Test Pressure TA 2 773

This document is a technical analysis report that details the results of a performance test on a transmission. It measures various pressure specifications for components like the gear pump, torque converter, relief valve, and clutches. The test procedure involves disconnecting solenoids, manually shifting through gears, and measuring pressures at different engine speeds and transmission positions to check for proper operation. Any pressures outside the specified ranges would indicate issues that require further investigation.
