I had some trouble this weekend shifting into second gear under load and at speed to climb the hill at MSRC. The clutch was fully depressed but I could not force the car to go in second gear from third unless the car itself slowed down below 20 mph. Is this a known problem with the TR3650 or some sort of safety lockout? I don't think it's the clutch because it engages well and I don't have the problem anywhere else. Blipping the throttle / increasing RPMs didn't help either - it would grind if I forced it but I could tell it didn't want to go in gear before it ground.
