I currently have a mk3 1.6 8valve Astra (P plate) and have a problem with it jumping out of 5th gear.
I recon I would probably be as well getting a recon box but I have 2 questions first:
1. Has anybody else had the same problem and was it easy to fix
2. How do I tell what model of gearbox is in it at the moment.
As always just trying to get it sorted as cheap as poss.
