Re: 147 jumping out of 3rd gear
It's dead, the synchro sleeve on 3rd gear is screwed you need a new one.
Exact same thing on my old 1.6 ended up with a new gearbox, started off not centring properly, then started crunching going into 3rd then started popping out of 3rd when under load then finally wouldn;t stay in 3rd at all.
If your's went through these stages then it's time for a new syncchro if your lucky, on mine particles of metal had actually got into the gearbox oil creating a lapping paste and gradually wore the bore of the selectyor shaft meaning the only economical thing to do was get a recon gearbox in there.
Hope yours is fixed more easily.
