3L30 lock up control

[fixkick]

one more point some 2.0L PCMs (ecu +tcm = pcm) want to see that 4speed box there, and if not goes to nuts,  with lots of DTC errors and gets confused.
but that depends on the year, or as the  the sidekick moved the TCM box in the ECU in 1997, 4speed.
the ECU knows what box you have due to TCM tells the ECU what box is there and changes mode or has 1 pin grounded in the PCM telling it what transmission is there.
each year are different.
there are no easy swaps for sure with automatics.
name donor car first.  then things get vastly more easy, (hope) make , model  year, trans type, PCM model codes, 2wd or 4wd and all that, the full spec, on donor car, is needed.

Well ..the Tracker that I pulled the 2.0 from was a model year 2000,.A 2dr 5spd,.2wd..But,.I’m not sure that any of that matters,.as the ECU had already been pilfered..And I’m wondering if a 2.0 Automatic trans ECU could be used to control the 3L30 T converter lockup. Or run the engine with a manual transmission ECU and use other sources to operate the T.C.. I’m in the process of gathering wiring diagrams.,but thought maybe someone had already done this..It seems that this method would be software intensive..,and the Aisin 4spd installation well..would be  More of a nuts and bolt and fabrication. ordeal..
