    ok i have already gotten allot of help on this from some of you guys, thanks allot to thoes of who helped. Anyway I am putting a sm465 into my 88 4x4 auto blazer and i just wanted to makesure i have everything as i want to try and get it done this week end. Anybody have and last minute suggestions or tips / tricks, also any small parts or stuff that is likely to be overlooked i think i have everything but im not sure. And finally the question i havent been able to get an answer to do i need to do anyhting with the computer ive had about the same # of people tell me yes or no so i just want to know if i do what will happen its just going to idle roughly and possibly stall correct? I called my pontiac dealer (yes not chevy the chevy dealer sent me there) and the guy swears i wont need to he says he has the same truck and did the same thing so i figured ill put in the trans and drive it down there if it feels fine then ill leave it if not ill get it reprogramed.

    You will trip the service engine soon light and pull a code for no lock-up on the convertor but that's about it. If you need to pass smog i'm not sure how fussy they are where you live but here in California if the check engine light is on it automaticly fails a smog check.

    The SM 465 is HEAVY especially if the transfer case is attached. I used an engine hoist throught the window to pick it up so I could wiggle it into place...

    The programming IS different between a manual and auto truck, there is no question on that, the question is, will you notice?

    This is the same as some people not running a vehicle speed sensor and having no problems, others hook one up and voila, the problem(s) are gone. Totally random whether it's a problem or not. It's not right, but whether it's really problematic or not, eh.

    Gist of post=try it and see. :)
