Rebuilt 5 Speed
Just curious between sourcing a rebuilt 5-speed, extra parts (what shifter parts are hard to find and expensive?), and labor..... ballpark if Carl is doing labor, what is the price these days? It's way down the list but if my 4-speed eventually goes out, I may consider swap, I least I won't need the pedal box. My throw out bearing is making some noise and may need to open up trans. sooner than I want to. .
I found the 5 speed on ebay. It was rebuilt some time ago and the owner never did use it. It was $1200 plus shipping. BMW still has rebuilt ZF 4 speed units for $3k through BMW of Monterey or BMW Boston. Other dealers might want MSRP.
I have read a number of threads and there basically aren't enough parts available to do a proper rebuild on a 265 Getrag. There could be some here and there, but no guarantees that you'd be able to refurb a junkyard tranny to 'rebuilt' condition. SFDon does have used units that he has checked out and verified are good at a cost of about $1500. I saw quotes for getting your transmission rebuilt on posts several years old for $3000.
I could have hunted and posted all over looking for a used shifter platform to replace the one missing from my Gertrag, but since there are various ones for the later cars and only some fit the 265 and the E9, I chose to ask La Jolla to use their experience and source me the new parts that I needed. A couple of their prices were under what I could get from BMW of Monterey.
The speedo drive is the really hard part to find. You can take one from a 4 speed Getrag, not a ZF. Mechanical speedo drives were used up through '81 only. Some later Getrag trannys have the place for it, but blocked off with a freeze plug. Installing it is doable. Carl was able to find me the parts and a seal, for a cost of just over $300. Electronic speedo solutions are a bit more than that, and aren't stock. So I chose to get a stock one while the getting was good.
My 4 speed has a bad bearing, making some noise, but not horribly. Since I'm taking the car apart to fix the rust, now is the time to do the conversion. I was going to see about replacing the bearing on the input shaft, it's commonly available, but the problem bearing might be the smaller roller bearings, and they are NLA, so when I saw the rebuilt unit for sale, I jumped on it. I had a search running on ebay for it, so it was only posted a few hours when I bought it.
I still have some parts to source, but I think they are pretty easily available. There are several good posts about the conversion on this, and some other forums. The search function works well on this site.
