1998 Nissan Maxima Irratic shifting

Transmission problem
1998 Nissan Maxima 6 cyl Front Wheel Drive Automatic 175k miles

Transmission will shift fine in manual 1, 2, drive. While in drive it will shift from first to second pretty quick, but after shifting wont engage, just rev. Is there any vacuum lines or modulators anything of that sort that may be causing the problem? Please help, don't want to replace trans. Thank you.
