Right then... I am having thoughts and they might be some of the most silly thoughts on the planet, so bear with me....
Can't remember where, but somewhere on this forum i read that the designation for the 5 speed manual 'box is F25 - which is one of the designations that Vauxhall use - another GM stable, would I be correct in saying that this designation is due to both boxes being the same unit?
First silly question over.
Next one, if this is the same unit, and hypothetically speaking I were to be in the market due to need or want to change my tranny (obviously with our trannies being so bulletproof we never need to make these considerations:roll: ) would I be able to drop the (significantly cheaper to get hold of) Vauxhall F25 in, or if i were feeling adventurous, the 6 speed F28 box should the ratios be suitable - subject to calculating etc.
Just a thought, not a plan. Although I have come to like this GM thing, I have found a few bits and bobs out there that are cheaper because they dont have Saab stamped on them....
I figure this is a performance question because if the latter idea works out well, it would surprise me if a bunch of 6 speed 900s didn't turn up if the ratios worked out for either/or better acceleration/top speed.
Something to think about there. (and it will get those pesky vauxhall tuners back, they apparently steal all our parts from what i hear!!)
