I got a 1998 jcb 532 telehandler and been having issues with the transmission. It will occasionally not shift when you change direction and now it will flash the transmission low pressure light when shifting into gear or even at idle when hot. I checked the main pressure at the test port and it’s around 120-125 psi at 1000rpm. I am running ford type F atf cause that was equivalent to what the book said. Just wondering with that pressure if trying different oil in it or with that pressure it’s pump and possibly clutch’s leaking?
