manual to auto

[fasthands]

Hi folks, I may have to change my 90 to auto trans, has anyone done it and how difficult is it to do? I have put a disco 200Tdi in mine. :(

I'm thinking of doing the same  :dance:

I don't really want to, but due to my injuries I think gear changing round town will be too painful.

arm or leg injury? Am wondering if there is a servo assisted clutch modification available (like other cars) which allows you to use the gearstick normally but you press a button on the stick to electrically depress the clutch.

Might be easier to swap to a Disco or RRC auto.  You need an auto box from a TDi, I don't know then if a Disco box will fit the Defender anyway.

You'll also need a host of other stuff, small part of the wiring, oil cooler, shifter, flywheel etc etc.

I know some Audis use a feed from the PAS pump for the clutch, light as a feather and surpringly, still very nice to drive. I wouldnt have thought it'd take a lot of work to mod this.

Disco Auto will go straight onto lt77 mounts & you can keep propshafts.  The engine mounts will have to be moved forward by approx 5", this means you will be able to use disco downpipe too.
Transmission tunnel will need adapting.

It was something I seen years and years ago, but it was electrical, I thought a real fast powerful servo operated the clutch pedal via  cable attach to it. My ol'man was looking into it at one point for my mothers car. I think this website details what I recall or something very similar.  http://www.brig-aydcontrols.co.uk/clutch_systems/syncro_clutch.php  Think that one is a mechanical cable clutch, but I guess a electro hydraulic servo thingie could be used.  edit: they detail this version too http://www.brig-aydcontrols.co.uk/clutch_systems/duck_clutch.php

Try contacting Paul Humphries.

He has (or had until very recently as it was up for sale) a 200Tdi 110 auto. He could probably give you a few hints.

[Tommo]

wonder what would happen if you stuck a brake servo in there.

As an alternative to the auto conversion, if you can cope with a light clutch then you could fit a remote hydraulic servo in the clutch circuit. I did this to my 90 a year ago because of a chronic knee problem. The clutch pedal is so much lighter.

Here's a link to the thread I posted at the time, including some pics of the installation.

Hope that is of use.

Sorry for the delay in thanking you for your suggestions, I am having a lot of hospital appointments at the mo takes all my time and energy. I have had both legs crushed just above the knee, by a 68 Mustang at work brakes failed as my boss was driving it on to the ramp, pushed me through a wall, 9 months ago. still having major surgery.
Thats why I was thinking if a auto, but I am going to go down the assisted clutch road I think. the question now is how it can and will be done! Thank you for your suggestions so far. ;)

Martin what was the ratio you used?

[Martin]

I used a 1.9 to 1 boost ratio servo. I was tempted to go for a higher boost but worried about the impact it might have on the seals in the slave cylinder.  As it is I think the 1.9 to 1 is more than sufficient - certainly for my dodgy knee anyway!
