Hi VX Kat,
I had the same issue when I bought mine with 135k. I had pink fluid leaking from the trans.area so I was going to change all the fluids anyways including a full trans. service so I figured after I replaced both trans. gaskets, all would be good. Well it wasnt. I thought is was a faulty trans.pan aftermarket gasket so I changed to factory, no change. Finally pinpointed to to the shift shaft seal on the left side (driver's side) middle of trans on side. Took about 1 hour to replace it and the seal was cheap. Mine was failed due to brittle and aged. See my thread I started about this:

Good luck!
