Now that I think about it more, when I had this tranny built, the shop told me to be sure to have power to the thing on the side (don't know what it's called) that allows it to shift into 4th gear. When no power, it doesn't shift into 4th. And he told me it was very important I do have that hooked up, as the transmission would overheat if driving over 55 without that. I thought he said it didn't have a pump. But it was most likely a misunderstanding.

Since posting a bit ago, it has cooled of some, and I went out and looked at the tranny fluid. It is obviously darker. I am pretty sure it has something to do with overheating. The fluid even smells off.

So, bad pump sound like a likely option? Do you know if that can be replaced w/o having to pull the transmission?

[edit]
Regarding the cable adj: Last year I put on a 'kit' from Bowtie Transmissions for this trans. I checked settings/pressures, and conferred with them and got validation of that. I don't think that is it, but who knows.l
sounds like you might not have your torque converter lock-up kit installed properly. if its not you may have a torque converter gone bad. make sure you have the sw. wired right. i think what you need most is a trans. man. thats some of the weak points to the 700-r4's trans. shift cable and conv. lock up.
