Getreg 245 M20/M10

[draper68]

So I'm in the middle of an M20 swap on my '69 2002 and the mechanic doing the install just called me and told me that he dropped the euro e21 323i getreg 245 I'd sourced on a work trip to Germany years ago and bent the gear selector rod. I'm a bit panicked now because not only are these things almost 5x more expensive now than what I paid in Europe 10 years ago, but they're almost impossible to find! But then I had a thought, and I'm hoping someone who knows more about this kind of thing can help. I still have the Getreg 245 that's bolted up to my M10. I know the bell housings are different for the M10/M20 versions of this transmission, but are the internals, most importantly the gear selector rod the same? Can I cannibalize the M10 Getreg to save the M20? Thanks in advance!

Yes.

blush.  anything for the M20'02 crew.

How's your's coming? I haven't seen any updates in a while. M20'02 SoCal meet-up late summer/early fall?

You didn't say if it is an over drive box or a Dog Leg Close ratio box.  If it is an overdrive box then everything inside the box is interchangeable with your M10 245/5

However...

 

changing the shift rods on a G245 is not a trivial task.

@PreyupyGood point of clarification. It's an overdrive box. I couldn't even find a dog leg box in three different German scrap yards 10 years ago! 

 

@TobyBWell, my mechanic broke it so he gets to fix it on his dime! I wouldn't dream of trying to crack open a 45 year old transmission with my tools and skill set. Thanks for the heads up though.

You might be able to find just the m20 bellhousing to swap onto your good box. There was a member on here selling a couple few years back.

Where are you located? Before you scrap a perfectly good 245/5 just to get a good shift rod I probably have a few out of damaged boxes ( holding can be good sometime). I’m out of the shop until Monday but could look then. 

[draper68]

I’m in the Bay Area. I have no desire to butcher vintage transmissions, but my car is on the lift at the shop and I’ve gotta make some moves. If you’ve got a shift rod, I’d be very interested!

[Preyupy]

I’ll try to get to the shop on Sunday and see if I can find a good shift rod. 

[draper68]

@Preyupy Any luck with the shift rod? I'm still interested

I finally found a good one.  It has obviously taken a hit from a guibo that let go at some point.  It is straight and the nick in the shaft does not get into the shaft seal
