Was a bloody disaster,designed for “drivers” who couldnt quite manage a 9 speed crash box,really the fore runner of the garbage “autos” we have today.
All internal clutch and inertia springs, Only lasted for 5 years then Eaton realised it was a pile of crap.

It wasn’t a crash box they were a constant mesh gearbox
There were no or little crash boxes made after the 50s also in the right hands the 9/13 spd constant mesh and 12spd twinsplitter gearboxes were great to use
You only needed the clutch to start and stop
Plus the Eaton twinsplitter was in production for over 15 years and it was down to euro noise emissions that sealed the fate of the twinsplitter not reliability we ran dozens of lorries fitted with the above gearboxes many staying on our fleet for 10 years plus and giving sterling service

Why coment ,the ts was in the E series and still being fitted in 2000 to the EC ,why a disaster ? the back end on one is the only area where repairs are ever needed really and it’s not rocket science to do either .

I suspect I drive a twin splitter more often than anyone on here and even iam sick of hearing about them .And how’d you work that out
Err could be because I have a lorry with one and also because my brother has some too of which I go and load most weeks .
Yea and there’s plenty of ex pats on here that drive them all day every day. The Eaton Fuller box is still pretty much the standard box in Canada and the US
I suspect your not talking about the Eaton twin splitter here ,now iam quite happy to eat humble pie but are you mixed up with the eaton super 10 or spicer 12 because I’ve not as yet come across a twin splitter in the U.s or Canada .
Especially for ROB… 
and for the others, i have an eaton twin split on my mobility scooter, coupled to rockwell rear axle with a coach diff…no caching me now.

Is it a direct top version ? It’s susprizing how many with a high diff are ,I once took a fuller out of turbo star only to find it wasn’t overdrive so no good for a 3:1 erf !

More worrying is I do actually own a Rover 75 am I doomed. (Lovely old car)Should be fine as long as you dont get the urge to place a hat on the rear parcel shelf.
I had loads of Rover 800’s, dirt cheap and a lovely ride, talking of which I lost me virginity in a silver one (true story, not the usual bollox I come out with).
what you came out in a silver rover

So the twin split had syncro hubs.Just like the ZF astronics?
No the twinsplitter was a fully constant mesh gearbox
From memory I think they had a sensor/biocker fitted which was similar to synchronising but this was used when the pre select button was used and not by a full gearstick shift
GAZSA…thanks for your professionalism…but it now looks like your going downhill, so you wont need one of them fancy gearboxes now cos you can coast which is much better than playing a tune on the Eaton Twin Split ( which i`m sure we all did ) but as Robert pointed out there was a difference between a slit and a twin split being 1 gear stick + 2 levers to play with, which basically meant to change gear 3 times without moving the stick to the next gear, till you got used to it then you could skip a few.
Thanks Truckyboy but my latest set of wheels which I’ve steered for the last 12 years hasn’t got a fancy gearstick thingymebobby just a button with
D N R on it but alas I’m being made redundant next April so I’m going to have to learn how these new fangled autos work that’s if I’m daft enough to go back driving
But give me a twin splitter any day
Cheers Gary

It had a logic switch.A constant mesh gearbox has to have syncros.
For the gears to be in constant mesh they cant move along the mainshaft(or they wouldnt be in constant mesh would they)the syncro hubs are moved by the selector forks not the gears.

Now your talking a real “auto” box
Torque converter,and double epicyclic drive.
Everything is always in gear all you got to do is feed pressure to a multiplate clutch or 2.
Detroit box the best box in the world.Because of this gearbox and converter you can get a 250 horse engine to out pull any 500hp “donkey”.
When it comes to automatics the yanks build the best.
Shame about the redundancy Gary…are the firm folding up, or just getting rid of the shunting…maybe get a job driving for them…just a thought…anyway
During the war ha ha

No mate they’re moving production to Poland after a 127 years but the warehousing and distribution is being kept in the UK and it’s being out sourced the firm with yellow lorries with a red stripe down the side have won the contract
They already do our transport (which they can’t run properly not a day goes by without a complete balls up)
It was a TUPE situation but none of the warehouse/dispatch staff or myself wanted to transfer over so we’ve managed to get redundancy
Also our firm as gave us a retraining fund I’ve not long completed my DCPC
I did it over 5 Saturday’s (mind numbing) also I’m doing my Hiab/grab licence plus I’m thinking of doing the ADR so I’ve got some options open
