Hi All I have just purchased a 1966 P5 3 litre in fantastic original condition, this one family owned car has never had any work done with only 9000 miles from new. This being my first P5 on driving it appears to me to be very late in changing into top gear ? it changes into 2nd at 15-18mph very nicely but it doesn't change into 3rd till at least 38mph -40mph, is this normal ? Admittingly I am not heavy on the throttle but even if I drive it hard on throttle it still doesn't come in till then, just seems too long to me ? It doesn't feel like it's slipping in any way just not ready to change up ! Wondering if anyone has any views on this as haven't done anything yet, the oil seems clean and smells ok not burnt etc I am going to check the oil levels as guided by the w/shop manual later today. Maybe someone has a similar model and can tell me what speed it should change at. Or wether it needs looking at ? oil change, filters ? as obviously been standing a long time, has only done 2000 miles in last 9 years. Really pleased with our purchase and will be looking to join a club soon. Regards to all Geoff

Hi Geoff...so you've got a MK3 with a BW35 and a 3.5 ratio final drive. Same gearing as a P5B V8 but your automatic has also got a rear pump fitted which means it will self start through the transmission over 60kph IIRC.
I also have a MK3 P5. In 'original' factory spec the trans generally likes to get into 3rd gear or direct drive ASAP and stay there! I'd say the issue with your transmission is most likely due to lack of use and sticking/gummed valves in the valve body, most likely the 2 -3 shift valve. I'd have the trans serviced and the valve body removed, disassembled and cleaned. This is a straight forward task with virtually only 3 adjustments required on your version of the BW35. Adjustments are: front band, rear band, and the cable adjustment that controls internal pressure (for the gearchanges) and kickdown.
PS. Would be keen to see some photos of such a low mileage car.

Hi All it changes into 2nd at 15-18mph very nicely but it doesn't change into 3rd till at least 38mph -40mph, is this normal ? You need to check the upshift speeds at low throttle, full throttle, and kickdown, and see what you get. Low throttle, 1-2, 8-11 mph, 2-3, 12-16 mph. Full throttle, 1-2, 23-30 mph, 2-3, 53-63 mph. Kickdown, 1-2, 35-43 mph, 2-3, 67-79 mph. Make sure the engine is in a good state of tune before you start, and bear in mind those speeds are for an engine in perfect condition. If your figures are at a medium throttle setting they're probably about right. The more you open the throttle the later the upshifts will occur.

Thanks Enigmas, sounds like you know your stuff ! yes that was my thinking as it has obviously been used very occasionally. That's how I imagined it to perform into top relatively quickly, my thinking was around 25mph ? It was owned from new till the gentleman passed away in 2009 then left to his daughter, who although has cared for it, doesn't appear to have any passion for it, thankfully she took the decision to sell so someone else can be the custodian. Obviously we want to retain it's originality but at the same time maintain it with preservation in mind. Do you know anyone we can entrust with an overhaul of the Auto box ? I can do most things but never had an auto box apart, altho I believe quite simple once you know what your doing, I could probably remove the box when I have time. I will try and load some pictures for you ( if I can work it out ? ) it is all original paint/ trim never welded and almost zero oil leaks anywhere hasn't got any car park dents very straight panel lines etc. Attachment Deleted

Hi Harvey Thanks for input, I will take another look at this over weekend, as only drove it once a few days ago, that's when it didn't feel right and fully expect some tinkering will be needed due to lack of use etc.
Cheer's Geoff

If it was me, I would change the transmission fluid and thn drive it a couple thousand miles before considering stripping it. Can you confirm the gearbox type by taking a picture and posting it.

Beautiful pristine car Geoff...looking forward to more pix (interior & engine) when you get around to it. I'm in OZ so can't refer you to an automatic specialist but Harvey can. I doubt you'd need to remove the trans (unless the seals are shot)...all the service adjustments/procedures I mentioned are easily carried out in situ by any competent specialist or owner with tech skills.

