Trans Failure moves from intro

Sorry think i postede this in wrong area, Newbie's HUH!!!

Hi Guys, New on this site and looking for advice.
I have a 02' range rover L322 TD6 Auto. and have the following problem. The wife was driving yesterday on a dual carriageway and noticed what she described as ''clutch slip'' when she got to a round about and went to pull away ''no transmission!'' and " TRANS FAIL PROG" on message display.
now we had gone through some flooding on friday night, nothing too severe about 3' at most and she was at off road height and went through slowly.
Q. could this be connected? or just bad luck?

I have a copy of rave and see that there are several solinoids on the gearbox thinking maybe could be a problem. when you start there is a slight nudge forwards as though she is in D not park when you put into D same but will not move slight noise heard from box like thrust bearing type noise although only slight.

Any ideas?

ahhhh well ya know like to be polite lol

Not a lot of knowledge on here yet about L332s, but it is increasing steadily.
All I can say is I have regularly driven them through far deeper water, so I suspect it is coincidence, or perhaps the last straw if it was about to fail.
Some of the earlier ones did suffer from poor connections on the wiring looms that could throw up error messages and sometimes actual faults.
