Every day's a school day Clayton, hope this throws some light on it.
The old box was out of a very old 3.5 RRC, so was quite tired and not really locking up properly, with the 4.6 being a spunk load more powerful, I was finding that on steep ascents up the Peaks it was flaring (like a manual clutch slipping). No Bueno.
It wasn't really the right box to bolt behind a funky fresh 4.6, but the costs had spiralled high and I needed to just get it on the road and use it.

I turned to Ashcrofts as they can build them with bigger/stronger internals..
The photos show parts from a standard box 22 and the strengthened parts 24.

One way clutch



Planetary gears



Plates





Torque converter, the left one is for a 300tdi td5 for eg, middle RR 3.9 and tuned td5, right for 4.6+




A larger converter is desirable on a tuned engine for a few reasons :

1) Lower stall speed, there's little point in having a nice torquey engine if the converter is not transferring the drive and you are revving straight past it. A larger converter will reduce these revs and allow you to take up drive earlier which results in much more relaxed driving. This is by far the biggest advantage of upgrading the converter. Note these reduced revs are not to be confused with lower gear shift points, these stay the same as they are determined by the autobox ECU programming.

2) Less heat generation because of the lower stall speed and reduced 'slip'.

3) The converter has a lock up clutch inside and the smaller one struggles to cope with a stock engine, never mind a tuned one. This clutch can slip as you accelerate when it should be staying locked. In a TD5 the stock converter is the small one. If you have a stock engine, stick with the stock converter. If the engine has a mild tune then we would recommend upgrading to the medium diameter one.

Either colour would look great but I would go for body colour wheels. Is it Keswick green? I remember seeing a Cool'nVintage rag top 90 that looked absolutely stunning with that combo.

I'd vote cream as it's a great colour combo not that I'm biased as I'm going that classic look route Whistle 90 wolf - Jasmin http://www.defender2.net/forum/topic39408.html

Clayton, bizarrely I was thinking I've never seen that before, earlier. There's probably a reason for it.
