Fresh 4L60E rebuild, only have third gear. Help!!!! I recently converted my 1990 Firebird(LQ4 engine, Custom speartech harness) from a TH400 to a 4L60E. My Custom harness is a Speartech harness with the wiring for a 4L60E. Im running a Transmission Specialties 4000 stall lockup torque converter.
The tranny has been completly gone through and has all new electronics, valve body, oil pump, etc.
I only have park, neutral, and third gear. No 1st, 2nd, 4th, or TCC. What could be causing this?? My fluid level is right at the top dot on the dipstick and the transmission temp gauge has read as high as 230 degrees on a 75 degree day. I have a 28,000gvwr B&M Supercooler.
I'm in need of some advice on what to check for

The PCM is from a M6 LS1 Fbody and I copied 4L60E files over to the existing tune file.
Do I need to reflash my PCM to a 4L60E LS1 fbody and then transfer my existing engine tune over to it??
