TM 9-2320-303-10 5. TRANSMISSION. CAUTION Transmission must not be operated for extended periods of time until a Hot Check has verified proper fluid level.      Transmission   damage   can result  from  extended  operation  at improper fluid level conditions. COLD  OIL  CHECK  (COLD  RUN  BAND). Run  engine  for  one  minute  at  idle  speed. Idle engine in Neutral (N) until transmission reaches     60-120F     (16-49C).          Shift transmission   to   Drive   (D),   then   Reverse (R), then return to N.  Remove dipstick from oil   filler   tube,   wipe   clean,   and   check   oil level.    Oil  registering  in  the   COLD   RUN band indicates a sufficient quantity of oil to safely operate the transmission until temperature     reaches     160-200F     (71- 93C).  If fluid level is not within COLD RUN band,   add   or   drain   fluid,   as   required,   to bring     level     within     the     band.          When temperature     reaches     160-200F     (71- 93C), a hot oil check MUST be performed. HOT OIL CHECK (HOT RUN  BAND).    Be sure  temperature  has  reached  160-200F (71-93C).      With   truck   on   level   ground, engine  idling,  and  transmission  in  Neutral (N), remove dipstick from oil filler tube, wipe clean, and check oil level.  If oil registers in the   HOT   RUN   band,   quantity   of   oil   in transmission    is    safe    for    operating    the vehicle.      If   it   registers   on   or   below   the bottom line of the  HOT RUN band, add the required  amount  of  oil  to  bring  oil  level  to the middle of the  HOT RUN band. 6.
