Sierra Style MT75 Gear change question
spegru - 30/11/14 at 07:58 PM

I've managed to mate a Sierra MT75 gear lever extension frame to a Transit MT75 gearbox - the type that has a very short extension frame at the back not the ones with the lever attached directly to the box (if looking for these on ebay search for Transit gearbox not MT75 as you will find alot more!)
Because I couldn't find the correct Sierra one I've made an actuating lever for the extension frame to connect to the actuating shaft, by welding some bits onto the otherwise unsuitable Transit one.

However there is no centralising spring effect at the gear lever at all. It seems to work ok but, it's loose left to right. I'm wondering if there is something missing from the extension frame which was very second hand?

No, I made my own and the gearbox centred the lever.

Hmm. I wonder if that means mine is broken in some way.
Or maybe the Transit box doesn't have a sprung gear lever? Anyone know about that?
I suppose I could rig something up with a pair of springs if needed - if it's not actually broken

BTW I think this type of box is from a y2000ish Transit Mk 6. Later ones have the gear lever alot further forward, only just behind the bell housing - although I bet with a bit of ingenuity those could also be made to work in a non-Transit installation. There are loads of Transit boxes on ebay

There is a spring on the selector rod in the gearbox that should provide a Neutral detent feel
