Six Speed Trans Options

[adam.nonis]

I am just going to run the GS6-17 for my swap (I don't need huge power), but when looking to source one I'm seeing GS6-17DG, GS6-17BG and GS6-17FG

What's the difference? I'm not a native BMW speaker, but I'm taking courses, so be gentle. LOL

The GS6-17FG was used by 2016-and-later 4-cylinder gasoline BMWs (F20, F21, F22, F30, etc.).
The GS6-17DG was used by 2016-and-later 4-cylinder diesel BMWs (F20, F21, F22, F30, etc.).
The GS6-17BG was used by E8x, E9x, E6x models up to 2013 that were equipped with the N52.

Perfect! You're the best

Donkeyshins, so those gearboxes will bolt up ok to the n52? I'm new to this motor and am curious. Do any of them have a removable belhousing?

Reason being is I'm assessing some options for a build I want to do.

My assumption is that the 17FG and 17DG probably won't bolt up to the N52 as they were designed for the N20 and B47 respectively (unless the bolt patterns are identical, but I have no idea).

This is correct. If you go on eBay and pull some up you can see the bellhousing shape is wrong.

Nice to see that for once, my assumptions have paid off. ;)

I think it would be helpful to have more information. I was thinking about starting another thread with this info, but honestly until I can make more progress myself, I'm just here to provide the info I can.

On my wishlist is to make a large how to document this swap with potential options (as usual with way more info than necessary, but some may find it helpful.)

This project will require data from others, which will be some of the info below, but with specific data for each setup, and options if they exist.

================================

There are probably ways to make other transmissions work (reading z4 forums about drilling etc) but I know the two below are in running and driving N52 swapped E30s.

[downforce22]

what driveshaft do you need with the -17 trans? Can you use a regular e30 shaft?

That looks right. Just the “big boi” one. The easiest way to tell is the starter location. The extra bulge in the bellhousing

E30 shaft will not work. -17 uses the larger guibo. I don’t know what combination of shafts will work. I just ordered a custom shaft.

[projectJTv4]

Just to add to the list, I pulled this from a 2006 330i in the US.



Per VIN / chassis code (VB33) on realoem, it is 23007565853 / GS6-37BZ - TJEP.

I don't see any obvious stamping or labels with these numbers though.

[Maxhouse97]

Are they any 5 speed options that will mate to a N52?

I think it would be helpful to have more information.

I wholeheartedly agree. Can you update your post with this information:

adam.nonis has used a driveshaft from 2004 BMW 325i (M54) auto trans 1373mm/GM5 #26111229565 (PDL/API #1701-719434) for a GS6-37BZ-TJES (#23007565178) out of a 2007 Z4 3.0si (E86) per his build thread.

The trans is out of a 2007 Z4 3.0si (E86)
GS6-37BZ-TJES (#23007565178)

Exciting news. The complete driveshaft from an E46 325 w/GM auto trans is almost a drop in. Differences are the “nub” height of the diff flange .2” for the E46 and .1” for the E30. Easy enough to just grind it down. The control surface is the OD, so you can just do this with a grinder.

And carrier bearing placement. I'm building a “clamp” setup, but it probably could be solved multiple ways. In the pic it still has the E46 CB, but the E30 CB swaps on (doesn't help bolt location, but fits).

Striker01 has used a custom driveshaft from https://www.driveshaftpro.com/

I measured 23" from the back of the flex disc to the center of the support bearing bolt hole, using the short N52 6 speed (GS6-17). 22 3/4' probably would have been better as you can see in this pic. You can also see some of the poor paint issues.
