Is there such a thing as an upgrade for the 2.0 tdi auto transmission? Or a larger transmission like an extra gear or 2?

More curious about 2010-2012 wagons. Mine currently has 285,000 miles with lots of rust, looking to upgrade to something 2010-2012 from the southern states with a lot less miles. Fully delete it and if there's a transmission upgrade do that as well. I've had manual tdi's in the past that were great on mpg but I have become spoiled with the auto and the amazing reliability, 285,000 miles on the original trans

I think oil hammer was referring to the fact (and I'll use the 2 most obviously different) that there is a lot a variation for 2.0 TDI.

2005 Passat 2.0TDI = 134 HP PD with 5 speed slushbox automatic (oh, and longitudinal)
2009 Jetta 2.0TDI = 140 HP CR with 6 speed DSG (transverse)

Biggest upgrades for the '10-'12 CR with DSG would be software to change shift behavior, or swapping with another TDI that used different ratios. A lot of cash for #2 with questionable ROI

OK, your 02E DSG is fine as it is, there is no need for any upgrade. You can do some software changes that help the M-unit deal with any added power to the engine, if you have done that. But otherwise, the 02E is a pretty good unit.

Deleting should yield sufficient MPG improvement that you won't want taller gearing.... unless you drive on the Autobahn a lot.....

Ok thank you. Didn't know if there was a 7 or 8 speed transmission somewhere out there. My ecodiesel has an 8 speed and the new 1500 chevy has a 10 speed. I like how my truck at 85 on the freeway is around 2200 rpm. My car 2010 jetta tdi wagon at 85 is around 2800 rpm. I suppose I could slow down...haha nah

More gears doesn't necessarily mean better. And those 10sp slushboxes in the Ford and GM trucks do not even use all those ratios all the time anyway. They skip ratios depending on driving conditions, load, etc.

Your truck's VM Motori engine probably has a torque peak at a lower median RPM anyway, it has two more cylinders and a liter more displacement. It is also still a conventional slushbox (supplied by ZF), not a double-clutch type like the DSG. So it already isn't as efficient by design.

I have also noticed that a lot of the newer cars that have more ratios and a lower RPM at cruising speed tend to almost immediately require a downshift if ANY increase in load happens (slight hill, slight headwind, big bug hits the windshield, etc.). Particularly with gassers, though. But it is quite annoying, and they seem to be abandoning the manual-mode (like Tiptronic) so you cannot always override that nonsense either.

Mine is deleted and tuned, and transmission tuned to hold higher gears better. I had a 2015 jeep cherokee with the 9 speed auto. That thing only shifted into 9th gear when I was doing over 100 but it wouldn't hold it. My truck stays in 8th gear and rarely ever downshifts unless I'm pulling something.
That makes sense about the dual clutch auto that vw has though, I was always confused why chrysler products gives you the option to manually shift their auto but it doesn't hold the gear when its in manual mode.

Thanks for all the info!

My chick has a 2017 and the ratios on the 9spd are stupid tall..... totally the wrong setup for NA. I don't drive it a lot, but I doubt it uses the last two gears very often if at all....

Honda (Pilot) and now Nissan (the new Pathfinder) are also using the transverse ZF 9sp. Curious if they too are geared like that. Seems pointless to have so many ratios and never use them.

My Sprinter was a 7sp, and that G-tronic transmission was absolutely superb (and I generally despise anything I cannot shift myself). It used all its gears appropriately, at the right time, and once cruising at 80 it rarely ever needed to downshift, yet somehow it "knew" when you were pulling something heavy on the hills, both going up and down, when it needed a lower range.

5th is 1:1 and 9th is something retarded like 0.48
I don't know if they just messed up the final drive due to TC\diff combos, or ***, but I can tell you it's NFG unless you're trying to get arrested.

I went looking since we were on the subject.... found the "issue"

Canadian Specs said:
Gear Ratio
1st 4.71
2nd 2.84
3rd 1.91
4th 1.38
5th 1.00
6th 0.81
7th 0.70
8th 0.58
9th 0.48
Reverse 3.83

Axle Ratios
3.2-litre 4x2 — 3.251
3.2-litre 4x4 (non-trailer tow) — 3.251
3.2-litre 4x4 (trailer tow) — 3.517
3.2 litre 4x4 Active Drive II & Trailhawk – 3.517
2.4-litre 4x2 — 3.734 2.4-litre 4x4 (non-Trailhawk) — 3.734
2.4-litre 4x4 (Trailhawk) — 4.083

It is interesting to me how the "more gears, more better" thing has gotten to the point it has. Because modern engines seem to have a MUCH better overall ability to apply power over a much broader RPM band than they used to, even diesels.

I remember reading an article in I think Road & Track about the Porsche 911 turbo, that had "only" a 4 sp manual gearbox, when the regular non-turbo 911 got a 5 sp. The reason was, the engine made SO MUCH power over such a wide band that it really didn't need any more than four ratios. Fast forward many years later, and I actually was fortunate enough to drive one such beast, an '88 (I think this was known as the 930). And yes, four ratios were PLENTY. That car had zero problems getting off the line, the engine felt like it had immense amounts of torque right off idle, the mid RPM pull was flat and fat, and the top end zip once on full boost was astounding. Fewer gear changes meant you could keep your white knuckled hands gripping the steering wheel more of the time, that was was scary fast, and not at all refined like the later 901 cars. If an old IRS Beetle was a 2 on a scale of 1 -10 in refinement, this 930 was maybe only a 4. But the engine was a 13, LOL. Coworker's uncle's car, garage queen, but happily he let me drive it, and scolded me for being too easy on it ha!

Yap... more is better... just like you need every option.... I see lots of mall crawlers with lifts, snorkels, winches, bead locks, etc.... but not a speck of dust on them..... but I'm sure they get lots of show & shine points everywhere.

This. TFL tested(yeah, I know their tests are far from perfect) the Ram 2500 vs the Silverado 2500. On paper, the Silverado beats the Ram with 75 more hp, more low end torque, and a modern 10 speed vs the ancient 68RFE 6 speed slushbox. But their 0-60 showed it to be 0.2 seconds faster than the Ram, and the Ike Gauntlet towing test showed the uphill climb being identical, and better engine braking with the Ram down hill. I'm wondering if it's just poor transmission tuning on the Duramax, or bad drivers.

Back in the 70s I drove a lot of Mack semi tractors with the 237 HP "Maxidyne" engine with just a 5 speed transmission at weights up to 80,000 pounds... Worked fine, and was faster then the competitors with 9 and 10 speed transmissions!

I agree. This also means any time the power demand changes the transmission shifts, sometimes multiple gears :rolleyes: "Just pick a gear and stay there!"
