I got everything swapped over, but now it wont start, it will backfire and sputter then die, how do I fix this?
Im using a flexplate for a 97-02On 97 thru 02, the MTs use a 2 bolt sensor and the 32RH autos use a 1 bolt sensor. Cost for the auto sensor is roughly half of what the MT sensors cost. But in 03, the auto was a 42RLE and I just did a cross reference at Advance Auto Parts and it uses yet another sensor so now I have several questions because I am unsure. 1) What year model flex plate did you use and are they all the same or did that change in 03? 2) Will you need a different ECM for the 32RH to shift properly?
I'm sure there is someone on here that has made this swap so hopefully they can help you out. I have read a post from Jerry Bransford that he made a 32RH swap in his early TJ (97 if I remember right) and I believe I remember him mentioning swapping the ECM from the donor vehicle that he got the tranny out of.
I think it was off a 2000look online at parts lists and see if flex plates and crank angle sensors are same or different your year and donor year
I know your year TJ used a different auto but what about actual flex plate and CAS
I so think it should work with your PCM as that auto needs no PCM interface except lock up and you can do that seperately independent of PCM but the old manual PCM has to get a functional spark timing pulse from CAS
What was donor year of your auto and flex plate?
