I just rebuilt my 4.3 vortex in a 1994. I now have a list of enigne codes. If anyone out there can help me figure out what these codes are I would be very grateful.
23, 59, 66, 67, 73, 82
Thanks in advance

Have you look at this board yet?

There are pages and pages of codes explained. I'm sure yours are in there somewhere.

If you do not yet have some sort of service manual for your truck I suggest getting one. They can help in all sorts of ways.

OBD1 trouble codes are available from TroubleCodes.net:
23 - Inlet air temperature sensor signal showed an air temperature of -29*F for 4 seconds.
59 - Transmission Temperature Sensor Circuit (Low Temp)
66 - 3-2 Control Solenoid Circuit Fault
67 - Torque Converter Clutch (TCC) Solenoid Circuit Fault
73 - Pressure Control Solenoid Error
82 - 1-2 Shift Solenoid Circuit Fault
That is an awful lot of codes for the transmission. I would be looking into the grounds and electrical connectors to the transmission.
Concerning where the transmission temperature sensor and CKP sensors are located, the transmission temperature sensor is located inside the transmission pan and is integrated in with the transmission pressure sensor (large plastic thing bolted to the valve body) and the CKP sensor is located on the front cover of the engine near the harmonic balancer.
And I agree, a service manual is a great resource to have. The best are the factory service manuals. They pop up on eBay for not too bad of a price every once in a while. The FSM will be more expensive than the Haynes or Chiltons manuals, but the FSM is hands down better!
