F3.5.2 Drill a 3.25 mm diameter hole (Number 30 drill) in the torque converter. Add a minimum of 500 mL of solvent neutral base oil to the torque converter.
42、Drain the converter for a minimum of 30 minutes. Coat a 3.18 mm closed-end pop rivet or 3.175 mm (1/8 in), pipe plug with a sealing compound (Gasket Sealing Compound, GM CCA Part Number 1050026 or equivalent).

44、 Stoddard solvent before test. F4.2 Clean heat exchanger (oil and water side). After cleaning, flush oil side of heat exchanger with Stoddard solvent and air blow dry. F4.3 Transmission Installation. F4.3.1 Measure flex-plate warpage by first mounting a dial indicator to the test stand. Place the po
45、inter of the dial indicator on one of the flex-plate bolt pads. This pad is the reference pad. Set the dial indicator to read zero. The flex-plate is turned so that the dial indicator meets one of the other pads in approximately the same area of the pad as that of the reference pad. Measure the thir
46、d pad similarly. The maximum allowable deviation from the reference pad is 0.25 mm. F4.3.2 Mark the torque converter bolt pads 1, 2, and 3. Mark the flex-plate pads 1, 2, and 3. Bolt the torque converter to the flex-plate so that the numbers on the torque converter and the flex-plate correspond. Mou
47、nt a dial indicator to the test stand placing the pointer on the converter hub to measure converter hub run-out. Set the indicator dial to read zero. Turn the converter and record the total indicator reading. Do this for all three converter bolt pad to flex-plate pad combinations. The maximum allowa
48、ble converter hub run-out is 0.25 mm. Choose the torque converter orientation that has the least run-out. If none of the orientations provide the required run-out, choose another converter and begin F4.3.2 again. F4.3.3 Install transmission on test stand with converter and flex-plate mounted as stated in F4.3.2. F4.3.4 Install TV cable, adjust as specified in Chevrolet Service Manual. F4.3.5 Calibrate all transducers, torque meter, thermocouples, and temperature readouts. F4.4 Fluid Level, Test Warmup, and Air Leak Check. F4.4.1 Fill transmission with 8 L of flui
