What is the procedure for checking the oil pump volume in a Mopart automatic transmission?


a) Disconnect the return tube from the cooler and place a collection container underneath. Start the engine at moderate idle speed with the gear selector in Neutral. If the fluid flow is intermittent or takes more than 20 seconds to accumulate 950 ml (one quarter of a gallon) of ATF PLUS 3, disconnect the input tube to the cooler in the transmission. Refill the transmission to the correct level and recheck the pump volume. If the flow is within acceptable limits, replace the cooler. Then fill the transmission to the correct level with Mopart ATF PLUS 3 automatic transmission fluid (Type 7176). If the fluid flow is still incorrect, check the operating pressure using the Transmission Hydraulic Pressure Test procedure.
b) Disconnect the return tube from the cooler and place a collection container underneath. Start the engine at moderate idle speed with the gear selector in Drive. If the fluid flow is intermittent or takes more than 20 seconds to accumulate 950 ml (one quarter of a gallon) of ATF PLUS 3, disconnect the input tube to the cooler in the transmission. Refill the transmission to the correct level and recheck the pump volume. If the flow is within acceptable limits, replace the cooler.
