4.2 Verification methods. The types of verification methods included in this section are
visual, inspection, measurement, sample tests full scale demonstration test, or equivalent tests,
simulation modeling, engineering evaluation, component properties analysis, and similarity to
previously-approved or previously-qualified designs.
4.2.1 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 contractor for alternatives that
replace verifications required by this specification.
4.2.2 Test conditions. The transmission shall be installed on an absorption dynamometer
test stand with provisions for connecting the drive cover studs to an input power supply, linkage
controls, and external hydraulic system. The engine used for input power supply shall be the same
type as used in vehicle installation or a suitable equivalent power source. Separate linkage
controls shall be provided for the engine throttle, transmission TV lever, and range selector shift
lever. The external hydraulic circuit, which includes all oil lines, oil filter, and flowmeter, shall
have a pressure drop between the transmission to oil cooler "outlet" connection point and the oil
cooler to transmission "inlet" connection point that is in accordance with figure 1. Tests shall be
made at ambient room temperatures and oil level shall be in accordance with 4.2.2.1.
4.2.2.1 Transmission oil level. The design oil level shall be determined using one of the
following options:
a. Option I. When testing with the sump oil pan installed, fill the transmission with
approximately twenty (20) quarts of oil. The oil level shall be at the "Full" mark
on the dipstick, as the installation drawing (see 2.2.2) directs, while running in
neutral range at 1500 rpm input speed, with output shaft stalled, and with the oil at
