I have been driving my car for a few weeks after it was off road for several years. It seems rather sluggish. I know from previous experience the carbs often need tuning and balancing, can anyone suggest a suitable specialist? I am in Devon between Exeter and Okehampton. Also I have noticed the gearbox is reluctant to change down to 2nd on anything other than kick down. What should I do to investigate this? I would love to drive a well sorted P5B to notice any other problems with mine as I have forgotten how slow/brisk the car should be!! Any offers - we offer B & B in a Georgian Manor House in Devon. I would be pleased to give a night's free stay for some help! www.devonbedandbreakfast.co.uk

With any gearbox problem first make sure the fluid level is correct, and the linkage is working as it should. Next is the kickdown cable which could be where your problem lies but you will need to be more specific about when the problem occurs. Are you saying that decellerating it fails to change down from top at all, or you're accellerating and don't get the performance because it doesn't change down then. If the kickdown inner cable gets frayed it can temporarily jam in the outer cable causing excess pressure relative to the throttle opening. If you have limited knowledge better to get someone who knows the boxes to road test it for you. If it is sticking in top it will give you the sluggish performance you are suffering from as well. You should also check the fluid condition (colour and smell) and make sure the selector pattern on the plate by the gearlever is the correct one for the type of box fitted. Incorrect selector plates are often fitted and this means that when driven the gearbox is not doing what you think (and it should) be doing.

Hi paugoo, I would take off the gearbox sump,(after draining the oil)then check the filter for blockages,generally have a look to see if anything looks out of place,check the kickdown cable by placing an old mirror under the g/box then checking the cable up top in the linkage area to make sure that when you move the throttle it then coinsides with movement on the cam in the box,this you can see by looking down at the mirror.Adjust if required and re fit. Worked for me,although i replaced the cable as well. Good luck and your place looks great,may one day visit you. Big Kev.

Thanks for the suggestions. I don't think I can do what you suggest, but will pass on all the information to my local man..
The car changes up and down quite smoothly and kick down works fine, it's just when I slow down to say 20-25mph, it still seems to be in top instead of second. When I come to a stand still it goes into first as it should.
The selector has not been tampered with as far as I know. I have had the car 22 years and I knew the first owner, as I sold him his replacement (Saab) car. The Rover has only done 59K but has been out of action for a few years, so I suspect the fluid is dirty and old, and probably any filters are also poor.
Any P5B owner on the forum would be very welcome for B & B at a heavily discounted rate!!

It seems to be OK its quite normal for it stop in top, it should change down though when you accelerate, it may be the engine needs tuning but before doing any adjustments to the box it should be checked for correct operaton per the manual if fluid condition is OK and at correct level take withe ngine running

It's difficult to be sure without driving the car, but it sounds as though it's working as it should. If when you are slowing down and get to 20-25mph it will remain in top as the throttle is closed, if you accelerate away again it should then select second.

Hi paugoo,
Mine has had the box overhauled and still loves to change up to top at about 15 mph if not under load! Will also come down pretty much to the speeds you're saying in top befoer that characteristic clonk into first!

Will also come down pretty much to the speeds you're saying in top befoer that characteristic clonk into first! Andy Changing into top at 15mph on a light throttle is just within the recommended range (just) but a bit in the low side suggesting low pressures, but the clonk into first is a symptom of high pressure so it may be the clonk is in the prop or diff. If you have both the problems (upshifts too early and a clonk on the downshift to first) caused by the box, not the driveline, I would think there may be an internal fault.

When the speed drops off it's not a problem that it's still in top, but when I then accelerate it does not drop down to second, so I either have to kick down which is a bit extravagant or move the lever to 2nd. This can't be right, especially when faced with a hill! Paul.

Without a test drive I'd think it was kickdown cable ajustment, which could just be the bush in the bracket missing if you have the later set up, if that's all OK try upping the pressures a touch.

I will print this lot, and take it to my garage man. Thanks for all the help. I would like to drive another example though, so please visit sometime www.devonbedandbreakfast.co.uk I'll have to add some Rover pics to the gallery page!

Yes its always a good idea to drive another, assuming its good any way, to compare

I bought ours in August '85. Nice looking place, just needs a gathering of old Rovers outside. Next time we're coming down we'll give you a call as your offer sounds very tempting & will make a change from the caravan.

The workshop manual describes in detail how to test the gearbox operation, when it should change gear up and down, how to identify certain symptoms and how to remedy faults.

Agreed but it has to be gained or found with someone reliable, so the W/s manual is always a good start for the uninitiated unless there is a wish to fall prey to the many rip-off merchants out there

Unfortunately I do not have the mechanical expertise to attempt these jobs myself, nor do I have a workshop manual. Paul

Renewal of the fuel filter is an easy job that can be easily overlooked. It can often be blocked with dust yet still allow starting.

The fuel filter job is one I can manage, I suppose I can get them from JR Wadhams? Paul

Go mad and purchase two of them, one can be used as the fuel filter and the other can be used to replace the crankcase breather at the back of the engine.

Yes I do fly down into Devon, was down there a couple of Sundays ago. I was close to you at the beginning of June on my way down to the Tavistock area for the Steam Fair, in my 3 litre Coupe.

It's a V8 that mine would like to see. It hasn't seen another of it's own breed for over a quarter of a century! Paul
