Transmission Surge

[scottv]

My 1999 Sport with 80k has developed a surge while driving and maintaining say 2000rpm. It's as if the tranny is slipping or something. Is it advisable to have the trans flushed or is this something I might be able to do myself? I have about every tool Craftsman sells and pretty good mechanical skills (hey I put a clutch in my Sabb 900 SE Turbo).

Thanks in advance!
