    A New Auto Transmission Option for P6B and P5B

    "I'm sure you need to adjust your kick down (throttle position sensor), it really does make a big difference to the behaviour....." Is Peter's box electronic, then? I thought he had a mechanical control box? HP22/24, not HP22/24E?

    Differential Output Shafts - Time to give up?

    I'm on record as being a fan of the Rover Diff, stating that the diff itself is pretty bomb proof and that all it needs is stronger output shaft material. That's drawn in part from knowing that the better material approach works for the long input shaft in the extension case. And from never...

    RPMs versus MPH Mystery

    Problem solved. Beautiful car. Envious. Were the problem not to have been solved, there is one other (unlikely) possibility that you guys missed. There were TWO final drive ratios available for the 2000 and 2000TC. Standard was 3.54:1 as everyone knows. But optional was 4.1:1. Developed for...

    LDV Pilot gearbox (R380) or LT77 17A

    Rover themselves trialled overdrive on the P6. Their first attempt was to simply borrow a Triumph 200 O/D box. But their second attempt was more interesting. Instead of mounting the overdrive on the back of the box, they mounted it on the front of the diff, behind the prop shaft. In that...

    A New Auto Transmission Option for P6B and P5B

    Peter is a fan of modern multi gear auto transmissions. So am I. But not behind a Rover V8 that retains most of it's broad power band. There isn't really a "sweet spot" in the engine's power delivery, so it's silly to try and keep the engine spinning at a particular rpm. I reckon four gears...

    A New Auto Transmission Option for P6B and P5B

    Any gearbox with an overdrive top gear - less than 1:1 - is going to leave you very high geared............. But there's a double win available. It isn't only the diff and box that determines overall gearing - the rolling diameter of the tyres is in there too. So, fit tyres that are undersize...

    Auto gearbox V8 p6

    The guy who wrote the W/M and the Owners Instruction Booklet may well have been several guys and may well have been selected for writing skills............... All the engineers knew already and never used the books............. But seriously....... Rover treated the box as a bought in lump. The...

    You'll find me on the Australian P5 and P6 FB Group, Mike.........

    1966? I dont think so!!

    As regards the interior details. A careful look at the photos of the 2000S in the James Taylor book shows that everything was ready by 1965. You can speculate endlessly as to why these weren't incorporated in production P6B. My personal best guess is around the timing of P6B launch. The final...

    1966? I dont think so!!

    Remember also, MikeMelb, that when the batch of Buicks arrived from the US there were no specific P6B's to put them in. The second series of P7's were repurposed for trialling Buicks and no doubt they finished up in other mules too. I too saw the Fishwick engine in the metal. By then it was...

    A New Auto Transmission Option for P6B and P5B

    Apparently there is a fairly narrow window where the boxes have lock-up but are still on cable/rod control.....

    A New Auto Transmission Option for P6B and P5B

    There is news from Down Under in Australia...... A second automatic gearbox has been identified that fits and works readily in P6B (and P5B). In the UK and Europe, the upgrade to a ZF HP22/HP24, sourced from a Range Rover, is an established retro fit. That gives an additional overdrive 4th gear...

    rear suspension on a Pb6

    The oil lubed tubes rely on bronze bushes for the slidey bits. So oil is essential. On the grease tube these are replaced by a yeloow mesh of a PTFE loaded nylon. They need only the most minimal amount of grease.

    Sleipnir's very early original engine

    Mmm. Rust in the bores... Why did you sideline the engine in the first place? Given rusty bores, the correct action is to pressure test the block to see if you have a loose/slipped liner... If not, then start by trying the existing rings in the bores to see what their ring gaps are... A...

    Rover P6 4.6 V8 Road/Race car.

    Alex, I rckon the uprated roll bar will be a revelation. My guess is that you'll need to go up to 600lb at the back to keep the same handling balance. Or put up with a tiny bit more understeer. Cobraboy, I'm intrigued to see how you did the neg camber. I've worked up a couple of ways in my...
