Modded transmissions? What is there and what would you like?

G'day,

I've been searching for a bit of info but have been coming up blank. mostly because I don't know what I am looking for.

I have an old and rusty memory that a five or six speed transmission can be built if it is changed to a crash box so there is enough space for the extra gear(s)

What other sorts of mods are there out there?

No i don't have a fat wad of cash to throw at a custom transmission. Just satisfying some curiosity.

For example, is it possible to have a dual range / overdrive installed?

The reason I am asking is just the result of an idle train of thought.

My ultimate transmission for my van would have a crawler gear and an overdrive, and an LSD of course. Couldn't care less about having synchro.
I love the pulling power of the 1600 box mated to the 1800 type4 on my van, but I run out of cogs by 60km/h and by 100km/h the motor is getting close-ish to its rev limits.

What sorts of things would you like in a transmission? Practical, feasible or completely off the wall and near impossible!

I want to hear what others would like to have.

If I could have a Falcon/Territory ZF six cogger in a VW I'd be a happy feller... and I usually hate autos

Must be better than the ones in the ZL. Terrible transmission.

one of these would do me........i'd need a bigger motor to even turn them over tho

What on earth is that giant from? I like!

mendoela? not sure of the spelling on that
