So ive had my freshly rebuilt 2004r in ny car for about 20, 000 miles now. The first 10 it shifted great, 1 2 nice and firn ans 2 3 firm as well under wot and partial. I have noticed for awhile that under WOT my 1 2 shift is basically gone, shifting into second right where it would as if I were just cruising it. I had a very well known trans builder drop the charge pressure in the trans because it was wiping out my thrust bearing recently, and when I got it back all was well for about a week. Now, 1 2 shift is basically the same but ive noticed my 2 3 shift is very soft and short, whether im going WOT or just cruising it seems to shift in the same place, probably around 26mph cruising and 35 at wot
. Does not seem to slip, tv vable is tight and trans fluid is full. Seems to shift fine if manually shifting. Governor/throttlebody issue?
