JCB 1400B Tranny inoperative when hot

[Dan73]

I have a JCB 1400B, the tranny works fine when cold but after approximately 10-15 minutes the tranny will quickly decrease torque to the rear differential, and does not propell the backhoe in forward or reverse. THere is a warning light and buzzer on the dash, I do not have manuals and am unsure of what this light and buzzer represents. All other hydraulic systems work fine. Is there a common problem with this model?
Where do I start.
Thanks,
Dan

Dan Im not sure about the JCB but it sounds like your tranmission filter is stopped up. I had a 580 Case and a 655 Ford and a Terex craper do that one 3 different jobs. THe light is a transmission filter or temp light. Change these filters and the fluids in the transmissiona and it should be fine. Take care Taylor Lambert
