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

Oneill said:
Guys,regarding the speedo drive.
Is there anyway of getting a signal from the abs/speed sensor wired into the clocks?
I’m a mechanic and I’m going to go with this 6 speed conversion for both of our a2’s,but I need to know if it’s possible.
Thanks and keep up the good work

Another way would be to use an electronic interface. I assume the gearbox has a reluctor ring (or actually a gear’s teeth) and the sensor is the reluctance type, or else the gearbox has magnets and the sensor is a Hall type. If one knew the number of teeth or magnets on the gearbox speedo “drive” and the same for the ABS reluctor rings, then it should be possible to do it with the required level of accuracy. The most flexible way would be with an Arduino linked to suitable interface circuits on input and output. Another way would be with a linear frequency-to-voltage converter circuit driving a voltage-to-frequency converter to give the right multiply or divide factor.
A fair bit of trial and error would be needed, and if I had the time I’d offer to help.
There is the advantage that no new gearbox has to be bought or fitted before a custom electronics converter box is proven.

The MYP in my A2 1.4TDI BHC was replaced with a PTW gearbox from a Golf VII 1.6TDI BlueMotion. Besides, a Quaife QDF26R limited-slip diff was installed as well. Looking forward to driving my car:)

I'm thinking of sticking in an MYP and saw your recommendation for a PTW. How did your swap go? Do you still have to make the brackets for the gear change mount? Currently there is a PTW on ebay cheaper than an MYP!
 
I looked into this some years ago
I believe there are six magnets on the gearbox diff ring that actuate the hall sensor used for the Speedo drive
This can be easily proven by connecting a dvm to the sensors locking up one wheel and rotating the other through one complete turn and count the pulses seen on the dvm

My plan was to 3D print a ring to fit over an inner cv joint that would hold 6 neodymium magnets and then mount the original Speedo hall sensor such that it would read the magnets
Speedo Mary be a little off when turning sharp corners but would be good enough for all practical purposes

I never progressed the idea because affordable myp gearboxes are like hens teeth so I went with the long 5th gear instead

This can be installed without removing the gearbox which for me was a major advantage

Thanks for reply Paul. I should have made it clearer. The engine and geabox are currently out of the car in my garage whilst doing a DMF change amongst other things. Its an 05 reg atl so I think the speedo drive is not an issue?? There is lots in this thread about MYP swap and I am confident I could do that. I saw that Bala de Plata was suggesting a PTW box. I checked out the ratios which would be ok but there is no detail whether the PTW box would fit in the same way as an MYP ie brackets for gearchange? I was only curious as there is a PTW box on ebay cheaper than a MYP.

I can't decide whether to bother swapping to a 6 speeder. Obviously it is relatively easy while the engine and gearbox are out of the car but I never drive on the motorway (mostly 50mph roads and town driving). The snag is that this will probably end up being my sons car in a couple of years and he no doubt will drive everywhere in it, as we all did with our first cars. I was trying to convince myself that it might have a better gearchange (my A6 C6 gearchange is like silk) but then the additional £400 (for the PTW on ebay) on top of about £1000 to put this car right starts to niggle at me.

If I was reassured by the wonderful collective knowledge on this forum that the PTW fit in the same way or even easier than the MYP then it might tip me into doing it, otherwise I think I will leave it be for now.

As you can see I'm a rambling emotional indecisive wreck with this rescue.

Hello everybody,

I'm realy interested on the conversion of my a2 ATL(90hp) in to a 6 speed gearbox, and I saw there are many possibilities, using the gearbox models: myp, ptw, ptu ... and maybe others.

Can somebody's let me know which gearbox is easyest to mount : with minimal intervention ? And also what gearbox is the most apropiated (in terms of transmision ratio, weight, etc ) for my TDI 90 hp (ATL with Dual mass flywhell)

Thank you very much for your time.
 
I'll bet it will be a decent amount of intervention no matter which box you go for, there are kits for converting current box to 6speed but you'd need to essentially rebuild the gearbox.

Either way my understanding is unless you're comfortable chopping metal and possibly welding some bits it's better to steer clear as with most projects there will be eye balling, wiggling and chopping to make things fit, that or drop it off to stealth (i believe it was stealth?) to do it for you.

I am tempted myself however until i move and have luxury of a decent driveway and garage with spare car i wouldn't tackle this, and at that point electric conversion might be a really good option for both performance bump and making trees happy.
 
