Adhesives, solvents, and sealing compounds can burn easily, can give off harmful vapors, and are

harmful to skin and clothing. To avoid injury or death, keep away from open fire and use in well-ventilated

area. If adhesives, solvent, or sealing compound gets on skin or clothing, wash immediately with soap and

water.

Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or oil with rags.

Due to limited work area, be prepared with

suitable container to catch approximately one

quart of oil when removing lube oil pressure

port plug, or hose for pressure gage, from

underside of torque converter housing,

personnel can become wet with oil.

NOTE

Use a drain pan to catch leaking hydraulic oil.

PRESSURE TEST

(1) Remove plug from lube pressure port

of converter housing.

(2) Install 1/8 in. NPT adapter from

pressure test kit.

(3) Install 6 ft. (1.8 m) hose from kit on

adapter and 0 to 160 psi (1103 kPa)

gage on hose. Extend gage out from

under truck.

(4) Start engine (TM 9-2320-364-10).

Operate at approximately 1400 RPM

while assistant reads pressure gage.

(a) If lubrication pressure is not

between 40 to 45 psi (276 to 310

kPa), perform Steps (5)

through (7) below and go to

Step 3 of this Fault.

(b) If lubrication pressure is OK,

perform Steps (5) through (7)

below and replace transmission

(Para 3-4).

(5) Turn OFF engine switch.

(6) Remove pressure gage, hose, and

adapter from lube port of

converter housing.

(7) Apply thread sealing compound and

install plug in lubrication port of

converter housing. Tighten plug

to 48 to 60 lb-in (5.4 to 6.8 N.m).
