Transmission connector test point pin locations and what they are for.

I designed this slide to let you know that PIN E is voltage for the 1-2 shifting solenoid. The 2-3 shifting solenoid and the voltage for the Torque converter clutch solenoid (TCC) solenoid.
The computer chooses to ground them and when it does shifting happens.
The voltage is continous and comes from the ignition source.


This slide below represents the Pressure control solenoid. (PCS) (Force motor) This is variable width meaning that the less amperage the solenoid experiences the more line pressure the transmission gets. The more pressure the harder shifting.


This slide represents the Transmission fluid temperature sensor. (TFT) This sensor can be checked with a digital multimeter set on OHMS. There is a chart included. The hotter the transmission gets the lower the resistance gets. These sensers are said to be skewed if they do not agree with the chart while testing with OHMS.

Any chance you could repost the images? Huge thanks for posting them to begin with, this is exactly what I need... too bad they're all fuzzed out by Photobucket!
