Sorry mate Ive been out for a couple of days, Why is your gearbox fallin out? Your mounts mustve been worn? Sounds like you may need to sling a rear support across the top of the box like a Roadranger. Ive seen a similar result on a V8 with a quad box. The bolts came loose and it fretted and chipped the back of the flywheel housing where it mates against the block. As for jumping out of gear our F model was doing it, it has a 15spd roadranger, we put a heavier detent spring on top gear selector and replaced the mounts and it solved our problem. Obviously the lenngth of the gear linkage had a bit to do with it. Be interesting to hear from you mate. Cheers

I got my truck out of the shop yesterday. Trans was pulled and the broken bolts were replaced, the bellhousing checked out OK. The mounts for the bellhousing were replaced as well as the carrier bearing and the cross member realigned. The guy who worked on my truck said this was a common problem. The truck shifted fine on the way home.

I noticed last night that the trans had a 3/8" gap at the bell housing at the top. Some bolts were broken off and some were missing and the remainder was loose. I tightened some and replaced the missing bolts. The trans worked great today for about 4 hours untill more bolts snapped and the trans moved backwards again. The truck is in a local shop now waiting to have the trans pulled. The bellhousing will need repaired or replaced. Anderson

My R model has a Mack 6 speed and it jumps out of high gear when going down hill. Could it be the gear or the fork?
