Q? Always had a bit of problem with getting reverse on my 4200 Coupe (86k on clock - I am third owner well looked after ) but last solved by gearbox oil change and re-pressurising the pump. car has been great ever since but suddenly, reverse has disappeared altogether - there are no signs/sounds of it even trying to engage. has anybody had similar experience or ideas?

Its really quite a simple one to diagnose really , it can be one of 6 things , either the reverse lever and its micro switch , the relay and fuse for it , the reverse gear actuator , or pump problems (leaking pressure,) or lastly the footbrake switch located at the top of the brake pedal , could be sticking but then again it would be the same for selecting 1st
Adding another it could possibly be the boot/bonnet opening switch/sensors , reverse cannot be selected if the boot is open/up its a safety thing and makes sense when you think about it

Slightly off topic but I find it very annoying you can't reverse with the drivers door open!

That is ridiculous, especially when in cities.

Seems the spring on my reverse switch is either broken or failling and I got caught recently with errors as a result. I now positively push the lever back quickly after selecting reverse. If you get a reverse error however just get out and push the car backwards manually about a foot and it clears it!

When I bought my car the PPI said:
* The reverse switch `detent` doesn’t seem to be working correctly, but it selects reverse perfectly well (the detent is a device that’s built into the switch to stop you knocking the reverse lever accidently whilst driving, and approx 90% of 4200’s we see here have the same issue!)
Basically the switch is quite fragile and is a concern whenever someone else drives my car
