(3) In fourth gear, pivot right steer, the

except that the actions described in (1) and (2), above,

take place in opposite sides of the transmission. (The

the steer clutch is engaged. The power flow in the left

output clutch drives the left output, while the steer clutch

output section is therefore, the same as that described

drives the right output. Thus, the right output is slower,

and the vehicle steers toward the right.)