Thanks enigmas, yes I realised after I posted you were in oz ! Lol. One of our old cars is supposed to be in Perth museum ? 5000 mile Ford classic Capri ! I did think on it last night and wondered if your suggestions could be done in situ, so thanks again. I will endeavour to post more pics for you as requested of interior / engine bay etc everything is original even down to the carpets. Is there an email address I can send them to easier ? My computer skills are limited in resizing pics to upload ! I do also have an equally original P6 mk1 2000,19,000 mile Auto. Plus I have a 1961 P4 100,34,000 mile that I have owned since 1972, sadly this needs restoring but hope to do this in my approaching retirement ? All the best Geoff

Hi DJM Thanks for input, I did wonder if it would free up with use and oil change. I will try and get pics of transmission for you, as I do have a four post ramp but it’s got another vehicle under restoration on it , well very slow restoration like 20yrs lol. I will free the ramp in next week or so as I also want to have a good look underneath anyway. Cheers Geoff

Hi Enigmas, did the picture links work ? Took the car to a local show Sunday and the gearbox seemed to change better ? Think I've just read up on what the problem may have been ? apparently there is an intermediate gear hold lever, under the column, I wonder if this was engaged before and my switch fiddling may have switched it off ? will look in morning, the handbook states if engaged it will not engage direct drive until 60-65mph ! disengaged it engages direct drive 37-44mph which is what it was doing, I will investigate further.
It also appears from a very knowledgeable P5 coupe Mk3 owner that we have a Mk2, which on his pointing out the differences I must agree with him, and on finding the handbook tonight it also states Mk2.

In that case you have a DG transmission. Lovely car by the way.

All MK111s did have BW35 (or have I misread your post?), but not all '66 cars were MK111s, presumably they were using up 'old stock'. Having said that, I doubt many MK11s were actually sold in '66. Just had a look at James Taylor's book, states 443 MK11 saloons and 188 MK11 coupés (RHD UK market) were sold in 1966. Production of MK11 saloons (and presumably coupés, but not stated) ended December 1965.

Lovely looking car. That is a MK11. External distinguishing features are that the MK111 has a thicker chrome bodystrip, which terminates on the rear wing with 3 'chrome pips', with MK111 badging on the bootlid. The front grille badge was also altered and was bigger/more prominent, more akin to the P6 Rover 2000 style. It's probably be the same badge in a different housing, I haven't looked at one for a while.

The DG box can be set to give higher change up speeds and it also has a hold switch on the LHS to start of in 1st and give higher change up speeds. See handbook and WSM

I'm fairly sure your correct, that it is a Mk2, as you say it has Mk 2 chrome strips and hasn't got the three pips at the rear, I was also told the position of my time clock position, in the centre of the dash is Mk2, the door locks have the key barrel in button and not seperate below handle, washer bottle and power steering reservoir positions are different to Mk 3 ? and that Mk 3 has stainless trim around windows which mine doesn't have.
It was registered on 3rd May 1966 with Chassis number 77506179C if anyone has records ?
Not had chance to get underneath on my ramp ( blocked with another car ) as yet to visually check out the Gearbox type and mine certainly does have the Hold switch bottom left of steering column.
So at this time I will take it as a MK2,until someone tells me different.

Does James Taylor's book list the models by chassis number ?
It was first registered on 3rd May 1966 chassis number 77506179C

You definitely have a MK11. There were numerous other differences not previously mentioned, ie 2-tone MK111 saloons had the second colour on the roof, as per the coupés, chrome fuel filler caps, different seat styles, ie the same as the later P5B
Your chassis no. is a 1965 MK11 auto home market. They ran from 775-04294 to 775-06802
1966 model year MK11s commenced 775-06803 to 775-07099
MK111 (1966) chassis home market auto saloons commenced 800-00001 to 800-01558
The reference to stainless window trims is incorrect; it is the coupés, from start to finish that had stainless window surrounds.
MK11 autos ran a lower compression ratio engine than the manual, to better suit the DG transmission, MK111s, however, were able to run the same higher compression engine as the manuals.
