Ranger Auto Gearbox Failing!

[PeteB]

My high mileage, GreenMech tow tug is starting to fail with gearbox issues (the diff is bloody noisy too). Symptoms are that pretty well continuously, almost like a heart beat, the gearbox drops a gear and changes back up instantly. Sometimes only noticeable by looking at the RPM, others with a pronounced judder through the truck. Ford have had it on the ramp and plugged it in but no codes are recorded and they tell me that to take it out and send it off could cost a few thousand. Any gearbox gurus in the house?

Had similar problem on mates Ranger, used to tow mini digger, conclusion was worn out box, too expensive to fix only showed up when towing, traded in

Had gearbox problems with my 2013 Wildtrack. Transmission control module diagnosed as the issue. Unfortunately it's buried inside the gearbox. I had a new box including torque converter fitted 2yrs ago. I think it cost about £5800 all in by local Ford dealer. That developed similar symptoms last June and had replacement fitted under warranty. So far no further issues. Mine isn't towing heavy loads day in day out aand has only just passed 90k. If you can manage without it for a couple of weeks I think a reputable gearbox specialist would be able to resolve it. I spoke with a specialist prior to getting it done at Ford dealer they were confident they could sort it out but I would have get the gearbox to them and probably 2-3 weeks to check source parts and repair. I couldn't manage without it that long.
