Has anyone successfully swapped a different gearbox from another Toyota into a Glanza? I'm thinking MR2/Celica/Corolla/Yaris rather than the wideley known G6/G6R.  I know there's been all sorts of discussion over the years of swapping various gear sets into C56 bell housing but what can actually be done? I had my Glanza gearbox rebuilt last year and it's still useless, takes forever to get into 2nd, crunches a lot, feels like someones pouring a bucket full of nuts and bolts between the cogs w
