    Cutting out the cat usually will only throw rear sensor code if it throws one at all. Often times it throws nothing but it will run richer. The front 02 is the one that controls air/fuel ratio and will be seeing more air and to make up for it will push slightly more fuel. Not a huge problem but one to expect. The rear simply monitors cat efficiency so it might throw a code indicating a failing cat but nothing to worry about. Whichever throws a code if any can usually be cleared by using spark plug non-foulers to space it out of the pipe a little bit.

    It looks like you're going for the 360 build, nice choice ;)

    You may consider beefing up your transmission. You can get some nice upgrade kits that will greatly reduce the common problems with the 46RE transmissions for about $400.

    Most commonly, the bands burn up and the solenoids go bad. Just getting a $200 band and solenoid kit goes a long way, especially if you plan on driving it hard or are going to tow with it a lot.

    For towing, a tranny cooler is a must, you will fry it otherwise.

    Shift kit, check valve delete, Hayden 405 cooler and you should be more than good for what you're doing.

    I've been looking into trannys to just replace the 46re. I'm the 3rd owner of my 01 and the trans blew at 170,000 but it was not taken care of by previous owners. I can either upgrade my trans cooler or install a second stock cooler (from my parts truck). See this is where I get stuck because I'm very indecisive at times lol I have a whole other truck I could parts from and rebuild the trans to make it what I want, or buy an aftermarket HD trans. I've just never seen these 46re trans take a beating very well, then again I've only ever seen them stock.

    Heres a quick question, something I ran into yesterday. How hard should it be to separate the transfer case from the transmission? I feel like I shouldn't have to pound and pry in all directions with hardly any results lol its still in the truck and its time for it to come out.

    You got all the bolts out? Even ontop? Nvm. I just remembered. It slides over the trans shaft. I had to split it like u would a wheel bearing hub assembly lol
