My experiences literally are identical with Poik. I've been running it for years, and I don't know when this happened. The Pennzoil Syncromesh has a 100C viscosity of only 9. Replace the parts from inside the car, then cap the hole with a plastic or metal plug and some body sealer. Should have saved my money.
This means that the ability to write new posts and access various member features will go away. There are 3 seals to replace - input, output, and selector shaft seal. This indeed fixed the rattle issue once and for all, but has more recently been lamented in many online communities as causing a bigger problem than it solves, as many customers that received this fix reported third and fourth gears grinding from time to time while shifting. All of the tranny saga is documented in the Bentley. I have three complete G265 as spares.
My E90 was purchased brand new and has the noise as do many other E90's. I actually gave the dealer a open credit card number and told them to order all the tools. Some would describe the sound like a bag of marbles, gear chatter, or similar metal rattling. Hiya Robert, the 'rattle' in my case is from the throwout bearing, I presume, because it does it at idle and clutch out. It sounds like straight cut gears in a dump truck.
The rattle at neutral in idle is often attributed to bad layshaft bearings. . There are three separate shift fork shafts, which hold three shift forks to activate the synchronizer rings for the two gearsets on each of the three gear shafts. With the E28, there were only 2 basic engines with very, very minor yearly differences during its 7 year production run. Locks for the most part are not terribly difficult.
I've been perusing the manual now for a few days and have a few comments when compared to the E28's manual. I've had problems and problems. If so, that's a pretty discomforting thought. The following was posted very recently. Having turned many a wrench during my E28's 250K miles of my ownership over 300K miles on the car and still running strong, but looking a bit ragged , the Bentley manual has been a godsend. I have a question regarding the parts list. I just purchased a 1990 E34 535i 5-speed a couple of weeks ago and got the Bentley manual for it.
We fixed the leak by going with a Viton output shaft seal, that we use in all of our Ultimate transmissions. I seem to remember hearing that the 265 is a better tranny, but I don't have any first hand experience. I am currently nursing such a patient. All that said, we do occasionally receive inquiries like yours - about working on Getrags for other car models. It can handle inputs of over 230 s 170. I can't remember if it was all the trannys the special bearings were supposed to be in or just the G265 which supposedly have unobtainum super expensive ones. The problem here was it would get extremely hard to get into first gear and other gears.
I did not have that and it was a bitch, I braced the trans against the tool box so I could push as hard as I needed. Noise is minimal and it would shift great if I could only find the freakin shifting rod bushing which is shot. I heard one that is very rattly and grindy though, still works fine. I have eliminated the diff as a probable cause, and now I suspect the half-shafts they have big play. This is the trans used behind the S5x family and is popular for swappers.
There where 2 service bulletins, well several but we are only concerned with the 2 main ones. They are not to be confused with a conventional rebuild. The first bulletin is for 'Hard Shifting'. Not loud enough to annoy anyone but definitely there if you know what to listen for. Carbon and molybdenum are extremely durable friction surfaces that remain stable even under extreme heat. The clutch release bearing is operated by a concentric slave cylinder that surrounds the input shaft in the clutch housing.
