It's not a PAIN to replace, but it's more involved than changing an air filter. You're going to need two people for this job also. If you're doing the TOB, you might as well change the clutch also. Basically what you do is take off the h-pipe, take down the driveshaft, unbolt the tranny and take that down (shifter needs to come off), replace the TOB and installation is the reverse of removal.
