TORQUE CONVERTER LEAKAGE Possible sources of torque converter leakage are: • Torque converter weld leaks at the outside diame- • Torque converter impeller shell cracked adjacent Hub weld is inside and not visible. Do not attempt to repair. Replace torque converter. AIR PRESSURE TEST OF TRANSAXLE Fabricate equipment needed for test as shown in figures 6 and 7. The transaxle should be prepared for pressure test as follows after removal of the torque converter: (1) Install a dipstick bore plug and plug oil cooler line fitting (lower fitting). (2) With rotary motion, install converter hub seal cup over input shaft. It must go through the converter (3) Attach and clamp hose from nozzle of Tool C-4080 to the upper cooler line fitting position in case. CAUTION: Do not, under any circumstances, pressur- (4) Pressurize the transaxle using Tool C-4080 until the pressure gauge reads 8 psi.
