The T310 unit a range - shifted transmission which has forward speeds. This transmission features a and auxiliary compound section controlled air shift range selector located the shift lever . The compound section equipped with a synchronizer facilitate - /HI - range shifting.

The range provides five low

Never attempt move the vehicle from a stopped position any gear higher than fourth speed gear Depending road may necessary start third fourth speed range there are five forward gears that can shifted the standard manner Always remember , however , double clutch whether moving down through these Reverse gear can used range only

Upshift - With the shift lever

NEUTRAL, flip the air shift range selector down range. Then shift the transmission into first gear . Shift second, third, fourth and fifth speed gears, double clutching between the gears. When maximum engine RPM has been reached fifth gear , flip the air shift range selector range (preselect). Then move the shift lever through NEUTRAL sixth gear . the shift lever passes through NEUTRAL, the transmission placed into range. Continue following the normal sequence - 8 - 910), being sure double clutch from one gear the next.

Downshift Shift from 10th speed gear down through the range - 8 - 76), double clutching through each gear While still sixth speed gear , flip the air shift range selector down range Then move the shift lever through NEUTRAL fifth speed gear the shift lever passes through the transmission placed into shift down second and first speed double clutching between all

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 gears. For normal highway use, start range, first gear and shift through second, third and fourth. The - and positions range for this transmission are designed for use f - highway and slow - moving operations such curb pouring, material spreading, heavy load/steep grade. REVERSE used range for four reverse speeds.

Upshift — Begin first gear (shown 1/5 shift pattern diagram) with air - shift selector Upshift second gear (2/6 shift pattern diagram) range the normal manner (double - When ready upshift 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 When maximum engine RPM has been reached fourth gear , flip the air - shift selector range then double - clutch and shift fifth gear the shift lever passes through will put the transmission Continue upshift through normal seventh and eighth while double -

Downshift — Downshift normal from eighth seventh, sixth and fifth range (double - clutching between all gears). The next lower shift will fourth gear range. While still fifth gear , flip the air - shift selector range (preselect), then double - clutch and move the shift lever through NEUTRAL fourth gear . The move through NEUTRAL activates the air - shift mechanism, this time range. The next lower gear third gear range. Double - clutch down through the remaining gears first gear range needed.
