I have a '91 5.0 with 175k on the odo. It's got the bone stock AOD. Well it has been having this problem for a long time, and it hasn't gotten worse. I've already checked the tranny fluid and it's all good. Basically in OD, mainly on the highway driving, whenever you gun it (basically enough for it to downshift) it sleps to about 3-4k rpm, then catches and takes off. Also, when going into the last gear, it won't shift if you're foots in it. The only way to get it to shift in to the final gear is to let off the throttle, then when it shifts you gotta barely touch the pedal or it downshifts. I've held it pinned at 115, it had one more gear left, but it never shifted. What is the deal? Thank you all for the help.
