T180 2008 Gearbox Issues

[namead]

Hello all

My 2008 T180 decided to give me a scare this morning. Cruising on the M1 near Sheffield in the 50 limit, graunching noise and speed drops - hit the clutch, looking for warning lights - none. Go into 4th, power is on and increasing. Into 5th - power and drive, into 6th - graunching and nothing

Seemed to run OK in 5th to get me to destination, but in neutral, clutch up - bag of nails. 1st a bit notchy and noisy, same for 2nd

With the clutch pushed down - no noises (OK, so there's no engine input to state the obvious)

Reverse is there too, just 6th has disappeared and in neutral, lots of noises

Is it selector failure? synchro failed? cogs disintegrating?

It was a sudden loss of power - not gradual. one minute it was there, next, nothing

Its got 132,000 miles (and a new engine)

sounds like 6th has gone. Think that there is a post somewhere on TOC (could be Auris/Avensis/RAV) that had similar. Certainly not common (not any consolation if yours has gone though).
