The Hydra-Matic 3L30 transmission is a fully automatic unit
for rear wheel drive vehicles which provides three forward gear ranges and
a reverse.
The major components of this transmission are:
| • | Torque converter clutch assembly |
| • | Three multiple disc clutches |
The oil pressure and shift points are controlled by a vacuum modulator
that senses engine torque as a relation to engine vacuum.
You can operate the transmission in any one of the following six modes:
| • | P--Park position prevents the vehicle from rolling either
forward or backward. For safety reasons, use the parking brake in addition
to the park position. |
| • | R--Reverse allows the vehicle to be operated in a rearward
direction. |
| • | N--Neutral allows the engine to be started and operated without
driving the vehicle. If necessary, you may select this position in order to
restart the engine with the vehicle moving. |
| • | D--Drive position is used for normal driving conditions.
Drive position provides three gear ratios plus a converter clutch operation.
Downshifts are available for safe passing by depressing the accelerator. |
| • | 2--Manual second provides acceleration and engine braking.
You may select this range at any vehicle speed. |
| • | 1--Manual Low provides maximum engine braking.
You may select this range at any vehicle speed. |
