The auo matic trans needs the TPS to determine shift points. Swap the TPS off the old engine onto this one and set it to .5volts.
You failed for NOx because your EGR is not functioning. Recheck your vaccum lines and see if they are routed correctly. Also look at the hose under your BPT. If it is burnt out or collapsed. If you dont know what I am talking about do a search within this forum for both current and archived content on TPS,EGR,BPT and/or failed smog. There is alot of info on all those items.
