yeah I checked fuse, and the ecu is scanning properly and monitoring rpom and tps like it should so Im assuming this is good.

Trans is unknown, but throwing out every single solenoid and tcc electrical code at once seems odd, and et kinda want to work like it should for a sec when I erase them. all the wiringharness is complete from a 2002 blazer. thats why ide rather make sure the programation is good or not before opening up the trans and all that.

this is what I followed, in my case, trans is already wired up to the ecu so I only spliced all the required 12v ground and sensor into the 0411 from the astro and seems to be working as it should. I could not follow the instruction on tuning since I only have tunerpro
