CHAP 5, SEC XXXIV TEST AND ADJUSTMENTS PAR 233 Figure 368. Transmission oil pressure check points and controls Figure 369. Checking transmission oil pressure (7) In tests for lockup release, first increase the input speed to above the Point where lockup occurs. Then slowly reduce the speed, while observing lockup clutch apply pressure, until lockup pres- sure drops quickly. At this moment, record governor pressure and input speed. (8) During all tests, when the output couplings at the right and left sides of the power train are disconnected from the output drive assemblies, observe the couplings to check their rotation. Rota- tion should be as outlined in f , below. f. Rotation of Power Train Outputs (1) In all forward and reverse gears, both the output couplings will tend to rotate even at engine idle speeds. A light application of the 198 Change 2
