The box is pretty much in - can let you know how the ratios work early
next week (I hope. Poor Warren has not had an easy time of this job).

In case you were away sunning y'self, there's a little spreadsheet to
help work out the ratios here:

Flipin 'eck now thats what I call a good answer


Will be get the piccys of the work? And now Warrens perfected the art I may
just call on him in the future

is this the auto conversion?

which configuration did you opt for in the end?

ZF 4 speed (yes, I know the 3 speed is prolly stronger, but I got a
_very_ good deal on a blinding quality 4 speed...) Transfer ratios as
per the spreadsheet. I opted for a geared transfer box mainly because
there's more flexibility when looking at ratios whereas the Borg
Warner is fixed. The BW also suffers from chain stress, which'll
stretch...

In a 101 this is noooo small conversion. Heat is an issue as the
torque converter generates a lot of it. I thoerefore got a 44 row
Mocal oil cooler - the biggest I could get quickly. They can do 50
and 60 row coolers, but I thought that'd be overkill ;-)

The props will need changing, but I'll have some made once Warren has
worked out the exact lengths. Here's the nifty bit... With a little
careful mounting you can actually reduce the very steep angle of the
props (common cause of overrun rumble on a 101).

It's possible (well, Warren has done so) to use the existing gearbox
mounting brackets, however an LT95 sort of 'hangs' from the mountings,
where the ZF sits on them. Warren has made some awesome dogleg
brackets (strong enough to hold an aircraft engine by the looks of
them).

The auto shift and hi-lo are on the front where the handbrake and old
hi-lo were sited, oil cooler just in front of the rad and engine oil
cooler (s*dding good job we've cured the overheating!). Kickdown
needs an adapter plate making, hi-lo ratio and difflock will be on one
lever as I figured I've never used difflock in high ratio and (mostly)
use difflock when I need low ratio - I know this may have a few
downsides, but it's good enough for my pattern of use over the last 25
odd years.

More to come...

the ZF gets good reviews as well, and is used to transmit some serious
amounts of power in other applications.

Longer box/bellhousing combo I assume, moving the T-box back?

wonder if you'd do better using RR style ZF mounts? The mounts, of course,
go on the T-box not the actual main gearbox.

what fuel system are you running on Grumble? I'd've thought the kickdown
linkage was available from some species of Rangie, as stock parts. The ZF
auto was certainly fitted to several kinds of injection engine. Not quite
sure about a carb one. Mind, I've somewhere got the linkage I used on the
3.5 carb engine, which came off a Rover P5B auto, and was modified to suit.
If you're running a normal carb manifold, you're welcome to it if you want.

The ZF is a great box. Mine comfortably handles the 280-ish bhp that my
130 throws at it and it does a *lot* of heavy towing. The secret is
keeping the fluid temperature down (with a decent cooler) and to most
definitely use a fully synthetic ATF (I use Redline). Even so, it does
generate huge amounts of heat!

I have a spare ZF box (and 3.9 EFI engine) and I'm seriously contemplating
this conversion in my 101, so I'll be interested to hear how your
conversion materialises. What transfer box are you using, an LT230?
