Got to wondering about this recently.

Between the panel van and Caravelle 6 speed models is there any difference in the gear ratios?

And is there any added differences by the 4motion though I doubt it

I find first and second very short in my manual 2007 T5 4motion.

When the box failed in my shuttle I originally hunted for the same code (GWB) but was told by Kernow transporters all the 6 speeds have the same gear sets in them, the only differences are that principally bearings were upgraded in later boxes to make them stronger. Don't know if that includes 4 motions or not though.

4 Mo often have 51-13 (3.9:1) first gears, 2WD are usually 50-14 (3.5:1). There is also a short range 4Mo gearbox with the code JFX and JFW in 2007

Thanks, thats interesting.

I suppose theres some logic to it but theyre frustratingly short ratios, even loaded. Il check the buld codes and see, cant imagine worse news than the close ratio box, doubt thats the prob though 3 to 6 are normal VW or feels like anyway,

I have a 2006 2.5 4Motion 6-speed & yes 1st is very low, but these are heavy vans to get rolling,& v useful when towing or on very rough tracks (foot off gas, let the 4mo do its work). Not good for tearing away from the lights, but wouldnt buy a T30 for that anyway. Just change up quickly into 2nd. 6th gives a comfortable 80-90mph on motorways (I mean autobahns, of course). Wide range on 4th & 5th. This gearing feels pretty good all-purpose to me, but it's subjective. May feel odd to someone at first but you learn to get the most out of it. Like the size - friends ask how I manage on these tiny country lanes, but the height, visibility & great mirrors make it easy. Easier than my wife's 2door Toyata RAV.

Im very used to vans, Ive driven them a lot of miles over the years :)

What I mean is I found 1st short even for a van, must be the shorter 4motion ratio, thanks for that info. I had a T5.1 LWB for a work van a few years ago and it didnt seem so short geared but it was a 2WD.

Just as well most of the box is the same, I did a lot of miles this year, and though 30 - 40 mpg isnt terrible for a van, more would have been nice. :)

As I said the rest of the box is fine, and tbh with the BNZ in the 4mo youll get more than 80 - 90 even without a remap. :)

Generally on a VAG TDI 3rd is the main gear for most of the acceleration, then quickly up to 6.

If you drive a lot of different vans, as I do, and have, you will appreciate how maneuverable and easy to handle the Transporters are compared to most, and just how sure footed and trustworthy they are for grip and handling compared to most of the competition, even new equivalents now.

I've been looking for this information as well, what I've been able to find is in this document here. This info is for the facelift vans with the 2.0 CR TDI though I believe. I haven't been able to source this info for the earlier T5s.

It doesn't give gearbox codes, but in order of kw/bhp: (first two are only 5 speeds)
62/83
i Gang 1. / 2. / 3. / 4. / 5./ R.
3,78 / 1,94 / 1,19 / 0,82 / 0,59 / 3,60
Ring:pinion = final drive
i Achse 74:15 = 4,933

75/100
3,78 / 1,94 / 1,19 / 0,82 / 0,59 / 3,60
Ring:pinion = final drive
i Achse 74:15 = 4,933

103/140
i Gang 1. / 2. / 3. / 4. / 5./ 6. / R.
3,92 / 2,05 / 1,70 / 1,09 / 0,82 / 0,68 / 4,95
Ring:pinion 1 = FD for 1st-2nd
i Achse 1 69:15 = 4,60
Ring:pinion 2 = FD for 3rd-6th
i Achse 2 69:21 = 3,286
Ring:Reverse gear = Reverse FD
i Achse R 69:19 = 3,632

132/180
i Gang 1. / 2. / 3. / 4. / 5./ 6. / R.
3,92 / 2,05 / 1,75 / 1,16 / 0,86 / 0,73 / 4,95
Ring:pinion 1 = FD for 1st-2nd
i Achse 1 69:15 = 4,60
Ring:pinion 2 = FD for 3rd-6th
i Achse 2 69:21 = 3,286
Ring:Reverse gear = Reverse FD
i Achse R 69:19 = 3,632


The interesting thing about this is that with the 6 speeds in the Jetta/Golf/Beetle, the 02m gearboxes, the split between 4th and 5th isn't quite as big. in the 02m there are three shafts and 1-4 are on the first final drive, 5-6 and R are on the second. Interestingly based on the SSP document for the 0a5, it uses four shafts. It appears that 1st and 2nd are on one shaft with the first pinion and ratio, 3-6 are on the second and reverse is on it's own.


This table shows what speeds you would have with the tires I have for my van right now, I still want to swap in a T5 gearbox so that I can use this info.



This is a graph of the top gears and speeds of some different gearboxes that I've been looking at for my swap. The 02m DRW was what I had in my MK4 Jetta TDI that I swapped a european 6 speed into. That beast made it to 350k miles and was still getting me 50+ US MPG. I'm hoping with the top gear ratios below it will help the van with MPGs. The tires I'm putting on my van are bigger than stock, so a stock sized tire will be slightly slower/have a higher RPM. I doubt we'll get 50mpg, but anything over 30 will be pretty awesome.

I have a 2010 T5 4motion. Okay car, but damn i would like first gear to be 0.5 instead of 1.
stupid meaningless high ratio on first.
Doing new clutch at the moment and i will propably do it again and again and again. Nice for delivering goods along the city curbs. not so good pulling and reversing trailers on hilly lands
