I have a JCB 214 Series 3 backhoe with 1775 hrs. on it. I bought it last fall, did a full service, changed all filters and fluids, including the transmission. Replaced the oil and filter with factory JCB equipment. I put about 90 hrs. on the backhoe with no problem, then the transmission oil pressure light started to come on at an idle about 700 rpm. Changed the trans filter again and no difference.
The light goes out about 1100 - 1200 rpm and operates fine above that rpm range, but comes back on at an idle. When this started, I noticed the light coming on only in forward / reverse, but now the light comes on regardless of it being in neutral or forward / reverse. When pushing into dirt piles etc. the trans doesn't seem to be slipping, but at an idle it is very slow to change from forward to reverse.
The sump screen was clean when I changed the oil and I cut the filter that I had just changed apart and I thought that it looked pretty clean inside. No filings or shavings, but a little bit of metal dust stuck to the metal of the filter (thought that would be normal wear with all the gears running in the transmission).
The transmission oil that came out of the hoe was red, just like ATF. There must have been a little oil left in the torque converter because the oil has a red tinge to it even though the JCB oil is clear. I would have thought that if those two wouldn't combine I would have had problems earlier.
It sounds like JCB's are plagued with electrical problems. Could this be an electrical problem, or do I have a trans pump just going bad? Oh, the trans is a synchro shift. Any help would be appreciated, I've very frustrated that I'm having these issues with a 1700 hr. machine!
