Hi, for couple a weeks my autobox (AR35) acted strange and is slow to engage 1st gear after hard break but only for first mile or two - after that it seems to worm up and work perfectly

Any ideas?

I checked the oil level and topped up (0.4l was missing) still the same behavior

Am I looking at a new gearbox soon?  :-/

Service the box? Possibly sticking solenoid....? Maybe  :-/

Could try the above, they can be revived with a fluid and filter service.

But any slipping is usually bad news.

A r35's change hands on here for about £100 or so, ish. So not the end of the world if it's failed.

Although that depends where you are in the world...?

Thanks mate,

here they go for around 200e, 5years ago when my original AR25 died it was 400e.

Should I go for (rare?) 5 speed auto. Is it a straight change just autobox and computer, all wires same? How reliable are 5speed autoboxes (only latest Omegas had them?)

5 speed box is entirely different and was only available on some 2.5TD Omegas sold in europe. I doubt it can be retrofitted without a lot of pain.

Thanks for info, I'll go for straight swap 4speed if autobox fails. Oil and filter was changed 2 years ago but car was not driven much for better part of one year
