The spacer....is not an issue the first time it is installed all matched up.,. Shops that do not have a4ld comebacks are those that replace them for specific reasons...
..though this is a 2.3 application....it relates because the 4.0 was in front of the most a4 based units ....
anything with the 4.0, at least to the initiated...is a pia to match when mixing up years and donor models..and computers and wiring and gem modules...transfer cases....even 2wd slip yokes....and flanges have variance.
it sucks..... Non stop running changes.....
and the a4ld goes hand in hand.
Sure you can get lucky.
Of course If you know what to look for and how to make sure it fits together correctly it's not usually a problem....but if you know that ..you won't be here asking. I can't teach that from here.
I have done many 4.0 swaps....and I specifically recommend a complete matched setup from a single known working donor because of that....
But almost always that was not in the works...as a c4 was involved on a majority of swaps or a manual.....
Putting modern 4r55 e in is possible....but is not ideal. When you piggy back the pcms there are many compromises and the wiring is a trainwreck. I have had limited success...so I don't recommend it.
I have done this in just about every way with rangers ....2wd to 4x4.....and vice versa...stick to auto and auto to stick.
Bottom line is simple.
Matching the flex spacer and converter is ideal when working with this scenario
Sometimes gathering all the information about a problem is like fitting together the pieces of a puzzle. Finding out about differences in Ford 4.0L converter pi
