I have a 01 isuzu rodeo, it factory has a delco ecm and runs a gm 4l30e transmission. The stock trans is very weak and begining to slip, with my current lift and 33s its life span wont be long. Ide like to swap in a 4l60e, I have the mounting etc. All figured out, the only problem is controlling it. I dont want to spend the 600$+ on a standalone controller and was hoping to run it off the stock ecm. Is it possiable to remove the 4l30e files and replace with 60e? They are controlled diffrently so im not sure if something like that is possiable. My second thought was can a ecm be programed to run as a stand alone? I could add a second tps, vss etc, and just use it to shift the trans? I dont have much knowledge in tuning or ecm mods so im sorry if anything about my question is stupid. Thanks
