Powersteering is most likely a line problem (easy fix)if the pump is leaking replacing it is not to bad either,if it is leaking at the steering box make sure the lines are tight if it still leaks replace the lines first. As far as trans the only really bad seal is the front main you must slide the trans back away from the motor to change it. The other 2,pan gasket and tail shaft seal are easy to fix and all three seals are inexpensive the worst beaing the pan because it comes with the filter but again check for loose bolts first. your oil pan gasket may turn out to be a pain see if you can drop it down enough to slip the old gasket out and the new one in if not it has to be removed,this is when it becomes a pain. I hope this helps bigtn_1971
