TM 10-3930-659-34 4-35. TRANSMISSION LUBE PRESSURE TEST. 4. Install    hose    (8)    and    pressure    gage    (9)    on adapter (5). 5. Start  forklift  truck  and  run  until  transmission  oil temperature    gage    indicates    that    transmission fluid is warm (see TM 10-3930-659-10). 6. Operate  engine  at  fast  engine  idle  speed  (see TM  10-3930-659-10)  and  note  pressure  reading on  pressure  gage  (9).  Pressure  must  read  3-15 psi  (21-103  kPa).  If  pressure  reading  is  within specification, go to step 12. 7. Check   for   pinched   or   blocked   hoses   between transmission   oil   cooler   (10)   and   transmission assembly (12). 8.
