Getting both of these right means having the right combination of cams and arm length on the throttle linkage.
Some accessory kits, like the
allow full adjustment and correction of TV cable problems.
The COMPUSHIFT Mini is a valuable aid in doing TV cable adjustment because it can display line pressure on screen
in real-time. The cable travel and slack can easily be adjusted to their proper limits because:
When the pressure starts to increase, the slack has been removed.
When the pressure stops increasing, the cable is at its full extension.
1.3 GM 700R4 / 2004R
During the years that GM built these transmissions, a number of different combinations of internal switches and
wiring looms were fitted. The transmission must have a proper internal wiring harness. It must use a 4th gear
pressure switch that is normally open and switches to ground when 4th gear is engaged.
The following are recommended wiring looms:
Rostra 350-0045
NATPRO 51870U
TRANSTAR 54425B
The following are recommended 4th gear switches:
NATPRO 51876
TRANSTAR 74411B
1.4 Chrylser A518 / A618
Your engine must have a throttle position sensor in order to use the controller. Aside from being in good, working
mechanical condition, no specific preparation is required for this transmission.
1.5 Additional Planning
Prior to installation, you'll also need to decide:
Where to mount your COMPUSHIFT Mini Controller.
Where to install the firewall grommets for your wiring harnesses.
How to route the wiring harnesses to the engine and transmission.
1.6 Other Considerations
COMPUSHIFT Mini can provide an electronic signal to operate an electronic speedometer.
