Have a search for 4L30E repair procedures and this guide pops up http://scottj.info/files/isuzu/4l30e.pdf. Lots of words and pictures - the procedure, on page 79, for adjusting the brake piston looks plausible enough.

Cheers Andy. I'm puzzled that it should require resetting though. My gut pessimists feeling is that it is more likely the clutches. :y

The brake bands are presumably a wearing part, so tweaking isn't unreasonable  :-\

I suspect you may be better just throwing on another AR35. Sorry.

Thanks guys, remind me where the clutches are, and how to adjust the brake band. :y
When the sump is removed there is a dome held on with 3 or 4 bolts. Remove it and there is a threaded screw with a lock nut, release it then tighten the screw to 5nm torque, back off five turns and then tighten the lock nut, this sets the brake band. Replace the dome then it`s a gearbox re-fill

I'm going to tackle this shortly. Which sump is it under? I don't recall a dome under the filter in the rear sump. :-\ :-\ :-\

If anyone knows the answer to this I would be grateful, as I had both sumps off a few months ago, and do not want to take them both off again, if I can get away with one, and I would like to get on with it tomorrow. :y
