Hi, my 1990 Eunos Roadster 1.6 is difficult slotting into 2nd gear and is quite notchy. Can this be fixed easily e.g. gearbox oil change?

Thanks

Might be worth checking your upper and lower gear boots, and check the oil level in the turret as this can make a massive difference.

Parts are sold as a kit, linky here Kit includes upper boot, lower boot, and the plastic bearing. Easy 30 mins job to replace, even for a numpty like me (probably 15 mins for a competent person!)

I hope that helps mate

I believe it can to an extent - have a little search and you'll find the recommended oils etc.

I think it's safe to say it's a fairly common complaint - it usually frees up once everything's warmed up a bit anyway

Great thanks for the info guys. I might go for one of those kits and change the gearbox oil as it's not too expensive.

It does improve as the engine warms up by the way! However, it's still notchier than the other MX-5's I've driven before.

As the car hasn't been used much over the past few years, could daily driving also improve the gearchange?

Daily driving in a '5 is always a good idea anyway!

haha, no danger of not driving it every day as it's my only car so it's a great excuse to drive it as much as possible

Been looking for some MTL gearbox oil but could not find it. Is this stuff ok:

Seems a bit expensive mate, I got 3 litres of this one for mine: Mobil Gearbox Oil (2 for the gearbox, and a spare for the 100ml you need for the turret). Depends if you want synthetic, I reckon the mineral oil is good enough (I am clearly no expert though!) and at a third of the price it seems a bargain

Thanks a better price, cheers! By the way, can I just change the turret oil for the main difference to the gearchange?

If your turret boots are torn or perished then it's unlikely that there is any turret oil in there anyway.

I used Redline oil in my Mk1 gearbox when I changed it and it did make a difference to the gearchange. You don't change the greabox oil as often as you do the engine so I figured it was wise to put some thing decent in there. If you email Oilman at Opie oils with your requirements he will give you the best solution, van't remember if he gives Nutz discount but there's no harm in asking I guess. He is helpful.

Oh just as an aside it might be a good idea to change the diff oil at the same time. It's probably not been done that recently either and it's the same oil.

Other than that it is characteristic of the Mk1 5 to have a notchy gearbox from cold. They are just notchy, no reason really. I used to think it quirky but that was just me.

Thanks all, Have now bought some suitable oil, the boot kit and a turkey baster

I've also downloaded a guide on how to do it all so hopefully I'll have something to do over Easter! Along with fixing my glovebox which fell off the day after I bought the car

Did I read somewhere on here that changing the plastic bearing to a brass one makes a big difference? I liked the idea of that but do not know the details of where to get the brass bearings from.

haha, was only joking! I like the Mk2's too

Glovebox is now fixed but I'm not going to risk putting more than a woollie hat in there in case it falls off again!

You will probably need a wooly hat and scarf to cope with the draughts coming through the shoddy seals on your shoddy roof

Er, of course being a, ahem, "manly" MK1 you will no doubt have the roof down all the time though

:-D quite true. I didn't realise it had a roof! I drive it rain or shine with the roof down!

I've been doing that since february. I wonder if there's connection between that and all the colds I've been getting.
