New 6 speed gearbox method - passat '11 onwards MYP gearbox

Just for balance, I had a nightmare buying a MYP last year, firstly I bought one from Northern Ireland which had liquid metal in it!!and didn’t even make it to fitting to the car the second was a dodgy reconditioned gearbox and had to return it for repair with even after this it was still broken. In the end I bought a second hand unit from a goof breakers and it’s been great!

Apart from MYPs (Superb / Passat 1.6Tdi), I've seen mention on here of the PTW (Golf, A3 1.6Tdi). A bit more hunting rustled up further codes for 6-speed gearboxes that appear to be the same 02S family of 02J-derivatives - QVX & RSD. Any thoughts on these as candidates (also 1.6Tdi variants) as more of these seem to be coming available in parallel to MYPs.

The MYP from the golf / a3 I believe has different ratios, the Passat bluemotion has the 2k rpm at 70mph

Just done a bit of a survey using 7zap's gearbox pages to knock up a spreadsheet (not much to do at this time of the afternoon) - having pooled some info from Audi A3 (8V model), Passat (2013-16), and Superb as well as the 75 & 90hp A2 gearboxes. Firstly it becomes clear that there is a huge amount of duplication and / or parts sharing, and in the last few years the MQ250 gearbox family expansion into downsized petrol engines has led to a lot of (in Tdi eyes) undergeared 6-speed MQ250 boxes out there (ie KWB, PPJ, QSZ, the Superb ones I found here other than the MYP shared with the Passat). Mostly down to the final drive. These ones can be largely ignored.

The table also confirms the MYP and PTW - which is actually slightly higher geared than the MYP owing to an interstellar final drive. The PTU is nigh on identical to MYP but there are some indications it is used with stop-start (questions over compatibility with a conventional starter?). Another interesting option is the MUJ box from the 1.8TSI Passat - same gearbox family, near-identical ratios (and part numbers) to the AMF/BHC from 1-5 with a full 6th, but a 10% shorter final drive meaning it is slightly higher geared in top than an ATL, at ~64mph / 2000rpm in top instead of 61 for the ATL. Would this be an option for sportier low end while retaining cruising capability?

This is a work in progress - when I find other boxes that seem interesting I will add them for comparison.

Hello. Have just taken delivery of a MYP gearbox. I am of course going to fit a new clutch kit. My question to those who have done this is do you need to use a passat release bearing or is the A2 one ok with the MYP gearbox?

Many thanks.

@GPW Please could you update your profile so we can see which engine you’ve got? Thanks.

Yes I think so but us chaps with TDI90s have DMFs so we’ve not got first hand experience with the BHC setup which has a single mass flywheel and likely different clutch.. I’m sure someone else can confirm soon.

Hi all,

So I've been doing some research on the 6 speed gearboxes mentioned by forum members as having been successfully used for / proved suitable for this conversion from experience, and what cars they can be sourced from - thought I'd share the below info taken from EKTA by one of the mods from another VAG forum I'm on for us all:

Suitable gearboxes that are known to work, from forum members' experiences so far: MYP, PTU, PTW, NTG

The MYP is fitted to 2 VAG models:

Manufacturer: VW, Date(s) Used: 08/2010-12/2014, Model: Passat/Variant/4Motion, Passat 1.6 TDI-CR, Transmission Code: MYP, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive) - <note that EKTA does not refer to BlueMotion, only 4motion>

Manufacturer: Skoda, Date(s) Used: 05/2013-05/2015, Model: Superb, Transmission Code: MYP, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)

The PTU is fitted to 2 VAG models:

Manufacturer: Audi, Date(s) Used: 02/2014-05/2015, Model: Audi A3 Cabriolet, Transmission Code: PTU, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)

Manufacturer: Audi, Date(s) Used: 02/2013-05/2015, Model: Audi A3/S3/Sportback/Limousine/Quattro, Audi A3 1.6 TDI-CR, Transmission Code: PTU, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)



The PTW is fitted to 5 VAG models:

