hello everybody I have a recently purchased mk11c which is very reluctant to kick down. after studying the w m and some posts on here they all refer to a rod from the accelerator cross shaft to the governor ,, my car has a very! loose cable instead ,also the governor lever is quite loose; for the first quarter of its travel and then has spring resistance from there on and a firm click at the end. the cable fitted has no provision for adjustment I am at loss to know where governor travel should commence and finish! there is no mention of setting up this linkage in the w m can anybody shed some light --should have a cable at all? help!

Phil will be along in a minute to confirm, but I thought MkIIC and on were BW boxes. The DG box on mine definitely has rod links. Perhaps you could post a photo or two?

Yes the all P5s to Mk2c inclusive had the BW DG box which had a fully rod linkage EXCEPT the kickdown/gear hold which is both this cable and a column switch operated electric solenoid. on top of the box. This has a lot of slack but the point at which it holds gears longer at change up can be changed by adjusting the solenoid position on top of the box. The handbook and workshop manual gives the adjustment if needed. Both publications are essential if you need to maintain these cars properly. What problems have you with the gear change? Note that 2nd speed start is normal and is desirable unless kickdown is used or the column switch is dropped and then it will start in first

hello thanks for your replies, my issues are that box shifts into top at about 35mph will not kickdown above this speed,and will not engage or hold intermediate speed hold above this speed. I was in the process of adjusting the solenoid when i discovered the very slack length of bowden cable that connects the crossarm lever to the governor when observed full depression of the throttle pedal results in about three quarters of the travel on the governor lever, I have the proper rover wkshop manual which details the solenoid body adjustment ,but make no mention of the kickdown mechanism at all!! any references to the kickdown linkage only refers to rods , never any cables, Ishould add the cable as found has a clenched nipple and a clevis at each end so not made by an amateur. the cable is so slack it lays on top of the gearbox at rest definately a dg box by the way
i tried to upload pics but could not make the images small enough technophobe!!!
many thanks for your replies paul

The kickdown relies entirely on the Intermediate Hold solenoid position and the normally slack cable. The change speeds are all determined by this cable and the adjustable position of the solenoid.
I am taking our Mk2c out tomorrow evening and compare the change up speeds with yours - but yours seem on the low side. This implies the solenoid is turned too much clockwise (B) direction. I have mine set more anti-clock in the (A) direction
1. Will it start in 1st with the Intermediate Hold switch down? 2. Will it start in 1st with hold switch up on almost full throttle? 3. Is the fluid level correct when HOT in Drive?

I thought the solenoid only controls the intermediate hold and that the kickdown switch under the accelerator is independend from that solenoid and takes you to the maximum speed in the two lower gears.
I recently had the solenoid adjusted - I didn't use kick-down since then. I will check the kick-down-speed the next drive.
I too have experienced far too early shifting up. A loose ball joint in the linkage was the problem. An easy cure, just clicked it back together.

thanks for all your input . Ihave adjusted the solenoid as per wm and your advice, i managed a very brief test drive (dodging rain) and it seems much improved. my concern over the cable was on fully depressing the throttle the operating arm on the governor does not open to its fullest extent, this may be as intended but thats what im not sure about? Hopefully i can give it a proper run out soon (IF it ever stops raining) many thanks for taking the time to help out with your replies. regards Paul

A loose ball joint in the linkage was the problem. An easy cure, just clicked it back together. The kickdown switch is not actually a switch merely a stop for the pedal to allow full pull on the solenoid Bowden cable. The P5B has a similar arrangement under the pedal. The spring loaded plunger in it can seize but a firm push down on the pedal and some lube may release it.

I was able to try the kick-down this morning. My car will hold second close to 100 km/h when pressed. Intermediate hold will keep it in second till 70 km/h.
