terms of performance and durability for an automatic transmission, the most
important improvement that can be made is to re-program the Control Assemblies.
These assemblies regulate the functions of the entire transmission; 95% of shift
performance comes from programming. Installing a Trans-Go Re-programming
Kit will instantly improve the whole personality of your GM, FORD CHRYSLER and
programming achieves comfort.
automatic transmissions coming off the assembly lines in Detroit and Japan are
truly masterpieces of engineering. But engineers have been asked to program the
shifting for smoothness and comfort. Also, consumer attitude surveys show that
drivers believe a soft, smooth shift is easier on the transmission. Actually,
just the reverse is true.
To add comfort, Automotive
designers have had to subtract a considerable amount of efficiency and
durability. They have achieved comfort by extending the time duration of every
shift. Not only does power slip away during this extended shift, but all
friction surfaces receive excessive wear because they are asked to work
stock automatic takes longer to complete each shift. Points A
to B, Figure 1 show only mild acceleration. During this period only a partial
power condition exists because the friction elements are slipping.
This extended slipping time prevents the
inertial energy from being efficiently utilized. It is lost in the form of heat
on the clutches and bands, instead of being utilized for forward motion.
Continually operating a stock automatic at full throttle will cause early
friction element failure.
To get high performance and improved
durability in an automatic, we must improve the way it executes every shift.
re-programming achieves durability and performance.
if you are willing to accept a faster shift, which will subtract some comfort,
you can restore full performance and durability. This is
exactly what a Trans-Go Re-Programming Kit does for you. It makes each shift
faster and more efficient. As a result, durability of the transmission
is immediately doubled.
Goal:Make the shift faster
without losing precision.
problem now becomes clear that what we need is re-programming that will
precisely control the complicated chain of events that occur during every shift
and do it in a far briefer span of time.
This is exactly what Trans-Go has accomplished.
Trans-Go kits cut slipping time by more than 70% (even more in the Competition
version) and at the same time improve the quality of the shifting action
itself. Figs 1 and 2 show the results.
automatic with a re-programming kit installed now shifts fast enough to take
advantage of inertial energy from rotating mass, including the inertial energy
from the transmission itself. Notice also the higher speed recorded (C) as the
curve leaves the chart. In driving this conversion at full throttle a sudden

the elapsed time of shifting is decreased, the life of the transmission
friction materials is increased.
Installing a Trans-Go Re-Programming kit will
at least double the life of the friction materials in the transmission. In many
heavy duty applications, a Trans-Go kit has made the difference between a few
months service without repair and several years.
The shorter shift time allows the friction
elements and gears far less time to wear themselves
out. The useful life of the friction elements in a transmission is directly
related to the amount of slipping that is allowed to occur during shifts.
Slipping converts useful energy to heat on
the surface of the clutches and bands. This heat transforms the friction
material to ash, which polishes its mating element, causing further slipping,
heat and deterioration of the friction elements.
The gears receive less wear, too. A slow
shift causes them to be partially engaged for a longer period during the gear
changing process, resulting in unnecessary heat, wear and power loss.
QUICK SHIFTS ALL THAT MATTER?
by a long way. We have seen what can be gained in durability and
performance with quicker shifts. Overlap is also extremely important. Overlap
is a condition caused by applying a gear before the previous gear has been

is done purely for smoothness. Overlap causes delayed shifts. Overlap is the
main cause of shift delay, or hesitation when shifting manually.
Excessive Overlap is eliminated with Trans-Go
Re-Programming. The difference is felt immediately and there are substantial
increases in performance, durability and fuel economy.
