3.3.5 Closed TV stop. With the TV fully closed, the TV lever shall be between 30.5 and
31.5 degrees from the detent position (see 4.3.4).
3.3.6 Automatic range upshifts input speed limits (through detent). The transmission
shall not automatically upshift at input speeds less than 3700 rpm with the TV lever at full-on
position and with the range selector in 1-3 position (see 4.3.5).
3.3.7 Drive range automatic downshift. The transmission shall produce an automatic
2-1 downshift between 775 and 985 rpm output speed (see 4.3.6).
3.3.8 Drive range converter stall capacity. With the output shaft stalled by the
dynamometer and with the range selector lever in the 1-3 range position and with TV lever in the
full-on position, the converter input stall speed and output torque shall conform to the
requirements of table III. Cooler oil flow shall be 7.5 gallons per minute (gal/min) (see 4.3.7).

3.4 Support and ownership requirements. The assembly shall possess the following life
cycle ownership characteristics (see 4.4).
3.4.1 Reliability. The transmission shall require no repair or maintenance, other than oil
and oil filter changes and oil additions, during 5000 miles of normal vehicle operation (see 4.4.1).
3.4.2 Leakage. During any evaluation sequence or at completion of all evaluations,
transmission leakage shall be limited to weep or seep (see 4.4.2 and 6.3).
3.4.3 Submersion. The transmission, pressurized internally with 3 to 7 psi air, shall show
no evidence of leakage when immersed in a water bath (see 4.4.3).
