e4od is doing the lurching between like 25 and 40mph.

The Fipl was a little off, but not much, idle voltage after warm was 1.15. I got it so it's now 1.07 and WOT is 3.9 which from what I hear is what I want.

The TC only starts the lurching once the trans is warmed up, so i'm wondering if it's the TOT sensor (trans temp). I think this sender is involved in the TC Lockup circuit. I also am having a hard time figuring out where the TOT sensor is, can anyone throw me a bone on that?

I also did the manual lock up mod which works well, but i'd really like to fix the automatic. I've already forgotten to unlock it twice!!! (did not sound good)
