Greetings

My 1983 2.8 litre automatic Patrol has trouble getting into gear when cold.

I put it in reverse and off it goes, never an issue.

I try to put it in Drive and sometimes it doesn't engage or does engage but stays in first. If stuck in first I simply manually shift to 2nd and it seems to sort itself out. If it does engage drive I put it into first or second and sooner or later it engages and off we go.

Is this an electrical fault?

Regards

Alan
