At least on 98+, you need 8mm, 10mm, 19mm / 3/4, 12mm 12pt; all in both sockets and open/closed wrenches. basically you need a nice small tool collection. Literally...all the parts you need are found in one of those $150 craftsman toolsets. I know on 2001+, the flywheel/flexplate are held in with #12 inverted torx bolts...so you'd need that socket to remove the flywheel. The hole job can be done using basic handtools.
I've got the job done in a little over 7hrs from pull in to drive away.
