I've had it with this 904, about to give up!

Yes I checked the TP on both valve bodies, I don't think that's it. TF2 kit says to make the little deal flush. So PoisonDart, were you talking about the air check or the mainline check? I have the BPE kickdown cable kit, I'll try setting the lever fully engaged and see what happens.

my5thmopar - no the TF2 kit didn't come with a new accum spring and I had to go back thru the directions to make sure but it didn't come with a yellow spring. I was just making sure I put the right one in there, because when I saw the yellow spring last time I worked on it I was like huh...seems weird that spring is colored like the TF2 springs but came out of the original trans.
