Ok here is where I’m at…. I am keeping my 2.8, maybe swapping to a 3.4 soon. No I’m not interested in any other engines. I have a 4l65e that I want to put in. I already know that I need a stand alone controller, shifter will require modification etc. Has anyone done this and what torque converter did you use? The 2005 Corvette torque converter has a small bolt pattern that I can bolt to an S10 flex plate but has 1400-1600 stall speed (a little low). The Colorado 2.2 bell housing is the same as a 60 degree V6 but has a 298mm input shaft so probably won’t work for a 4l65e. Or has anyone put a 4l60 behind a 2.8/3.4 motor? I know that an older S10 700R4 is also an option but they are early 700R4’s and everyone says to avoid them. I’m really wanting an electronically controlled transmission. Has anyone done it? Thanks!
