Gearbox Identification 4spd to 5spd

[kent14sr]

On the top of the selector housing the diagram shows 5 gears but I read somewhere that this was the same whether 4spd or 5spd?

Anyone know if this is right?

And how do you tell if its a 4spd or 5spd box?

[novaguy08]

use the selector move it in and out of all the gears, which gearbox is it on? i got both a 4 & a 5 speed F10 and neither of them have the diagram on it

If it has the diagram its a 4speed box, even though it has 5 speeds on the diagram, and this dones NOT work on a 5speed.

[kent14sr]

cool thought it would be a 4spd but got confused with it having the 5spd diagram bit!

[novaguy08]

yeah that is an odd one?!? it showing you what your missing out on?

[AlexW]

Yep, they all seem to be like that and when trying one of those on a 5speed box it didnt work. Not much gain from changing to a 5speed though, i guess it will mean you wont try for 5th like used to do a lot lol

Think it must be!! When linkage was slack it felt like it had 5 but its a 4spd linkage/selector rod so difficult to tell for sure as once its set right it will only take 4 as I think there is a metal lug you have to grind off the 4spd selector bit near gearstick to get 5 but not doing this if its a 4 spd!

yeah tried that 1st time i hit m-way in mine, was funny as it hit 3rd and i hit the windscreen

I did that once going for 5th with a 5 speed, 7000rpm in 4th at the time, luckily I realised before I'd let the clutch back up fully!

[novaguy08]

bet that would have sent a piston into orbit! lol

[mikey14sr]

Would have if I hadn't noticed the tacho heading way past 8 thou...

all f10s will show the 5 speed setup on the selector housing/turret

to tell if it is a 4 or 5 speed you will want to look through the wheel arch on the passenger side and look at the side of the gearbox. if it has a huge nut (like 30mm or so) it is 4 speed if its very small then its 5 speed.

think it was this way around :D

[kent14sr]

Cheers for that!

Checked it against the 1.3SR and they both look the same from under wheelarch - both have female allen key bolt thingys that look same size!

So can I use the existing 4 spd gearlever/rod? Seem to remember there is a lug that you cut off it to get 5th?

Yep if its a gearstick froma 4 speed Nova then you will need to lift the gear gaitor and you will see a wee nobbly bit on the right hand side of the gearstick lower down, cut this off :thumb:

[novaguy08]

ooo some good info for me :D
sorry got a 5 speed going into my 4 speed shortly and now i know lmao

[kent14sr]

Yeah - maybe worth putting this in how to/articles section for reference!
