Caution

Make sur e air essur e least psi and unit operating temperatur e befor e making range shifts. Always start This also applies dynamometer testing. When the truck stationary , NOT shift into range and then start moving the damage the synchr onizer may r esult.

The T310M a range - shifted transmission which has forward speeds. There a and auxiliary compound section controlled air - shift selector the shifter . This compound section equipped with a synchronizer facilitate - range shifting. The T310M transmission also provides a multi - speed reverse feature means reverse gearing the compound case which works conjunction withLO, first and second speed gears the main box. The air - shift selector must moved the R (REVERSE) position order utilize the multi - speed reverse feature.

range provides six low ratios for six forward gears the range provides four additional forward gears which can shifted the standard manner Remember , however , double - clutch when moving down through the For normal highway start first gear and shift through third and The - and positions range for this transmission are designed for use f - highway and slow - moving operations such curb material heavy load/steep REVERSE used range for four reverse https://www.truck-manuals.net/mack/

Upshift — Begin first gear (shown 1/5 shift pattern diagram) with air - shift selector range. Upshift second gear (2/6 shift pattern diagram) range the normal manner (doubleclutching). When ready upshift again, depress the clutch pedal and release the accelerator pedal the normal manner . Repeat this shifting pattern through the remaining gears fourth speed (4/8 shift pattern diagram). When maximum engine RPM has been reached fourth gear , flip the air - shift selector range (preselect), then double - clutch and shift fifth gear . the shift lever passes through NEUTRAL, will put the transmission range. Continue upshift through normal sixth, seventh and eighth gears, while doubleclutching.

Downshift Downshift normal from eighth sixth and fifth range (double - clutching between all The next lower shift will fourth gear While still fifth gear , flip the air - shift selector range then double - clutch and move the shift lever through NEUTRAL fourth gear The move through NEUTRAL activates the air - shift this time The next lower gear third gear

Double - clutch down through the remaining gears first gear range
