MIL-DTL-62461E(AT)
4.1.2 Conformance inspection. Unless otherwise specified (see 6.2 and 6.4), each
transmission shall be tested in accordance with the 100% CI verifications as specified in table III.
As specified in the contractual sampling plan (see 6.2), select transmissions shall complete and
pass the tests as specified in 4.4.1, 4.4.4.2, and 4.4.4.3.
4.2 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be
conducted under the following conditions:
a. Air temperature: 73 ± 18°F (23 ± 8°C).
b. Barometric pressure: 28.5 (+2, -3) inches mercury (in. Hg)
(725 (+50, -75) millimeters Hg)
c. Relative humidity: 50 ± 30%.
4.3 Verification methods. The types of verification methods included in this section are
visual, measurement, sample tests, full-scale demonstration tests, simulation, modeling,
engineering evaluation, component properties analysis, and similarity to previously-approved or
previously-qualified designs.
4.3.1 Verification alternatives. The manufacturer may propose alternative test methods,
techniques, or equipment, including the application of statistical process control, tool control, or
cost-effective sampling procedures, to verify performance. See the contract for alternatives that
replace verifications required by this specification.
4.4 Order of inspection. The following tests shall be in any order except that the seals
verification (see 4.3.3.3) shall be performed at the conclusion of each test.
4.4.1 Design and construction verifications. Use one or more of the methods outlined in
4.3 to verify the following.
a. That the transmission, operating with a single stage three element integral torque
converter, is built in accordance Drawing 12331877, and the control valves are
accordance with Drawing 13214E2449.
b. That the transmission is designed to accept input power from a diesel engine
conforming to MIL-DTL-62462, and transmit power and torque commensurate
with its use on a vehicle conforming to MIL-V-62468.
c. That all accessories and equipment are installed on the transmission, properly
adjusted, and in accordance the applicable drawings as specified in (a).
d. That the dry weight of the transmission is not more than 1350 lb (612 kg), and the
weight with residual oil is not more than 1400 lb (635 kg).
4.4.2 Materials verification. Use one or more of the methods outlined in 4.3 to verify that
transmission is made with the material requirements as specified in applicable drawings
(see 4.4.1(a)), and does not contain asbestos, cadmium, or any other radioactive material.
