Hello,
Read some other post with similar problems, but not the same deal..

This problem started this winter, during a snow storm and driving the Jimmy,
auto switched to 4 hi, did not see it change just noticed the light when I
stopped at a light. Clicked 2 hi and it stayed.

This past weekend with heavy rains in NY I was driving on parkway and it did
it 2x's again. It stayed in 2 hi for the rest of my drive home.

The recent work done was for an oil leaks and have had several trips over
the past 8 months as new leaks appear.

If memory serves me correctly this is what has been done.
Replaced hoses 2 different types I believe remote and radiator.
Replaced the remote holder.

The leaks have gotten better.
I know he has "washed down" the engine to check it do not know what
chemicals he has used but it was foul smell for the ride home.

I still have a small drip but when I bring in it 2 weeks for the LOF I'll
have him check the leaks again.

Is there anything I can get him to start to check, the problem is obvious..
it is so intermittent.

Thanks,
Dave-
