I was going to do this on an A31 Cefiro but didnt. I did a bit of research etc and have an idea on what parts you need:

Box

Clutch

Master Cylinder

Tail shaft

Pedal box (I was told an R32 pedal box would fit in the ceffy so its likely to fit the C33)

Hand brake assembly (my ceffy has the old school foot brake)

Shouldnt have to change ECU etc as to my knowledge these run independent boxes.

I think thats about it from memory. Hope this helps

Yes the pedal box fits both A31 and C33, you also need a manual brake pedal (narrower), and manual footrest (also not as wide as the auto item)

Auto transmission is run on an independent ECU, which is located in the driver's side kick panel, the engine ECU will run fine without it. The only part you need to worry about there is rigging up the neutral-position sensor, or bridging the connector, to trick the car into starting, otherwise it will won't think it's in park/neutral and the starter circuit doesn't work.

So the box has its own ECU? is that then connected to the engine ECU or its just on its own?

[Nic_A31]

It's partially connected to the ECU via the dash loom but for the most part it operates on it's own.

I think the TCU needs TPS signal from the ECU so it knows when to shift.

cheers for that

Maybe just get one of a manual 33 or 32

[Nic_A31]

Guys this has been covered a hundred times.

Search.

[Samgrainger32]

ive had a search found heaps on ceffys but laurels and c33 are a dark area and every one says diffrent things..

[Nic_A31]

Everything between Cefiro and Laurel is interchangeable except rear door cards, glass and fixed body panels.

They're the exact same chassis with a different shell on them.

Is that right? I didnt know that. Good news as I may be wrecking a ceffy soon (if it doesnt sell) and if parts fit on Laurel, well that means bigger potential market for me.

[Samgrainger32]

really thats a sore i can relax on the manual interior parts now and just have to sort tail shaft and crossmember out ive read that crossmember 'B' is the one to use and have checked my mates crossmember on his factory manual c33 and it is a B but will it fix with the 25 box thats the question fingers crossed as we both are about to take on the same things

Does this apply to C33, C34 and C35 Laurels?

[Nic_A31]

C33 only.

C34 and c35 i believe share s14 and s15 suspension parts respectively but thats it.
