I have a 76 Chevy Blazer with a TPI system from a 90-92 f-body in it. I recently upgraded my TH350 to a 700R4. I am having trouble getting the TCC to lockup. I built the harness for the 700R4, and wired everything the snap plug into the 700R4. My 700R4 has the type 18 wiring and solenoid wiring that should be right for the 1227730 ECM. I am looking for a .UNI Datamaster file from someone with a stock 90-92 f-body TPI that shows the tranny operation from 0-MPH to highway speed (including TCC lockup) and back to 0 MPH. This would serve as a base line to help me trouble shoot my 700R4 configuration and understand the various bit settings in Datamaster that are changing during the test run.
