98 Fbody to 0411 Conversion-TCC issue Hey guys,
Continuing on this lets be generous and call it journey, finally have the car running and driving but have a TCC error. Trans will shift through all gears into OD but the TCC will never lock up ( brand new billet just cut open and checked ), the only Code I am seeing is p0740 TCC...the Car is a 1998 Camaro 6 speed that I paid to have the harness converted to 4l60 and 99-up 0411. Just left the Trans shop last night ( new built trans now ) and he pulled the pan and replaced the TCC solenoid and internal harness...still same thing....no TC lockup at all....kind of stumped...Does anyone have a programming suggestion OR maybe a photo where I can see which wire is supposed to be delivering the TCC command to the trans ( using a 98 harness pinned for 0411)?
Could the clutch pedal have anything to do with it, I did have to push the clutch pedal down ( it says down ) for the starter to work?
Already spend to much money...please help...

This was 2 issues, first the 98 t56 body did not have the normally closed 12volt from the brake switch to pin 33 on the PCM which breaks the TCC circuit ( pin 42 ) when you hit the brake....
Once this was done the 0411 I had must have had a grounding problem internally on pin 42 as it was always on...I ultimately had to put my tune on another ECU and it works fine...well except it wont **** 2 to 3 at WOT...
