2007 Harley-Davidson Flhtc Transmission and drivetrain Problems

“As I was slowing down in my driveway the engine, with out warning, made a loud metallic noise from the left side and locked up along with the rear wheel. If this would have happened at a greater speed, or in traffic, the consequences could have been dire. I removed the primary cover and immediately notice a large piece of steel had gotten jammed between the clutch sprocket and primary drive chain. This large piece of steel had broken off a pressed steel cage that enclosed a set of diaphragm springs from the crankshaft compensator assembly. …”

“I have a 2007 harley davidson electra glide. There is an excessive amount of noise and vibration that comes from the transmission in 5th and 6th gear. I put in heavy 75-90 gear oil and it got a little quieter. Now it seems hd has put in an isolated drive system in there 08 touring models as standard equipment. You can purchase the unit for $305.00 plus labor to put on the 07 touring models. Harley davidson knew they had a problem with the 07 transmission, fixed it on the 08 but want the consumer of an 07 to pay for the part and there mistake.”

“2007 hd,Flhtc experiencing transmission whine in 5th gear very loud ,and clanking noise at all times from 5th gear and sixth gear. Hd customer service was no help nor dealer although many other new owners experiencing exact conditions. Dealer and factory say its normal. Others have no symptoms. No failure or accidents yet. Very loud noise from a transmissions is not normal. Harley davidson has a problem and it needs to fixed asap. I ride 15000 miles a year and do not -trust this new motorcycle to perform its mission of touring. …”

“The contact owns a 2007 Harley-Davidson Flhtc. While riding 75-80 MPH, an abnormal noise emitted from the transmission. The dealer diagnosed that the transmission needed to be replaced. The motorcycle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 60,000. Updated 04/06/17 lj”

“Motor runs hot; found by using 89 grade, runs cooler and better. Also dealer uploaded new ignition program - harley issued a fix. Getting it done under warrenty. Gearbox noise: harley uses motor oil 20-50. Change it to full synthetic gear oil 85-120 (or something near). This quietens gear whine and makes it shift better. As a mechanical professor and on my 16th harley; never use 20-50 motor oil in any gearbox! Thats wrong in so many levels.”
