"Transmission fail safe mode"

[kiethton]

So to round out a st weekend the above appeared as I parked up last night, had the transmission rebuilt approx 5 months/1500 miles ago, thankfully still under warranty from that (1yr).

What's the likely cause?

Battery is 6 months old, was replaced as part of a long running FSR issue now resolved.

I've called the garage and they seem to be honouring the warranty this far as is was only 6 months/2k miles ago it was reconditioned, got to get it recovered to them on a flatbed though, they have said not to drive it

So after the motorbike was stolen on Friday, this happened on Saturday and today my "good" road bike gives up on me...I'm now transport less

6ft, 18 stone bloke on a women's road bike for 30 miles a day seems to be the only option now haha!

Slipping torque converter was the initial reason, when they opened it up they found a worn bearing so I got it refurbished

c.£1,800 from memory, paid the extra for a full rebuild to get the guarantee

Popped on when the GF was moving back and forth (2 times in each direction) trying to baypark

Took it to the garage, new gearbox switch

£225 later and it happens again the next day...

Now back in on Saturday and they thankfully still have the old one. His time when it happened I over from R to D, lever resting in D, go to pull away up a slight incline and it hasn't engaged the gear. Metallic "Clunk" from the box, error message comes on as before and I'm stuck in 3rd.

Turning it off and on again fixes it...for now...
