AUTOMATIC TRANSMISSION SOFTWARE
Dinan Transmission software
comes in three different versions for the 1999-2003. The 1st version if designed for Stage 1-3 engine software and the 2nd version if for Stage 4-5 engine software and finally the 3rd stage if for the
Supercharger. It is very important your Dinan dealership verify the correct version is installed to match your current Stage of engine software.
Dinan Automatic Transmission Software
raises the shift points to a higher rpm for faster acceleration in both the "Sport" and "Economy" modes, allowing you to carry more road speed in each gear.
The software also provides firmer
and quicker shifting, further improving acceleration. Shift pressures are increased by up to 25% depending upon how the car is being driven (light loads vs. high loads). The increased pressures provide for more rapid
shifting, resulting in faster acceleration. The transmission software will typically shave 0.1 seconds off of 0-60 mph times and 0.3 seconds to 100 mph. The software provides the same benefits in both the automatic and
manual shifting modes.
The transmission software also provides the driver with Dinan's version of a "manual mode". The stock manual mode programming has been designed to upshift into a higher gear whenever
the normal shift point is reached, even when the manual mode has been selected. The stock program will also allow the car to downshift automatically in the manual mode whenever the vehicle's speed drops below 25 mph in
fifth gear or 15 mph in fourth gear. The Dinan program eliminates the automatic upshifts and downshifts unless the driver activates the accelerator "kickdown" switch intentionally. This allows the driver
complete control of gear selection and shift points whenever the manual mode is selected. As an added convenience, the Dinan software will return the transmission to first gear from any other gear whenever the vehicle
is brought to a complete stop.
I found this to be the case, however, when the vehicle is going less then 5 mph and in the sport 2nd gear possition the transmission will return to 1st gear.
