Let us know please.

yes all other gears show up properly but i think the car does not know it is in drive when you select d so it jerks when selected initallly then it drives fine 2-3 change sometimes is sticky but auto fluid also checked and that to is fine one other thing if u select d it will only show on dash display the last gear selected ie n or r or 4 or 3 or 2 then after 30-40 secs it shows blank please help

This sounds familiar.. Is this the Jatco autobox? What mileage have you done? Are you due up for a change of gearbox transmission fluid?

I seem to remember reading a thread similar to this (although perhaps in another forum???) and the outcome was that the car had done almost 100000 miles and not had the transmission fluid changed at 60000, the recommended interval. I recall that the chap had it done at a cost of £100 or so and it transformed the car.

Interestingly the Jaguar X-Type which uses the same JATCO box has variable fluid change intervals.

If the X-Type has covered mostly motorway (extra urban) miles the fluid need only be changed at 90,000 miles or 6 years.

However if the X-Type has covered mostly town and city (urban) miles then the fluid should be changed at 60,000 miles or 4 years.

I noticed the same symptom today on mine. I had just turned down a steep hill when I noticed the indicator display had blanked. I pulled in for a closer look, but after a couple of selector shifts all seemed well again.

The car is almost due a 4-year service so the fluid change will be carried out then, probably for the first time.

Well it's worth looking into. Check the service records to see if it's been done.
A pal who knows auto gearboxes very well tells me that worn out fluid/low fluid level can cause intermittent problems of many types. For what it's worth, if this were my car I would find a local automatic transmission specialist who has experience with Jatco boxes and book in for a fluid change, but when discussing the price (should be around £100-110 but no more than 150 tops) check that he will be putting the fluid in at the correct temperature.

Auto Gearbox Problems

Dont want to worry you but when i purchased my 75 auto 15 mths ago every thing seemed to be okay with it. I took it out on test run and all was okay. I had a warranty of 6 mths left from the previos chap and had it transferred to me. After 3 weeks i started getting a clunking noise when i tried overtaking anyone not just with the kickdown but if i changed it down manually. Took it to rover agents they took it for a test drive and said the second gear changing piston had cracked and needed a new gearbox at £4500 + new gearbox ecu. The warranty i had only covered me for £2000. I contacted the warranty people and they gave me 2 contacts who would change the piston and rebuild the gearbox, one was £2200 the other £1800. I sent it to the second choice which was Bristol Auto Tranmissions, because they were the nearest to me in Cardiff. They picked the car up and lent me a courtesey car inplace of it. The car was off the road for a month, not all the fault of B.A.T but also the warranty company. The fault of the gearbox is a manufacturing fault with all JATCO auto boxes up to 2001/2 when they modified the box.If you have this problem do not tell the warranty company that that it is a manfactures fault as they are not covered on extended warranties. Since having the gearbox done all seems to be ok and i have not had any problem since. I did not need a new ecu, all you do to clear the memory is disconnect the battery for 30 seconds and when you reconnect it, it will readapt to the way you drive.
Hope this is useful info to all.
Jess.

Thanks for your comments Jess. The JATCO box is perhaps the most unfortunate weak point as this is entirely out of Rover's hands and owners of Galaxys etc will also have similar problems. The quote you were given by the dealer is absolutely outrageous though. What makes it worse is that they would not be doing the work as they will not have the tools or trained people for the job - it's more than likely they would trailer it to the garage where you took your car to anyway, hence making a tidy couple of grand markup for the trouble. A dealer local to me tried the same trick, thankfully I have friends in the trade who pointed me in the right direction. It goes to show that for some jobs using a specialist can save you a lot of money.

I'm not so sure in this case however that the problem is mechanical - it sounds like an electrical fault - but getting the oil changed is always a good idea, and if it is running low then it is essential that the cause is identified and repaired. Driveshaft seals can leak on occasion, although not common.

Always go for the cheap option first..less than £60 to change the oil in our local gearbox place in Norwich.

Good luck...keep us posted on progress?

