1 Preparing for Your Installation
Take the time now to plan your installation – it will save you more time down the road!
1.1 Engine Preparation
When you ordered COMPUSHIFT II, you had to choose from one (1) of three (3) Throttle Position Sensor (TPS)
systems:
The AccuLink TPS for vehicles with Edelbrock AFB, Holley and Rochester Quadrajet carburetors;
or
A wiring harness for Electronic Fuel Injection (EFI) vehicles that have their own TPS;
or
A Cable Operated TPS for all other engines, including older diesel engines
NOTE:
Please contact your distributor or
right away if you're missing the required part(s) for
your specific TPS system. Before starting, we highly recommend reading all of these instructions. Think through and
plan your approach. It will pay off!
1.2
Transmission Preparation
Find your transmission from the list below and review these specific tips:
Installation Notes for GM 4L80E / 4L60E Series
Installation Notes for Ford AODE / 4R70W / 4R100 / E4OD
1.3 Additional Planning
Prior to installation, you'll also need to decide:
Failure to follow all instructions may cause damage to COMPUSHIFT II, void its warranty, or damage to
your vehicle.
COMPUSHIFT II cannot properly operate a malfunctioning transmission, and a malfunctioning
transmission may damage COMPUSHIFT II and void your warranty.
Your transmission must be properly installed and in good mechanical condition before using COMPUSHIFT
II. A qualified transmission repair shop can inspect, clean, install and/or rebuild your transmission as
required. If there are any questions about the condition or type of transmission, please contact a qualified
transmission repair facility, HGM Headquarters, or one of our distributors for a recommendation.
