Id say the seals are dryed out and the bands are to , it wouldnt hurt to put some transmission care products in to see if it helps, they have some stuff, at the parts store that is supposed to help dry seals and such, and theres probley gunk built up in the valve body also , and wont let the fuild push under pressure like it should , you might take it to a quicke stop oil change place, and let them do a complete transmission fuild change, they have a machine that will do that, and push all of the old fuild out and push in new thta might also break up the gunk , it costs about 89.00 or used to , hope this helps some way
