Automatic gearbox issues

[kevjimbryant]

My 1970 2+2 has two automatic gearbox issues.
First, when moving from park to drive it doesn't do so smoothly, it jolts and the car wants to leap forward.
Second, I'm sure I'm not getting third gear.
Any thoughts as to the possible causes and remedies?
Thanks kev

Kev, it may seem patronising, but isn’t meant to be. Have you followed the manual as that will talk through lots of these issues?
I’ve no experience of auto boxes, however if you can detail what you’ve been able to check and compare to the destructions in the manual it will help those much better experienced in the black art of auto boxes.

Good luck, Geoff

The manual would be best to check first, It's quite a comprehensive section, but look at Service instructions.
Having bought my S1 with one in, I did have much work to do, from memory the first thing I did was adjust the mechanism so ''Park'' and ''L'' actually matched the detents, then following the manual did all the adjustments and checks from the outside of the box, like rear band and governor etc, all accessed through the grommets in the tunnel. Next I think was the kickdown cable, what a horror that thing was.
