(Hopefully) Final post to update the transmission saga: After dealing with BMW NA since Sept. 20th, and going back and forth with them over my request that they buy back the bike and replace it, which they declined to do -- I brought the rig home on Dec. 4th, and actually made it all the way home without another trans failure. Unfortunately it's either been raining hard or snowing ever since, so the rig hasn't been out again since bringing it home. I hope to rectify that this coming weekend since we're actually supposed to see that big bright ball in the sky for a few days.
There is a 3rd trans in the bike, supplied under warranty by BMW. However, getting to that point involved quite a bit of back and forth. I'm told that "tech experts" in Berlin attempted to duplicate the failures of the first two transmissions and they came to the conclusion that it was my fault -- ostensibly I was "riding the shift lever". As I told them, I've been riding motorcycles for 52 years, I've been a motorcycle safety Instructor for 34 years, and I'm currently the only Sidecar/Trike Chief Instructor Trainer in the U.S. And in that capacity I've ridden hundreds of makes and models. I think I know how to ride. And I did relate to BMW NA that I was insulted by their accusation.
The dealer showed me the torn apart 1st trans, and it was obvious that a pin on the shift dog had bent about 30 degrees and put a huge dent in the shift drum, which caused it to lock in place and wasn't allowing me to shift out of 4th gear. BMW NA tried to tell me that the pin had backed out, but it was pretty obvious that wasn't the case. It was still solidly in place, but was significantly bent. They were never willing to retract their statement that they think I caused the 2nd trans failure, and they did insist that the dealer "properly adjust" the newly installed (between the 1st and 2nd trans failures) heel-toe shifter to my foot, riding position, and riding gear before releasing the rig back to me.
However, here's the story on the 2nd trans failure from the dealer's perspective: Most BMW transmissions (when shipped as replacements for failed units) come to the dealership "dry". (No fluid) When the 2nd trans arrived at my dealer's place, it was full of fluid. The dealer assumed that this was the way things were supposed to be with the R18 trannys, because they'd never done one before. Immediately upon my first ride with that new trans installed (last August) there was an audible whistling noise coming from the area of the transmission, that even the dealer noted was present. After that trans failed in less than 28 miles, the thought was that when the transmissions are built they fill them with relatively inexpensive fluid, run them through all the gears to make sure everything works, then drain that fluid before shipping the trans out. The dealer believed that someone might have made a mistake and left that "test fluid" in there before shipping my 2nd trans, and since that "test fluid" was never meant to be used under load, that's what led to the 2nd transmission failing as there were metal fragments throughout the entire trans due to parts literally exploding inside the case. However, BMW NA denied the use of anything other than factory spec trans fluid when testing new transmissions at the factory, but did admit that the unit should have been shipped dry rather than full. (NOTE: When the 3rd trans finally arrived it was dry.)
After LOTS of back and forth with BMW NA and the dealer, and the dealer's area rep; BMW NA authorized a 3rd trans install, and threw in some nice financial incentives in an effort to make me happy with the fact that my brand new R18 spent the entire summer riding season in the shop. Hopefully everything will work as promised from this point on.
