MIL-DTL-62099D(AT)
4.3 Operating requirements verification.
4.3.1 Warm-up check. To determine conformance to 3.3.2, with the transmission filled
with lubricant (see 4.2.2.1), the following test shall be performed:
a. Place the range selector lever in the reverse range gear shift position with the
transmission TV lever in the full-on position and the output shaft stalled.
b. Increase input speed to 1000 + 50 rpm and run at this speed until oil pressures
stabilize.
c. Release the output load on dynamometer, increase the input speed to
2200 + 20 rpm, and run until all air is evacuated from the converter cooler circuit
and sump oil temperatures are stabilized.
d. Note reverse function (output rotation opposite input rotation).
4.3.2 Functional pressure and flow test. To determine conformance to 3.3.3, the
following test shall be performed:
a. Place the range selector shift lever in the reverse position with the TV lever in the
"full-on" position and no dynamometer load on the output shaft.
b. Increase the input speed to 2200 rpm.
c. Determine main oil pressure.
d. Reduce input speed to 1000 rpm.
e. Place the range selector shift lever in the "1-3" range position and the TV lever in
a "full-on" position with no dynamometer load on the output shaft.
f. Increase the input speed to 3000 + 20 rpm.
g. Determine the lockup clutch apply pressure, cooler out oil pressure, and cooler oil
flow.
4.3.3 Automatic shift test. To determine conformance to 3.3.4, the following test shall be
performed:
a. Place the range selector shift lever in the "l-3" range position and the TV lever in a
"partial-on" position.
b. Increase the input speed as required to obtain the automatic "1-2" and "2-3" range
upshifts.
c. By adjustment of the TV lever during "2-3" and "3-2" cycle shifts establish the TV
lever position that produces a "2-3" range automatic upshift. This position is
defined to be the "at detent" position for the TV lever.
d. Place a light dynamometer load on the output shaft with the TV lever at the "at
detent" position.
e. With the range shift selector lever in the proper range position and with full engine
throttle, adjust the output load to obtain all automatic shift points.
f. Determine the input speed at which each automatic upshift occurs.
