6 Speed D3 box to LT230 ??

[goingbush]

What is / Who makes the D3 Manual Gearbox , not a MT82 by the looks

Check out this guys project to fit a 6 speed box into his Defender with a GMC 6.5 Tdi in front , (don't like his cut & shut output shaft , tick tick )

I'd have been happy with a 2.7 tdci V6 in front.

proves you can fit anything to anything.

Land Rover Owner • View topic - my project, disco 3 6 spd box to LT230 conversion (http://forum.lro.com/viewtopic.php?f=18&t=60930)

now that I think the Ford Territory uses the jag 2.7 Tdci and MT-82, hmmm

The 6sp manual to LT230 has already been done by a UK mob. But they put a decent engine in front, the 2.7 TDV6 (jag version), not a poxy 6.5.

I was looking for info on the D3 6sp box the other day. Found nothing.

But ratios from the D3 brochure:
1 5.08
2 2.8
3 1.78
4 1.26
5 1.0
6 0.835
R 4.73

Final drive 3.07
Transfer 1/2.93

Compared to Defender MT82 ratios they are pretty close:

Transmission GFT MT-82 six speed manual
Full time four wheel drive
Transmission
(high/low) : 1 Overall Gearing
(High/Low Range)
1st 5.443 23.334/62.988
2nd 2.839 12.171/32.854
3rd 1.721 7.378/19.916
4th 1.223 5.243/14.153
5th 1.000 4.287/11.572
6th 0.742 3.181/8.587
Reverse 4.935 21.156/57.109
Final drive ratio : 1 3.540
High range transfer box ratio 1.211
Low range transfer box ratio 3.269

are you saying the D3 6 speed manual has been mated to a lt230?

[justinc]

ZF IIRC Don.

don't use the pathetic clutch they have, too small for a d3. check out the complaints http://www.car4play.com/forum/post/index.htm't=1200

and yes i have done one, and yes they are totally mismatched for that vehicle application IMO.

Forget that ceramic friction disk too.... 30000kms and the disk will still be like new, and the flywheel will have a matching grove all the way around it! Used to fit them to the bricky forklift tractor conversions at request of owners, and we'd be replacing the flywheel, friction disk and clutch cover a year later back to standard!

Dont think we get any manual D3's in OZ, wonder what box they use ? Edit: Just saw JC's comment.

There is a Manual on carsales

Suggests it's a ZF S6-53.
ZF say they are good for 600Nm max.
ZF Friedrichshafen AG | Cars | 6-Speed Manual Transmission (http://www.zf.com/corporate/en/products/product_range/cars/cars_manual_6_speed_transmission.shtml)

Spec sheet here which says 470Nm max for the disco version: http://disco3club.co.uk/gallery/albums/userpics/10057/308_03_02.pdf

I'm wondering if they give a lower torque rating for the same gearset used in a heavier 4wd vehicle?

As the ad states, they are rare. Sneigy said in a recent thread that they had serviced only 2 manual D3s at the dealership he works for.

Yeah i have never seen a manual D3 or a TDV6/L6 Territory for that matter . A manual would make a defender TDV6 transplant a bit easier although i would prefer an auto.

Are you saying the gearbox is mismatched or just the clutch?

The few Auto TDV6 conversions I've seen over here use the ZF4HP22 or 24, specifically where they've been dropped in to replace a V8, although the JE 'Saluki' conversions also use the 4HP24.
I think it's Milner Off Road who do the adapter, somewhere around £300 according to Simtek who do the Bodylogic ECU to run the engine.

Apparently 40mpg is possible with one in a P38.

That would be mu ultimate landy, defender with TDV6 and auto in a Puma .
Although it is tempting for my D1 without so much electronics to deal with.
