99 Accord, 160,000, automatic, 4cyl vtec, properly maintained.
Recently the CEL came on following an episode of the engine running poorly. It painted EGR code P0401 which is being dealt with, and,
P1739: “third clutch pressure switch circuit fault.”
I investigated briefly in my Haynes and found that P1739 is one of the codes that will not trip the CEL.
I have not had any major issues with this transaxle. The fluid is at its proper level, Honda Z1 brand, and in good shape. I have it changed every 20,000 miles. Sometimes if I am driving along in 2nd gear, right around the upper speed limit before it would shift to third (20-25 mph), the car will jerk just a little but it is driveable. Could this be related?
Should I let this slide until something happens or should I get thee to a transmission tech. asap? What would you do? Could the thing go into limp mode one day without warning?
