MF 5470 transmission fault

[W F Bourne Ltd]

Hi there.
Don't know if anyone can help, but 5470 dyna 4 sometimes won't engage reverse. Reverse light on dash doesn't illuminate, and number 1 by the shifter flashes twice slowly, then 3 times slowly, then 4/5 times quickly (difficult to count at speed).
Any ideas folks?
Thanks for any assistance.

That will be t1.23 for the boc switch .
Replace that first and if it still persists it could be a faulty f/r lever

Thanks for that. Please excuse my ignorance, but what and where is the "boc" switch?
Thanks again.

Bottom of Clutch switch... the switch that presses when the clutch is all the way down. Basically the clutch pedal isn't really a pedal connected to anything at all but activates a bunch of switches and potentiometers. I believe it uses the top of clutch and bottom of clutch switches to self calibrate the rest of the travel in the pedal. Ours has had its moments, but I think the only thing you can really do to help with these electronic systems is to keep the cab clean as dirt and dust can interfere with these switches.

Ok thanks for that, I'll try that first.
Cheers.
