Note
1. Remove the two oil cooler line hoses and apply air pressure of 196 kPa {2.0 kgf/cm2, 28 psi}
from the return hose (pipe) side.
Caution
2. If there is no air blown out the feed side, flush the oil cooler lines using the power-flushing tool. (See Power Flushing)
Recommended power-flushing manufacturer
3. If there is ventilation, carry out the following steps.
(1) Remove the oil pan and inspect the fluid filter element from the front filter.
(2) If the element is covered with too much debris or particles and cannot be seen, replace the oil cooler. (See OIL COOLER REMOVAL/INSTALLATION.) (See OIL COOLER DISASSEMBLY/ASSEMBLY.)
(3) If the element can be seen, flush the oil cooler lines using the power-flushing tool.

Power Flushing
Repair procedure
1. Before power flushing, inspect the hoses/lines and clamps. Power flushing must begin with back flushing followed by forward flushing to quickly dislodge the restriction. If back flushing is not performed before forward flushing, the restriction could further reduce the ATF flow through the internal mesh type baffle of the cooler and flushing will not be effective or possible.
Inspecting oil lines and clamps
1. Be sure to inspect the lines (hoses/pipes) for cuts, crimps (pinched), cracks or any other damage before reusing them.
Caution
Back flushing
1. Using the power flushing equipment manufacturer's instructions, connect equipment so the flushing fluid flows in the opposite direction of normal fluid flow.
2. Flush oil cooler/lines until discharge fluid is clean.
Caution
Forward flushing
1. Connect power flushing equipment so the flushing fluid flows in the direction of normal fluid flow.
2. Flush oil cooler/lines until discharge fluid is clean.
