My first car was a morris 1300 4 speed auto (quite advanced for 1970) (the auto that is) and it could be pushed started - well tow started anyway.

Did it have the dreaded hydrolastic suspension ???

It sure did

I could have sworn I heard someone lamenting over the uhf on a recent drive that the constant gear changing was becoming a p*ss off? Think it was a bloke named blknight???:p
am I mistaken?

Why is it then, that when I move the selector from Park to Drive or Reverse for that matter I get the dreaded clunk and feel as though I've been kicked up the backside if theres no direct connection from flywheel to turbine until certain revs are reached? Am I on the right wavelength here???

OK so can you tell me what are the plusses and minuses of my auto that seams to have 2500-300rpm stall converter? I have discovered the heaps of power and suck you into the seat launch.
Guessing it means I can't reverse down steep hils with engine braking?
I have rock crawlers in the transfer and find I can drive down in first at about 10kmh with the engine doing around 3000rpm.

What is your idle rpm ?

Not exactly sure on idle rpm, don't have a tacho. Are you suggesting its too high which would explain what I get when I select? May also explain why I go rocketing down steep hills even in low range 1st nessecitating standing on the brakes all the way. What should my V8 idle at?

Not sure exactly on your model - but I would have thought - at normal running temperature you should be at about 700 - 750 rpm.

If I am way out I am sure somebody would correct this.

Thinking about it, it could be even lower.

Good way to check - get it as low as you can before it starts to complain/cough/stutter.

For the later Classic RR it's 525 +/- 25
