The gear change is not hard. You can do it in the sled but I took my case out to do the job. It is easier to split the case on the bench but it can be done in the sled. It is good to pull it out to check the seal and the shaft. Mine had water in the seal and rust on the shaft. I think think there is five bolts holding the case to the tunnel and the mainshaft bolt on the disk side that has to be popped out. Also dont forget to unplug the speedo pickup from the case.
