Hi, got a mk3 1988 2lt petrol dorma transit with 4 speed type G gearbox. can this be changed to type mt75 from 1993 tansit minibus? and if so do i need any additional bits for it to fit.

cheers

You will need the crossmember and possibly the proshaft. Other than that it sould be an easy swap.

Is the MT75 from a petrol if not I don't think it will bolt straight onto the engine!

i think the transmision tunnel should be big enough, but you might need to relocate the gearstick hole to the centre of the tunnel, and yes fred is right , crosmember and prop for mt75 will be required

Good point MRMP! you will need and adapter plate, if it's off a diesel.

Hi all, many thanks, picking up box on friday with gear selector and x-member. quick question will my prop fit the mt75 drive flange or I am best picking up the first section of the prop with the gear box and join at the universal joint.

cheers

[MrMPuk]

Is the box from a petrol then?

[FredTransit]

I would get the whole prop just to be sure.

hi, sorry about the delay got a realy slow connection. the new mt75 is off 2lt petrol on a 1993. would i need full prop shaft or just the first part.

again many thanks for your help.

cheers

i guess you might be able to get away with just the front section, if the 2 halfs fit together, and if the rear section was up to the job.

but, i would recommend swapping the whole thing as it would have been balanced in one piece from new

you will need the prop..i think the front flange is diffrent..the type g has a spline on the gearbox with 3 bolts..and the mt75 has the flange as part of the box and has 4 bolts.best to get the prop.....but check what prop you have first just in case...and if you can take your old prop with you.and you will need to cut a hole in the floor if you can cut the bit of floor out of a scrap one.
