I have been behind the power curve on this. I will get firmer quotes next week. Here in Detroit everyone is starving and interested in anything they can do to keep their people busy.

I am concerned about the vibration. Might be worth try using a different trans (of same model) to see if it is the trans model or just that particular one.

I would be inquisitive and pull this one apart to check the reverse gear side lash. I have read that BMWs suffer from what I understand as a similar vibration and the fix is to re-shim the gear.

Even if we have to use a different trans, the bell housing design could be changed.

I have 2 getrags at my house and know where there is another one. I would still like to get the proto bell and throw it on a CMM to check out the measurements. never hurts to have a second set of eyes. the AMG of the era used this transmission and POS on this forum has an AMG SL with the same transmission so I dont think there is an inherent issue.

OK Lutz the bell is on its way to you. I hope you can figure out something I missed. I really really want to have the 5 speed again and I know others would like to have the option to.

The vibration issue is not new. I am not aware of anyone with a 4sp swap who does not have vibration. Some say they have more than others, but all seem to have it. I think it is primarily due to the lower flywheel mass from the 616 that is used. Did you have this 5spd behind a 616 or 617? What flywheel?

thanx Graminal, I will measure and model and see if something jumps out. I should be sending it back in about a month if the GF doesnt want too many honeydo's

Bajaman if you read through the entire thread...I know its getting very long at this point. You'll see that its in a 616, the vib is there based on RPM and has nothing to do with the speed of the car, clutch engaged or disengaged, in/out of gear.... and with only changing the tranny nothing else the vibration goes away. So its not like the 617 vib most complain about.

Thanks LutzTD, fingers crossed you can get it sorted. A simple 5 speed swap is in your hands.

What model/year BMW's use this transmission?
70's/80's BMW's are readily available in the "pick-N-pull" yards here in CA.
My 4 spd is starting to have problems at 289K....If I have to pull/replace anyway this might be another option.You just don't see a lot of low mileage used 4 spd tranny's out there.

The getrag 260 can be found in all kinds of bmw's. The 265 only came in a few years models (not 3 series). I started tearing one down in the pull a part last weekend just to see the guts... You really need a cordless drill to speed things up.

lutzTD · #**129** 02-27-2009, 08:09 AM

I can pull a 265 in about 20 minutes, all you need to do is loosen the engine cradle on the driver side, then remove the dirveshaft and shifter and the 4 bolts that hold it to the bell and it slides right out. They are usually in mid 70s 535, 733, 735 or mid 80's 535, 635, 733, 735's I believe they are also in some of the larger engined cars, but I dont see too many of them with manuals.

These are relatively easy to find,(they were the "yuppie's" car of choice here in the San Francisco area)especially as cars of this vintage are the ones most likely to be retired under California's increasingly difficult "smog check" inspections.The self service yards run different weekly specials.Right now it's on whole engines,but I have seen discounts on transmissions from time to time.I'll have to see about what they would run.
PNP also does large lot pricing.If you wanted 25,50,or even 100 or more to start making "kits" once this bellhousing thing is sorted out they might be the ones to talk to.The only drawback is you don't know if you are getting a "good" one.I have no knowledge about the cost or availability of repair parts(bearings,synchro's,etc)but I think there would be sufficient demand to justify production of a complete "kit".I have seen these type of "kits" to put either a T5 or T56 into vintage muscle cars such as camero or mustang.They are quite expensive due to the high costs of purchasing new transmissions(try about $2500-2700 for a T56 6 speed)If the repair parts are easy to source for these getrag units the kit pricing might be within reason due to the low costs of getting the "core" transmissions.

Thought,comments,suggestions???

Don't forget the custom flywheel in your kit. Unless these can be found cheap in some third world country, they will have to be custom cast as well.

the 240D flywheel would work, if that is indeed the source of the vibe then the 300D flywheel might be needed. If there was a group buy these could be fabbed but my guess is people will live with the vibe rather than pay $400 for a flywheel.

If a kit were made by me, I would give directions on what and where to buy but would most likely only offer the custom parts. reason being is that i have tried to do specials for car guys in the past. where there is a lot of excitement about the prospect, there is generally not a lot of follow through, and I would not want to get stuck holding all of the parts. Besides, I would have to mark things I purchased up for handling, cost of money, risk etc. the kit would be cheaper if you buy the stuff yourself.

This is a well known swap with Volvo 240s over here actually. There's a whole market for adapters and all sorts of parts you'll need to do this. Since I am searching for a reliable solution to get my W115 put together with both an 917 turbo engine and a 5 gear stick-shift in the future myself, I've been going through whatever concerning the matter in the forums lately.
With your vibration issue in mind, I just came across a bloke with the same problem. Right after the swap he had heavy vibration around 2500 rpm. He was about to give up until the starter was found to be the devil in the end. Probably resonance breaking it loose or something. I don't know. I just thought it was worth checking out, if you already haven't.

So what's the situation with this bell at the moment? I would definitely buy one, if it's turning out a well functioning piece. It will actually make my biggest dream come true. A 917.952 into the W115, in line with a proper 5 gear stick-shift.

A lot of guys over here pick their 265's from the W201-body. The 190E 3.0-24V for instance. Could it be possible to use the bell from those cars?

lutzTD · #**134** 03-11-2009, 02:46 PM

I have Graminal's bell. I did some measuring on it and found it to be pretty accurate. i am going to check one more thing and then send it back. I have been selling off all of my getrag 265's. 2 are on Ebay right now if anyone is interested. There is another thread with a plate set that uses the 5 speed from a W201 which looks promising so I am thinking that might be the easier path.

HansAA · #**135** 03-12-2009, 01:03 PM

Yeah? I've been searching with no success. Do you have the link? By the way, does anybody know the mecedescode for the getrag 265? Can it be the 717.450?
