Well, I've bought a 420 SDi, was wondering if it is possible to change out the gearlever unit to get something with a bit shorter throw & nicer change? I've changed them before on rearwheel drive escort which was pretty straight forward, I was wondering if the one from something like the MG ZS has a nicer shift, or if it will be the box itself - ie not adjustable.

The box is the same, a PG1 unit. I've got a ZR, and the change on that is okay, fairly tight and firm, but not very quick. It is very hard to miss gears though. It is a big improvement over my bubble 200, which was very slack (but was a lot older though). A ZS gearchange mechanism might be better or worse than a ZR, probably better though as it is a better drivers car, and almost certainly quite an improvement over your 400.

Modify the selector to make a quick shift. Easy enough if you have a hacksaw and a welder then you can make one easily.

Thanks for the quick replies.

I almost bought a welder at Netto the other day for £20... might have to, lol, though I don't know if it will actually weld steel... might only be for plastic or something. :p

I'd rather have a spare in case I get it wrong, it's easier to back to the original then. Will keep an eye out for someone breaking.

I'm sure my dad will know how to modify one (not to sound like a little kid or anything, he's 60 and has 45 years experience as a mechanic).

All you need to do is chop 20-25mm out of the bit above the "ball" part and weld that into the bit below the ball part. This means that the lever has a smaller "throw" between gears.

Yeah, not sure if that's my problem tbh. Looked today, I think I need some new bushes for the linkage, it's all a bit loose.

Yes that is a really common problem too.

Often it isn't the rubber bushes that are at fault, it is the metal pins in the linkage that wear in their holes. There are various methods to sort the problem out. The same gearbox is used in a lot of the rovers, so the problem is really common.
