daimler 250 v8 1967 recomissioning

Three things:

1) What's the tickover speed? If it's too high this will happen
2) Have you checked the transmission fluid level - this should be done hot with the engine running, having first cycled through all the gears. Any cold level mark you have on the dipstick is likely to be quite innaccurate.
3) What colour is the ATF? It should be deep red, and have no burnt smell. If it's discoloured, I'd recommend a fluid change.

Oh, and a fourth thing - if you get stuck, ask Harvey on here, he's forgotten more than most people will ever know about auto gearboxes, a true guru.

Cheers

when I put the auto box into either drive D1 or Reverse with my foot on the break there quiet a big jolt in the car. The car does not surge forward but it is a noticible jolt. Having never driven an automatic I am unsure if this is normal or there is something lurking in the drive train I should take a look at.

Check for any excess play in the drivetrain, (prop u/j's and diff) as well as engine and gearbox mountings. Make sure the idle speed isn't too high, aim for 750rpm maximum, and then if you've eliminated those then the kickdown cable may need adjusting.

...What colour is the ATF? It should be deep red.....

Donax and similar "old school" fluids - recommended for these according to the 1961-1971 edition of Autodata - is only slightly coloured and then it's a very pale orange but won't be easily visible on the dipstick when it's clean. Last time I saw red ATF I was topping up a pair of Strombergs with it as it was the modern stuff that's quite unsuited to older auto transmissions (but fine for those carbs' dampers). Don't take the risk, this is one area of tribology where current spec definitely isn't best.

Dear Harvey

many thanks for the advise I will check out all the mounts as I have not checked these so far.

When I took it out fotr a little drive I throught I could hear a noise comming from the prop so I may take a closer look at the UJs as a matter of course. The Diff seems ok and showed very little play when I stripped it earlier this year.

I set Idle to about 700 at the moment. You will haev to excuse my ignorance on the kickback cable comming from landrover stock. but I will research and check that out to.

many thanks for all the advise I will get to it.

best regards

As long as the end fittings are the same and the LR kickdown cable physically spans the required length from the throttle linkage to the transmission, I don't see why it wouldn't be suitable. It may even be the same as the specified one for the car.

John, I think he means he's not familiar with kickdown cables in general, as proper Landies don't have them.

But then I think perhaps you knew that too, and are just being cussed....

[lhubbard]

you are right I never heard of one at all in the landy world..

well the four I built dont have them. I think I need educating to their usage..

Ah, all I read was:

the kickback cable coming from land rover stock.

So them oral there is that one ought to read the whole post or better yet, try not to do this when doing actual work on another device... (Can't be bothered quoting the post to see it as that's a proper faff on the phone screen), but if it's something along the lines of "dense" then guilty as charged.

The kickdown cable is a device that's found on cars with automatic transmissions, its function is to make a downchange when you floor the accelerator pedal, I assumed that the one fitted was from a different vehicle. Apologies for being distracted.

[lhubbard]

Ahhh that clears it up. I have not disconnected anything so I assume it been fitted. I have also not disconected anything. I will double check to make sure

It is possible to dislodge the outer cable from the adjuster while working in the same area, and that will cause the problem.
