c. Refill Transmission. Refer to Table 2–6 for fluid refill quantities. The amount of refill fluid is less than the amount used for the initial fill. Fluid remains in the external circuits and transmission cavities after draining the transmission. After refill, check the fluid level using the procedure described in 2–4. TRANSMISSION FLUID CHECK. NOTE: Quantities listed are approximations and do not include external lines and cooler hose. Table 2–6. Transmission Fluid Capacity Sump

2–10. BREATHER a. Location and Purpose. The breather is located on top of transmission converter housing. The breather prevents air pressure buildup within the transmission and its passage must be kept clean and open. b. Maintenance. The amount of dust and dirt encountered will determine the frequency of breather cleaning. Use care when cleaning the transmission. CAUTION: When cleaning the transmission, do not spray steam, water, or cleaning solution directly at the electrical connectors. Spraying steam, water, or cleaning solution at the electrical connectors can cause codes and cross talk. CAUTION: When cleaning the transmission, do not spray steam, water, or cleaning solution directly at the breather. Spraying steam, water, or cleaning solution at the breather can force water or cleaning solution into the transmission and contaminate the transmission fluid. NOTE: Fluid loss out of the breather in cold ambient conditions during engine start may be remedied by venting the fill tube (refer to SIL 6­1k2k­06).
