JCB 530/70 transmission light

[kevindb880]

We have a 1998 JCB530/70, it has I believe 7000hrs on the clock, recently when it’s been used a while and everything is warm when you shuttle from forwards to reverse the transmission light blinks and the warning buzzer buzzes for a split second.
Everything transmission wise works fine but it seems to be doing it more as time goes on!
Worn transmission perhaps?

I had one do just the same.

Any idea why?

No sorry. Chopped it in for a new machine as didn’t want to spend anything on it.

Have you changed the oil and filter? And the gauze one at the bottom

 

[kevindb880]

Not due to be changed so no!

I changed the sensor on mine and that cured it but it could be a host of things

Any idea why?

Faulty sensor
Low oil blocked suction filter (should add if blocked then theres other problems going on too)
Worn pump and clutch pack seal etc.

Start with the top 2 and cross fingers?
