Assuming you have a auto tranny, it might be the tcc solenoid. From what I have read here and have been told, just unplug it when the tranny is cool. If disconnecting it helps then you need to replace it. There are a couple good links on this site as to how to change the tcc. Here is the directions on how to change it. I found this on either this site or maybe http://www.v6z24.com. This is another really good site for info. Sorry for not giving credit were credit is due. Will try better in the future to give author or any other info crediting the help.

TCC REMOVAL

It's a fairly easy job! You have the 125c tranny in that cav. Jack the drivers side front corner up till you can remove the wheel (place a jackstand under the car!) With the one corner raised you will not loose any fluid changing the solenoid. Now remove the inner splash shield. It is held on with several 7mm screws. Once thats removed you will see the diff side cover. You will also see the two tranny cooler lines coming in on the left side of the cover. They both will need to be removed. You will lose a little amount of fluid from them but nothing major. Now remove the bolts holding the side cover to the differential. The top ones may be hard to get but you can get them with patience. Now remove the cover. You'll be looking at the valve body now. On the bottom of the valve body you will see two wires running to a small round solenoid bolted with on bolt to the bottom of the valve body. Remove the bolt and cut the wires going to the solenoid (make sure to cut them as close the the solenoid as possible! Now take a small pick or hook tool and remove the plastic sleeve that most likely stuck in the valve body after you took the solenoid out. Now the aftermarket solenoid will look slightly different. The bracket may seem larger. This is because several aftermarket solenoids you must trim the bracket to fit your trans. The directions will show you where to cut depending on which tranny. Now match the colors of each wires and splice them to then ew solenoid using the provided non crimp connectors (most use these). now simply remove the old differential cover gsaket and replace the cover with a new gasket and reassemble it as it came apart. Make sure to hook the tranny lines back up! Now lower the vehicle and check the fluid level. You will most likely not have lost enough to make a difference on the stick.

sounds like the tcc to me. i had to replace it on 2 of my vehicles. tho i didnt have to remove the tranny lines in order to get the bolts out, i just had to bend them a tad in order to squeeze the ratchet in there
