Does a shift kit improve performance?
By better utilizing the energy normally turned into heat by slipping during extended overlap, shift kits allow you to instead use that inertial energy for forward motion with quicker shifts, therefore you’re also able to notice improved city fuel economy.
What is the point of a shift kit?
A shift kit is a set of components for automobiles designed to improve how well the car shifts between gears. Kits are made for both automatic and manual transmissions.
How can I accelerate faster in an automatic car?

How many times does a TH400 shift?
I tested it at least 6-8 times and this is what I found. The trans. will shift from 1st-2nd under WOT between 4200 rpm and 4500 rpm’s. It seems to favor the lower end some. The 2nd-3rd shift under WOT happens between 4100 to 4300 rpm’s.
Do shift kits really work?
What should you not do while driving an automatic car?

Smooth acceleration is achieved by maintaining just enough pressure on the gas pedal to keep the speedometer moving steadily upward, until the desired speed is reached.
What does TH400 vacuum modulator do?
The vacuum modulator is a vital component of automatic transmissions. It tells the transmission what kind of load is being put on it, allowing the transmission to react with the proper line pressures and shift points.
Why does my car jerk when I shift gears automatic?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
