.0 to 200 psi – Check points 3, 5, 15, and 16.
d Gauge 0.0 to 400 psi – Check points 9, 10, 11, 12, 13, and 14.
NOTE
Gauge 0.0 to 200 psi may be installed at checkpoints 10 or 12. Gauge 0.0 to 300 psi may be
installed at checkpoints 3, 4, 5, 6, 8, 10, 12, 15, and 16.
