Sorry, we're not going to get any more detailed than auto and manual. I get where you're coming from, but we don't want to confuse people into not making a choice. We're going to keep the transmission choice simple, you can choose the one that is most appropriate, and explain more in your vehicle description.
Just edited my cars, and the Subaru went in fine, but when I went to the Ford Fiesta, it wasn't showing entries for Body, Engine or Transmission (and they were greyed out). Going to update a couple of times, and first the engine model came up (which was already entered, as the system knew it was Diesel), and then eventually I got all the options up and could update the car with the transmission.
I edit the vehicle description via [edit car] every couple of days (because I store the progress of the current tank in the description at each of the dial marks).
However I don't think that the problem occurred when editing the description, since it seemed to occur between two edits. The activity that I can recall at the time was viewing the new chart, looking at my profile & vehicle page and reading the forum. I don't think there was anything different to what I normally do every day.
Oh yeah, I also added a tank a couple of days ago (I've edited the description twice since then), and also used the Cost Analysis feature. But this is all stuff I do frequently & normally there is no problem.
Out of interest do you use any sort of replication? I.e., can car details get put into any sort of backend cache before getting written to the DB, or are passed from one system to another? I've personally found that steps like that can sometimes introduce really weird errors if the replicated data becomes inconsistent.
PS fuel type, engine layout & transmission were the things which disappeared. It seemed to go when I clicked 'edit car' (i.e., I could see that it was already wrong when I was editing the description).
