Re-Programming Shift Kits
Kits instantly re-program automatic transmissions for high performance and
Unique kits re-calibrate the transmission to shift far more
In 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 IMPORT transmissions.
Factory programming achieves comfort.
The 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 overtime.
The 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.
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.
Trans-Go re-programming achieves durability and performance.
So 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.
the shift faster without losing precision.
The 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.
The 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 forward lurch can be felt when it shifts, very similar to a

kits give you more complete gear control of your transmission. Most kits offer
Shift Command, a special feature of our re-programming that allows you to shift
back to low at any speed! Trans-Go kits also retain fully automatic shifting in
the "D" position.
As the elapsed time of shifting is decreased, the life of
the transmission friction materials is increased.
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

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.
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.
ARE QUICK SHIFTS ALL THAT MATTER?
Not 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 released.
Excessive overlap as seen in the Fig. 3 converts engine
horsepower into damaging heat and causes clutch wear, band wear, shift delays,
short oil life, and increased fuel usage.
Factory programming includes an excessive amount of overlap.
This is done purely for smoothness. Overlap causes delayed
shifts. Overlap is the main cause of shift delay, or hesitation when shifting
is eliminated with Trans-Go Re-Programming. The difference is felt immediately
and there are substantial increases in performance, durability and fuel
