The type 01M transmission fitted from January 1995 is very similar to the type 096 . . . but its performance is enhanced by a number of refinements.
The torque converter lock-up facility has been extended to all forward speeds, for greater fuel economy. The electronic control unit now incorporates "fuzzy logic", allowing infinitely variable gearchange points to be determined in response to driver demands and driving conditions, for maximum performance or economy, as appropriate. The "sport" and "economy" modes are determined by throttle position and its rate of change, as described above for the later 096 units. In this way, gearchanges can be economy-orientated, but full acceleration is always available on demand. A further refinement is the inclusion of a gearchange map for gradients, allowing the control unit to select the most appropriate ratio to match gradient to engine output when climbing hills and to allow adequate engine braking when descending.