Thank you for your answer,

I can not saying I'm happy with cutting drilling or welding metals but I think I can doit at a certain point,

Please can somebody explain the necessary "adjustmen", (step by step if possibe ), especialy on the gearbox (I suppose there is not necesary to have changes in the engine block), fot MYP and also fot PTW/PTU ( if there is somebody that install that PTW/PTU gearbox).

Olerype, why do you think is not good to run ATL below 2000 rpm ? In my opinion the best confort (noises)/ comsumption / torque on flat is when I run on between 1800-2000 rpm, but on highway I need the 6 gear other ways is to noisy

Thank you again for your help!

I have a MYP with the ATL you will need to make the bracket very simply. You will need the starter from the MYP and you will need to remove the spacer which is used with the standard box, you will also need the driveshaft cups from the old box. All quite straight forward no modification to the box is required. A remap is worth it also.

In the flat I can do 1500rpm at 50mph smoothly in 6th but it won’t be happy on an incline 2000rpm is 7mph with the myp and it will be happy above 1900ish

Thank you Edwrai, seams to be really easy that modification, and realy full of benefits on having 6 th, much easier than I expected, the only think I don't understand: what do you mean with "driveshaft cups"? (And try to find a picture on google but I'm not sure I understand right, are the flanges between the differential and driveshaft?

i am guessing it is the flanges that bolt onto gearbox and go to the drive shafts.
 
Yes, that’s right. They are splined flanges held into the gearbox by a single bolt which has a Allen head and often covered with moly grease. The reason you have to change them is because the 6 bolts which attach the driveshaft to the flange are M8 on the A2 gearbox and driveshafts and M6 in the MYP (at least, so far as I recall).

I think that there is a major plus with fitting the Passat MYP gearbox and it may not be fully appreciated. (I recently drove an A2 with this box, you see) I have the Eurotuning conversion. So what I observed was a MUCH superior gear-change action. Shorter throws and a much smoother action!
So that's the one to go for!

Sorry, should have been more precise; flat/coasting slighty below 2000rpm is ok; but accelerating below 2000rpm is normally not so nice for the dual mass flywheel. At least my ATL express that very clearly

Accelerating any more than part throttle below say 1900ish is not nice no, also my turbo gets a horrid blow back noise in these conditions as the engine can’t use the boost... but you learn to drive it and it’s great. It can handle low revs in 6th In very certain conditions! But yes the cat wants to do 2k+ if WOT

Thank you very much all !

Now I have to find one good MYP, :) good to know that about the RPM, especially before making the modification, now I have to count also with this.

I also have a question ...In some day I also think in installing the Cruise Control, If I go with the MYP is possible to have some problems on functionality of Cruise control ?

Also will be great if somebody who mount or have idea about the PTW/PTU gearbox can have some opinion...

Best regards!
 
Cruise Control is completely separate and should be fine to install later. I had cruise on mine before the MYP and it operates just the same now.

Yes, cruise control below 2k rpm in 6th isn’t good as it can use too much throttle for the rpm, so in 6th don’t use cruise below 70mph

Just adding my bit in ....

my ATL engined tdi , has for the last 20k miles used the Myp gear box , which was fitted by WOM autos , marquis and rob have carried out a few of those gear box conversions , I would say my car was in for a engine out rebuild at the time of the gear box upgrade , so the costs was mainly the gear box , from eBay

my notes and “feelings “:are ,

1. the gear change is very much shorter , even more so , as I have fitted a TT gear knob
2. my car has a remap , and is providing 270nm of pulling power , this matches the gears ratios very well , six gear is best used on the faster roads / motorways
3. on the flat , with Cc set to 56 mph , it’s is very happy in 6th
4. 70mph , with 205/45/17” tyres is bang on 2,000 rpm
5. the spacer plate was removed between the gearbox and engine
6. the starter motor was reused , it is, a very tight fit under the gear change tower
7. MPG improvement, very hard to say , as the engine was shot before my gear box was installed , I do see the following on long runs on motorways upwards of 80mgp , round town mid / short runs kids 50s , faster A/B roads upper 60s mid 70s mpg

the myp gear box’s , are available, and more so as the base vehicle gets older / written off etc

I would add this conversion works very well , in my case mainly motorway driving with long journeys at 60-70 mph speeds

If any body wants to go for a short test drive in Derbyshire, drop me a line and we has a trip down faster B roads and the m42

I will also post a video of my journey to the office , this being a 10 mile , town / county run , with a faster 4 mile bit when the cars warmed up

regards
