Default swapped engines strange things happening

just finished swapping in a new 3.0 for the ranger. its runs great when worm but right when I start it in the morning it stalls out when shifted into gear, and the tranny is acting weird. 1st is fine but it quick shifts 2nd and 3rd and goes into overdrive. went down to napa and had them read codes and came back with TPS reading low. when we swapped the motors we also swapped the old intake onto the new motor. what are your thoughts

could just be the TPS as the code says. Pls insert a signature, if you truck is an older model and its the orginal TPS then it could affect a lot of things like youre discribing. It would do the same to my 2002 Sonata.

let me also add that during the swap we also changed the filter on the transmission. can you install a filter wrong, giving the transmission low oil pressure causing it to shift strange giving me those symptoms?

Have you made sure that your MAF on your intake hose is reconnected?

^yes. and btw tranny had great pressure. i'm just going to throw a new sensor in and go from there. most likely the tps is causing the problem and not telling the tranny when to shift, this explains the quick shifting into overdrive and the bad starts. hopefully it also cures the shuddering during takeoff

sensor fixed the rough starts and the shuddering. also noticed it was actually downshifting during heavy acceleration. just got to go get the codes cleared and see if anything else comes up
