I would love to convert to a 6 speed...

I think the electrics/electronics would be the most challenging aspect of a conversion. You can buy an adaptor for the New Venture Gear transfer box (which is unique to the Range Rover) but I can’t help thinking that, overall, the cost of the conversion would easily exceed a replacement GM 5L40-E unit. Still be a very interesting project though.

....You may be lucky and just have an MV3 solenoid/reverse gear valve issue, so when you call around and one of them says it might be the MV3 - they might be the outfit to use, but the MV3 solenoids are usually very reliable - it does happen just that it's not common.

I think you’re referring to the ZF 5HP24 transmission here, but the GM box does also have a reverse lockout valve.



From the list of symptoms, though, I suspect courtec’s transmission has mechanical issues with the running gear and not just hydraulic/electronic ones, which unfortunately will necessitate a rebuild.

Sorry to start this up again.

Garage have called today and told me the car now goes into all gears apart from reverse after it’s gearbox service. Gearbox hasn’t been reconditioned yet however he is saying he thinks my reverse has gone so will need the recondition. is this true? i don’t know what to think now
