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

Dogbrain said:
Hey, guys.
A stupid question here.
Is a MYP gearbox always the MYP gearbox or do they have modifications according to cars they are installed in?

If it is an MYP it is an MYP of identical specification whether in a Golf or a Passat. Same with PTU, NTG and PTW regardless of the vehicle it is installed in (Golf, A3 etc).

There were a couple of posts in the 6-gear threads a year or two back that insinuated variations in specification for gearboxes with the MYP code in different vehicles but I'm reasonably certain that was a mistake as I've not been able to identify differences in spec in the 7zap pages - and consequently it is a myth that needs to be bust rather than propagated.

Correct Robin, a MYP is a MYP (or a PTU or a NTG) - for our purposes all three are identical regardless of source (and practically speaking, interchangeable with each other).

The PTW as you well know, is identical externally and in terms of fitting, but with longer ratios that make it slightly better-suited to urban environments in particular in my opinion - and is therefore the one to have if presented with a choice.

Any of the four codes is a huge upgrade to high speed driving mind

When I mounted the PTU gearbox on my 1.4 TDi BHC, I noticed that the interference between the starter motor pinion (Valeo 02Z 911 024 L from the original car of the PTU gearbox) and the flywheel ring gear was not correct in the direction transverse to the vehicle. The starter motor pinion only rests 2.5 mm on the flywheel ring gear. After some measurements and investigations, I discovered that this is due to the fact that the bell of these gearboxes is 5 mm longer to accommodate the dual-mass flywheel. The objective was clear, remove 5 mm from the plane of the starter motor. After a brief visual study, 5 mm seemed too much to me as I had the risk of drilling inside the starter motor, so I ordered the machine shop to remove only 4 mm. After receiving the starter motor, even with these 4 mm, a small hole actually appeared in the casting of the starter motor housing, but nothing serious.
...
I also considered the option of a starter motor 5 mm longer from a 1.2 TSI but this starter is only 1.4 kW of power (sure enough for the 1.4 TDi) but I preferred to keep the original 2.0 kW A3 since it starts the motor very fast and with an nice sound (original Bosch BHC starter is 1.9 kW).

I am considering putting a MYP etc. in my 2002 1.4 TDi with single mass flywheel. My understanding is (providing the speedo drive isn't on my gearbox - need to check) that it is a reasonably straightforward swap just needing a couple of cable brackets fabricated. From reading this thread, I believe these gearboxes were coupled with DMFs and have a slightly extended bell housing? @miguel_e38 for his BHC, with PTU starter, he noticed the pinion/cog doesn't engage far enough. Does anyone know if this would be an issue with an AMF engine/flywheel?

I have an AMF with NTG box, and a BHC with PTW box. The same replacement starter motor was sourced for both - sometimes referred to as the "CAYC" starter motor it can be sourced from various 1.6Tdi stop-start vehicles such as the Q3 or Seat Ateca from 2013-2020 or so. Part number 02Z911024L - neither of mine cost more than high Ā£20s from an Ebay breaker - I went for starters claimed to be from cars the latest date possible and with reasonably low mileage that also looked good and clean in the photos - there are some horrible-looking starters for similar prices so I thought it made sense to go for ones that looked ok.

The NTG box was machined down 6mm to reduce the DMF bell housing to suit the SMF. New LUK clutch kit.

The PTW box was fitted exactly as purchased without machining. New Borg&Beck clutch fitted.

They both work - NTG is a tidier installation by WOM, the PTW swap was done very cheaply by the mechanic at the end of my road 2 years earlier during Covid. Occasionally at idle there is a rumbling / clattering noise similar to a release bearing, but I suspect that may be due to not shortening the bell housing - the quality of the change and bite of the clutch is completely normal.

Hand on heart I probably prefer the feel of the PTW for everyday use - the higher gearing matches the torque curve on my BHC perfectly and with cruise control it trundles along at around 2100rpm in 6th nicely for long distances on the motorway. The NTG is paired with an AMF that has a slightly different tune on it, and it gets stronger the higher up the rev range it goes, particularly building between 2 & 3,000rpm. Real greyhound at ~70mph.

Besides the two cable carrier brackets needed to fit, you also have to swap the driveshaft cups over from your original A2 box to the new one as the A2 cups use larger diameter bolts to secure the driveshafts than the more recent donor cars (it's either M10 compared to M8 or M8 compared to M6 from memory).

Is the bolt pattern the same however? As Passat bolts could be sourced?

the bolt pattern is the same, just the bolts and holes are larger on the A2 cups. I still have the old golf bluemotion cups sitting in my scrap pile from the first transfer - I suspect they and Passat bolts are identical. However I'm not entirely clear on why you would want to use Passat bolts : they wouldn't fit A2 driveshafts - am I misunderstanding something?
 
Borg and beck clutches are well known to rattle at idle, so I suspect it's the clutch and not lack of removing 6mm. Great that it can be bolted straight up

If itā€™s not LUK or Sachs the. My conclusion is you risk a sub-optimal result when it comes to A2 clutches

I have a couple of Valeo ones fitted to ours and touch wood they seem fine. Also have an AP one in stock but this looks like it's actually Sachs if memory serves me correctly!

I'm also very interested in this question =)
Does anybody know if all these gearboxes (MYP, PTU, NTG and PTW) will fit the 1.6FSI?
:)

Iā€™m not at all sure really, since the gearing needs to be completely different to get the best out of a petrol engine with a higher redline than a TDI. It depends on what you want to get from the swap too, (less noise on motorway, better use of torque, better economy?) and you need to check out the range of ratios before and after any contemplated swap.
Iā€™m not saying it would make sense or be in the least feasible, but how about comparing to GUU gearbox fitted to Mk5 Golf 1.6fsi from 2003?

Hi All. Im having the clutch replaced (with an LUK this time) on my A2 (AMF engine with an MYP gearbox). Im wondering what the part numbers for the clutch release fork and clutch release bearing are? Im supposing they are the parts for a 2011 Passat 1.6 tdi bluemotion (which the MYP came from) ? Are there other parts needed e.g. a pilot bearing, bearing guide tube?
Thanks
Nick

Defo the top hat that the release bearing slides on and the spring clip for the fork arm and the ball ended bolt it pivots on