Manufacturer: Audi, Date(s) Used: 09/2013-05/2015, Model: Audi A3/S3/Sportback/Limousine/Quattro, Audi A3 1.6 TDI-CR, Transmission Code: PTW, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)

Manufacturer: VW, Date(s) Used: 05/2014-05/2015, Model: Golf Sportsvan (SV) 1.6, Transmission Code: PTW, Transmission Type: 6S, Remarks: In 2014 an all-new successor to the Golf Plus was revealed, the Golf Sportsvan (SV), 02S Gearbox (front-wheel drive)

Manufacturer: VW, Date(s) Used: 05/2013-05/2015, Model: Golf/Variant/4Motion 1.6 BlueMotion, Transmission Code: PTW, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)

Manufacturer: Seat, Date(s) Used: 09/2013-, Model: Leon, Transmission Code: PTW, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)

Manufacturer: Skoda, Date(s) Used: 05/2013-05/2015, Model: Octavia, Transmission Code: PTW, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)



The NTG is fitted to 1 VAG model:

Manufacturer: Audi, Date(s) Used: 10/2012-02/2013, Model: Audi A3/S3/Sportback/Limousine/Quattro, Audi A3 1.6 TDI-CR, Transmission Code: NTG, Transmission Type: 6S, Remarks: 02S Gearbox (front-wheel drive)


Other candidate gearboxes which appear to be from the same "family" - 6 speed O2J / MQ250 - that I've not been able to eliminate as definitely not being paired from the factory with the 1.6 TDI engine are NBH, QWW and QBP - fitted to the Audi A3, Seat Leon, Skoda Octavia - same variants & years as where this model is mentioned above;

I've attached my version of the gearbox ratio spreadsheet provided by @Robin_Cox (Thanks Robin!) that contains the gearing information on all of the above proven candidate gearboxes, along with the standard TDI 75 and 90 ratios for comparison purposes.

Below is a comparison between the PTW and the MYP / PTU / NTG in terms of road speed @2000 RPM in each gear (smaller table); also what road speed in each gear at various RPMs a PTW-equipped car is doing, along with an estimation of the minimum desirable engine speed to change up into the next gear (larger table) for economical / relaxed progress. Both are repeated for slightly differing tyre sizes (standard and ~3% larger), for interest:

Conclusion: From this research - built upon the foundation of the many pages of this wonderful thread among others in particular - I'm now in the market for a PTW gearbox as a first preference; due to the longer gearing in each gear when compared to the other three 6 speed gearboxes when the different final drive ratio is taken into account.

I would think (hope) that the longer lower gears are going to enhance the TDi90's urban road manners: As can be seen, 1750 RPM corresponds to 20 MPH in 2nd, 30 MPH in 3rd, just under 40 MPH in 4th, 50 MPH in 5th and just over 60 MPH in sixth, meaning there will be a natural cruising gear for all speed zones (assuming free-flowing traffic anyway!): With the remapped TDi90's spread of low-down torque, I'm confident the car should require less gear changing in such conditions and return noticeably improved fuel consumption while reducing engine noise - both of which are my key aims for Merlin.

