This is just a final 'thank you' and a goodbye. You'll be pleased to know that at last I've solved the challenge of obtaining the required highway gearing on the 6WD Volvo. The answer is to run an Aisin A465 six-speed double overdrive automatic gearbox with a 0.63 top gear ... unfortunately...

Picture this. Foreign driver, foreign truck, steering on the wrong side (LHD), driving on the wrong side of the road (RHS), surrounded by traffic density you wouldn't believe, lost, well-meaning handbrake shouting instructions (late), and grabbing for the appropriate gear with the unnatural...

I don't know about space in the drop box, but the gears themselves are straight cut. Major problem would be the internal splines on the larger gear. I'm not sure I agree about a ready market for higher gearing. I don't think enough C-series were produced and it's only a few diehards like...

Yes Dougal, the axles are the same as in the photos on your link. I believe all the Volvo C-series axles are the same, except for the location of the diff on the third axle of the 6x6s. The first and second axles have right-side offset diffs (as in the 4x4) but the third axle diff is...

O.K. for those still interested, after all the research here's where I've arrived. With the highest available diff ratios for the Volvo being 5.99, I'm forced to adopt what I've learned is called 'double overdrive' to achieve around 2000rpm at 100kph cruising. Around 0.7 can be achieved...

35" standard, up to 37" legally.

Finally sourced the 'big picture' from Ashcrofts. As I thought, there's insufficient space in the TL230 to accommodate overdrive high range gears. On their idea of adding an overdrive, when I mentioned it would go behind a torquey 4 cylinder diesel engine pushing 4.5 tonnes GVM the answer...

Jeez Dougal your approach is becoming increasingly radical, I guess in response to the deepening hole in which I find myself. I really like your lateral thinking but haven't even thought about that approach, and for the time being I'm refusing to do so. The trouble with trying to plan that...

I'll ask, but I'm pretty sure I read somewhere there's not enough space in the case to accommodate a larger gear.

Ashcroft say they don't do the LT230 in overdrive high range. I'll see what Gear Vendors can offer. Thanks Cicak for the lead on Dave Metcalf. I think your torque warning on the Volvo axles is a little askew. You believe they're only rated to 205Nm ... yet the standard engine produces...

Thanks specifically Dougal and Longbow for all your input so far. You're comment Dougal regarding the Series transfer case strength has only increased doubts I've long held about its potential durability behind a torquey four cylinder diesel. Anything LR really! A year and half planning...

As they say, "an afterthought is better than no thought at all". Just looking through my photo files before bed and spotted a Toyota 14BT. Does anyone know if the 14BT or 15BT will bolt straight up to an A440F. Then I'd just need one adapter ... transmission to Series transfer case...

By the way, manual transmission is not an option. Professionally I shift 18 cogs in B-doubles, but not when you're tootling along seeing the world. I'd be keeping the Volvo LHD to suit most of the countries we'd be travelling, and auto allows much more time for concentration on the...

I agree the 4BD1T would be a simpler, and probably safer bet than the 4HE1TC when driving through a Series transfer case. Really it was just hopeful thinking on my part. So, let's assume I've settled the engine question. In a perfect world I'd run the same make of engine/gearbox/transfer...

Thanks for the quick response. Saw your adaptors but still deciding which driveline package to settle on. Regards the HE1TC, I would run it in the lower manual transmission state of tune anyway. But if it could indeed keep running indefinitely in 'limp home' mode after any computer crash...
