Thread: D2 V8 Goes forward in D but won't engage reverse. Auto box.

Hi all,

I've just been away and got back on Saturday night, reversed the truck up the driveway and parked it up. On Monday morning I needed to move it and it wouldn't engage reverse gear, it will drive forward no problems. So I checked the ATF level and that's all good. I went for a quick drive down the street and back and forward motion seems normal but I still don't have reverse. Absolutely nothing happens when you shift into reverse. So I put the Nanocom on, there are no faults showing (except for the oxy sensors again), the M&S lights are not flashing. The shift indicator lights on the console and dash light up correctly with no flashing. So I thought maybe a a dirty plug for the xyz switch or maybe the switch itself.

I took the xyz switch off today and opened it up thinking it might be dirty wiper contacts but mine seems different to the ones I've read about online. I've included pictures of the xyz switch as well, it seemed quite clean to me. I did think with the river crossings that it might have had water inside, but there wasn't. I;ve since sprayed it with contact cleaner/lube.

It also has had new Maxlife atf auto fluid change (4 times) and filter approx 5k km ago. Its been driving fine since then.

Does anyone have any ideas what may be the problem?

Thanks, James NZ

yes, in fact everything works as it should so driving forward works, it just won't engage reverse.
