Shifting Up
Hi guys,has anyone here converted a defender 90 from manual to auto?,if so does the brake master cylinder have to be moved,or is it just a case of the bigger auto pedal in its place,
 
Master cylinder remains untouched,

No need to change the pedal either, well I didn't and it's been OK like that for 2 1/2 years.

Why not leave the clutch pedal in place too, it confuses the hell out of anyone who "borrows" the motor :D
 
this is a mod i will be doing shortly all i need is time, good weather and some rubber hose for the oil cooler,i have got a disco auto pedal that i am going to use instead of the 90 pedal, i will not be using all of the pedal, just grinding the bit the rubber pad fit on to and rewelding it to the 90 pedal.
 
thanx guys,im sitting here( i can`t belive i have done this )i for got i needed an oil cooler, it went to the tip about a month ago,(my conversion was going to be manual)what a plank,lol o well need an oil cooler now ,thanx again,:eek:
 
If you get any photos post them or any problems.
Mine is a 200tdi with the 300tdi box i have had to get an adaptor plate and will need to cut the prop shafts,it would have been much easier if it had been a 300tdi.Just remembered and move the transfer box lever.
 
Mine is a 200tdi 110, but with a 3 speed auto. As far as I know its hard to get a auto to fit a 200tdi. Mine has an adaptor fitted. You will need new/replacement props as well as the box is longer.

ok,i was thinking leaving the transfer box as it is and remove manual gear box,replace it with 4speed zf and v8,(do the mounts have to be moved on a defender that hold the engine or will the v8 go stright in with the origenal gearbox?)
 
Without seeing how long the boxes are you may end up with the engine tofar forward.

Looking at mine, the enging looks like its in the standard place, but the front prop is longet than the rea, so I have not had trouble with them since I lifted it.

sorry don't know but i do know the zf autobox is longer than the box i have in at the min so will need to redrill the chassis and reduce the length of the rear shaft and lengthen the front this is going to cost bout £90 to do by a local prop shaft works.This will mean that the hi low leaver will be further back as well,but have spoke to someone on another forum and know how to sort this without cutting the tunnel,just waiting for a sunny day now and a few days off work to start the job.
 
Here is my cubby/gearlever box its only temp i have other plans for the lever.
The adaptor plate i had to get this from the dealer.

I cannot be 100% sure, but a mate of mine has a Ninety with RR V8 and ZF 4 speed 'box fitted to the Ninety transfer 'box. The transfer 'box sits on the original chassis mounting points [which leaves the Handbrake & propshafts as standard], but due to the longer ZF 'box the engine does sit forward in the engine bay. However, IIRC it still uses the original mounting points on the chassis.
 
So all is not lost,lol your saying the transfer box is in its normal place,can understand that,and the v8 mounts are in same place to? so should all fit?dont matter if engine is forward coz you can get away with an electric fan in sted of viscus fan,minor adjustment to anything else thats in the way,sorry whats IIRC,i know im asking alot here,( if you don`t ask you don`t get,lol) you say your not 100% sure but can you ask your mate if the mounts all line up,know transfer box and props hand brake will be fine its just the v8 mounts and zf box im wondering about,many thanx mark, (don`t worry im printing this lot off and adding to my list of info,lol
 
Hi Rovere8,
I'm in the middle of assembling a 90 with a RRC V8 and ZF auto trans. The engine mounts were moved forward but the g/box ones remained the same. I've just fitted the fuel tank and tried to fit the seatbox but found that the trans is to far over to the right. The 90 was an ex 2.5 NA diesel so I'm going to have to cut out the seatbox and make a trans tunnel as well. Also I've found that I'm going to have to cut down some 110 prop shafts to fit.

As to the pedal issue I've just kept the standard gas and brake pedal, the gap for the clutch pedal will make a good foot rest place.
 
This is confusing me now,lol trans as in transfer box? yeah,
sandym,said you can use origenal transfer box and leave props and hand brake as standard,(mind you sandy did say not 100% not sure ,im waiting for sandy to get back to me on that,we will get there in the end,lol

Sorry, trans is transmission. My transfer box is part of the setup. I think its a LT230. IIRC is If I Remember Correctly.