Possible drawbacks of this conversion (beyond the cost): I would say there are a couple of risks of having the engine turn at such comparatively low RPMs all the time:
  1. Dual-mass flywheel failure: I like to poodle around most of the time, however if I do want hard acceleration suddenly whilst doing so then instead of just putting my foot down, I will just need to ensure I always change down first to avoid hard shocks from the individual firing pulses being transmitted to the DMF. However, I think for normal acceleration scenarios I will just train myself to be careful to gradually feed in small amounts of throttle to accelerate with mechanical sympathy / until the revs have crept up to 2000 or more. Merlin also has a new DMF and clutch already, so one less thing to worry about for many years either way;
  2. Coking up of the engine: I read somewhere that these engines need to be turning at over 2000 RPM under a good load to get hot enough to blow out any soot build-up internally - Not sure whether this is true, I'll just need to bear in mind the car will need some welly on the motorway occasionally from now on (or just cruise at 75-80 occaisionally). I also plan on using the Miller's diesel additive, I'm pretty sure this will eradicate any risk of, for example, gumming up the variable vane turbo with deposits.
  3. Driveability:
    • Assuming I will always cruise in the highest possible gear for the conditions / speed limit, it will be interesting to see whether the slow RPMs become a pain in situations where traffic is moving at continually changing speeds at / below the speed limit - Will I need to change down, or will the car be happy to potter along at reduced speed / revs until acceleration is needed? It would also be interesting to hear from TDi 75 owners who have fitted a PTW as to how driveable the car is in these scenarios, then compare this to TDi90 owners’ notes who have done the same. Currently I suspect the MYP / NTG / PTU may be more suited to the 75 while hopefully, the PTW is the best choice for the 90 as the torque comes in at lower engine speeds - We won't know until we get more owners of both types converting to PTW and posting their notes here;
    • The first gear change-up point into 2nd seems high - I have assumed that the absolute minimum you could get away with is changing up at 2600 - 2700 RPM, which will feel a bit wrong on a cold engine I would imagine!

EDIT: I've just found a PTW 'box and starter motor from a breaker on eBay in Cornwall from a 2013-16 Seat Leon 1.6 TDI with 35,000 miles on it and bagged it for £475 delivered! Now on it's way to my restoration / restomod specialist of choice! Also I've found a good used Audi A3 Sport 6 Speed Black Leather Gear Knob (part code 8P0863279) for £9 which I'll use as a donor for the six speed gear knob emblem for the car's current gear knob for that OEM look!

From this research, I'm now in the market for a PTW gearbox as a first preference due to the fractionally longer gearing, which as I'm planning to buy a re-mapped TDi90, I think will be ideal.

Would this not be better posted into a new thread, rather than one that is specifically about fitting the MYP box?
 
I wouldn't have thought yet another new thread on the 6 speed conversion using other 02J / MQ250 gearboxes is desirable, especially as the point of my post is directly related to fitting the MYP (as in, there is now a confirmed wider choice than just the MYP, hence you do not need to be restricted just to this), but up to the mods I guess.

The NTG is fitted to 1 VAG model:

I've also attached my version of the gearbox ratio spreadsheet provided by @Robin_Cox (Thanks Robin!) that contains the gearing information on all of the above proven candidate gearboxes, plus I've deleted some of the 5 speed gearbox lines to leave just the standard TDI 75 and 90 ratios for comparison purposes, and added some additional calculations to take into account different tyre sizes, various RPMs vs MPH scenarios in each gear etc. to make it more useful.

Conclusion: From this research - built upon the foundation of the many pages of this wonderful thread among others in particular - I'm now in the market for a PTW gearbox as a first preference; due to the longer gearing in each gear when compared to the other three 6 speed gearboxes when the different final drive ratio is taken into account.

This is particularly so in the lower gears, which as I'm planning to buy a re-mapped TDi90, I think will be ideal to avoid too much cog swapping around town - Here is that difference in each gear, expressed both in actual MPH at 2000 RPM and as as additional % over the corresponding gears of the MYP / PTU / NTG, which are more or less identical to the corresponding gears of the standard TDI 75 (up to 5th gear of course):

View attachment 66294

I would think the longer 3rd gear in particular is going to contribute to this upgrade nicely in terms of urban road manners: 30 MPH will correspond to about 1700 RPM, so there should be less gear changing required around town in freely moving traffic (I don't accelerate quickly in this type of environment), with the taller lower gears nicely matching the remapped TDI 90's spread of torque low down - thanks in part to it's variable vane turbo.

Whilst in top gear with standard or slightly taller tyre sizes the revs would be as follows:

175/60/15, 1857mm circ. (Std): 1998 RPM at 70mph vs the 2028 RPM with the MYP
175/65/15, 1910mm circ. (Std +3%) 1940 RPM at 70 MPH vs 1972 RPM with the MYP

Hi dj_efk

If you have the old 5 speed sport embilum I'd be interested if the chrome is good? Upgrading mine and the one I have is terrible.

Thanks
