Alright guys I am ready to do my Nv4500 Swap. I have a complete 96 NV4500 with the matching transfer case and yokes to adapt to my drive lines. I have a clutch pedal assembly ready to be bolted in as well. The rest of the parts will be sourced new from rock auto.
I know that if I remove the gear selector from side of my automatic transmission and leave it plugged in (in the park position) then I will be able to operate the vehicle. My problem is that the ECM will throw codes for the automatic trans. I can't pass smog inspection if the check engine light is on or has been disabled.
I have talked to a couple people who have done the swap on 96+ gm vehicles but I haven't found anyone who lives in a smog inspection area.
My Tahoe came stock with the manual shift transfer case so I am not worried about that.
My question is: can the codes thrown for the automatic trans be tuned out?
I believe that it is going to throw a transmission slip code, but what other codes will it throw?
Sunlitcomet, can you shed any light on my situation?
Thank you,
Kyle