A couple of things rattling about in the back of my head from snippets I have read

The Autobox seems to only have an average life of 100,000 miles
read that in several places (not here though) when choosing my 75

The ECU could need a software update or just a simple reload

The adaptive memory may have got screwed up disconnect the battery overnight and see what happen

The last two plus the oil change are comparatively cheap options to explore before open heart surgery

What is the engine's R.P.M at 105 km/h[64 mph].?If at 2100 R.P.M.,that is 5th gear.....if it is at 2800 R.P.M. then it is in 4th gear..

Jatco Auto Box

I am not aware that the Jatco box is a weak point and after a keen interest and looking at the club site for a long time now have yet to see of many problems with the Jatco Box. Jaguar, Land Rover,Mazda and Nissan to name a few all use the Jatco Box. They claim to be the largest manufacturer of auto boxes. My m/i/law's H reg Mazda has never given trouble and all her mileage is town. As for £4500......... well. Ashcroft Transmissions will fit a fully recon box for £820 ish.
It is recommended to change the fluid at 60,000 miles and one member said the box acted like new with smooth changes etc after he had it changed. By the way there is no filter to change in the Jatco box. The change is a simple drain and refill exercise (with plenty of time to drain) and the box will not take the stated capacity as a refill as some remains in the box. The car must be brought up to operating temp after initial refill before checking level again and topping up. Whatever anyone says only fill with Texaco N402 fluid (Rover part No. VYK00040/Land Rover LNR 402) which from a Rover dealer is £20.70 per 5 litres + VAT. My Rover dealer quoted £70 something for a change but auto trans. places will do it for less. So not very expensive. The Jatco model No is JF403E. I am expecting the Haynes manual, when it arrives, to detail a DIY change of fluid wheras a year ago it was unknown territory with all kinds of warnings !
I suppose like anything there is always someone who is unlucky whether it's manual boxes, clutches or HGF but the Jatco box on the whole is a very reliable unit

I have to disagree in part crofts - the specialist who repaired mine has also done a lot of JATCO boxes in the past few years - at first nearly all were from dealers who didn't have the skills or tools for the job, now it's older examples with worried owners. Personally I put it down to the dealers not doing their work properly, and this applies to franchises other than MGR too.

As JATCO did not originally supply replacement parts (I think this is still the case too) they had an account with a supplier in the Netherlands where they would buy new units, ship them over and strip them for the bits required. With the Exchange rate it was far cheaper to do it this way instead of locating them from the UK. Now they buy in the parts from America where a company has set up to manufacture them and they stated to me that the quality is far better then the OEM kit. Right now my box has done 40k since the rebuild and it's been better than when I had it 5 years ago. The oil change will be next month - sooner than required but I prefer to do it early rather than late.

There is also a club guide to changing the oil for those who have the equipment and feel competent to do it. No need to wait for the Haynes manual.

I wouldn't put to much faith in the Haynes manual, I don't trust the accuracy of the content more than about 75%

Sods law says the mule they use for the photos will be a manual 1.8 club saloon!

And why oh why are all the photos they take so badly lit, tiny and haven't they heard of colour yet seeing as they have virtually cornered the market I give them 3 out of 10 for most of their manuals

Just been thumbing through my Haynes manual for my Picasso trying to find out how to get a look at the aircon condenser not a mention of it anywhere!

All I wanted to do is verify where the leak is that the garage tells me I have :-(

Haynes are great for cars that you can repair using a knife and fork anything more sophisticated and they do tend to fall down.

I don't know about the service schedule MGR had but my 75 had done about 55,000 km and the auto was working ok. I think the auto service was supposed to be at 100,000km but I decided to do the auto trans oil early.When I changed the trans oil, the transmissions changes were way smoother and made me think what the condition of the trans would have been if I had waited until 100,000 km. I think anyone who wants to keep the car / tranny in good condition,Id be doing the oil at about every 50,000km.

In our parts the Jatco box seems bullet proof....and seems to last way longer than clutches and flywheels on manuals. They've been lucky to get 30 thou kms and manual diesels are lucky to get around the block! There are plenty of Jatcos past 100 thou kms/160 thou miles on other makes and nearing that on 75s. ...my theory is they don't like the cold. But I agree the oil service interval should be halved at least, just like MGR'S suicidal 24 thou klm engine oil recommendation....7 to 10 thou is more like it.....and I still maintain clean oil solves VIS problems.......cold treacle is not good on micro motors.
