156 manual gearbox problem

Hi I have a 2003 156 1.8 t spark, and it has started jumping out of 5th gear, I have also noticed today that the gear change has got harder mainly from 4th to 5th. Is it the gearbox or the gear linkage? how much would a second had gearbox be and is it hard to change / time? Thanks

I have a 2002 2.0 Selespeed that also started jumping out of 5th gear. After searching through similar posts on this form I followed this guide How To... Remedy a non selecting 4th Gear to taking the gearbox end cover off; no swarf but the sleeve nut on the gearbox shaft was loose.
On inspection, the splines on the synchro sleeve were chewed up.
Replaced sleeve (70) and sleeve nut, torqued it up properly and swaged the sleeve into the keyways on the shaft and now I have 5 gears again.

So I would suggest investigating behind the gearbox cover plate first; it only takes 10 minutes to find out and if you are lucky it will just be a loose nut.

By the way you will lose a little gearbox oil and you will need some sealant when putting the cover plate back on. I used Blue Hylomar.
