5-speed transmissions for T4 TDI
I done a lot of research for last half year or so... with Eurovan TDI project in my mind... 02B - was only available 5-speed, not 6-speed. So as far as I know, 02B transmission (type of the transmission) was installed in 92-95 Eurovan (in Canada and US), 1992-2002 in T4 Transporter/Caravelle (in Europe). In US models Eurovan 02B transmission only come with code CHP - and this is short geared transmission and will need to modify it to be perfect geared for diesel, othervize your engine will rev high at freeway speeds...
European T4 Transporter was available with a lot different geared transmissions (probably 20-25 different transmission codes), but also even if it was installed in diesel T4 - most of them they are not geared as good as we want (will be high RPM's on cruising speeds) because they was made to work with diesel and some with turbodiesel, not for TDI. Best options if import transmission from Europe is to get transmission that was installed in 1998-2000 T4 2.5TDI, with codes: DUH, DUJ, EWA and EWB. They are perfectly geared for TDI, actually DUH/EWA will be perfect for tuned 1.9TDI and DUJ/EWB will be perfect for hawy tuned/modified (like stage 4-5) 1.9TDI. I was looking for long time to buy and ship any of this transmissions from Europe, but so far NO LUCK. Firstable whey are highly priced outhere (germans/brittans also installing this transmissions in older T4's), and second most important - no one willing to ship transmission to USA, (believe me). If you find one and with shipping you end-up around $2000 - you are get lucky.
There is an other option, and so far I think its cheaper. Order 4.23 R&P (ring and pinion) for 02B and install it in US gas Eurovan transmission (code CHP), it will lower total RPM's in all gears by 8.1%, and it will be not bad. But I never replace R&P in my life and I think its not very easy because will need teardown transmission completely, and will need special tools (not sure). In additional to installed taller R&P possible there is an option to swap in slightly taller 5th gear (5th gear is the same style in 02A). With mine calculations - if swap 4.23 R&P in CHP and 3rd and 4th gears from CTN (B4/MK3 TDI) and custom 5th gear .681 - it will be almost identical transmission to DUJ/EWB. But to do that job will need some skills with transmissions, or sent it to transmission rebuilders (that is not cheap)...
Justin (caddywompus), correct me please if I am wrong in any of the info above.

So
what car(s) is(are) the 02B available in? is it a 5 or 6 speed?
I have an 03 VR6/01P GLS Eurovan that would be PERFECT with a TDI/5 speed in it...
