Long time lurker but first time poster.
My '83 Leone Wagon recently decided it no longer liked its gearbox while going uphill on a highway. I think it has something to do with the selector slipping out of position (will go into 3rd and neutral but nothing else).
Therefore I'm in the market for a new gearbox, but I need a bit of help. I've never done anything like this and just wondering if I need to get a gearbox from my exact model car or would one from any EA81 fit in?
Or is it worth trying to fix my current gearbox?
I will be taking it to a mechanic as I think this is beyond my capabilities, but need to source a gearbox myself.
It's a 1983 Leone 1800 Wagon 4sp Manual EA81

Cheers.
