NOTE: I could not load pictures from my hard drive, please refer to post link below for photos of sockets.

Today I cleaned the Shifter selector and the A & M switch contacts, they were not bad looking.
I did a reset of the onboard computer - Disconnected the cables from the battery and "Shorted them for 20 minutes".
Please supply the " Magic Reset" instructions - Where the doors are locked and then unlocked, etc... I apparently failed to print them out.
I checked the shifter cable - Looked Ok -
I identified the transmission as a 4 HP - 22 ZF -
I checked fuses 1,15, 17, & 20.
I confirmed that I do have Kickdown switch under the gas peddle.
( It did not appear to compress under pressure, should it ? )
I did confirm that Park does engage, while it does appear to be the only gear.
I have located an OHM meter and ready to dig deeper.
I located two electrical sockets under the hood -
* The diagnostic socket - 10 points - not numbered
* A numbered 25 point connector just behind the Diagnostic socket.
I am looking for test that can be ran on these two sockets with an OHM meter.
( Picture at mentioned link mentioned )
Neither socket look like the 7 point and the 8 point shown below.
Are the 7 & 8 point sockets located somewhere else?
( Picture of sockets at link mentioned )
Where are the connectors mentioned below located?
Any picture of the above connectors?
http://twrite.org/shogunnew/topmenu.html Suggested tests of:
Transmission Control Unit Connector,
Motronic Control Unit Connector,
Program Selector Switch Connector,
Transmission Range Display Connector,
Other tests that need instructions:
*How is the torque converter tested? Says that the convertor is either engaged or not / on or off/ This test is important.
*Output shaft sensor
*Transmission oil pump test
*Transmission pressure regulator test
*Band brake regulator
The next two sound serious - Must
*Magnetic Valve ( Shift ) Solenoids ( MV )
All magnetic valves (except THM R-1 to 12/95) are supplied power from an internal relay
located in the TCM. The magnetic valves are switched on and off by final stage transistors
in the TCM. During failsafe operation, power to all MV’s is switched off by the internal relay.
*Emergency Program
When a malfunction occurs within the transmission, the Emergency program (failsafe mode)
will be initiated. The Emergency Program will prevent unintended gear engagement and
ensure driver safety. The following will occur during Failsafe Operation:
• All shift solenoids are de-energized via TCM internal relay.
• The pressure regulation solenoid is de-energized resulting in maximum line pressure.
• The Torque Converter Clutch is de-activated. ( Interesting )
• The Reverse Lockout function is cancelled.
• Shift lock solenoid is de-energized.
Any test instructions or component locations would be greatly appreciated -
I should be able to come to final conclusion soon -
Thanks to everyone -
