Hi Goz,
Thanks - yes, I'm looking at putting another battery in just to see what happens. Will let you know for sure! Hah, a heat sensitive car battery. Must have had a crack or loose joint inside. Lucky it didn't go BANG! I've seen the result of a truck battery that did that. Ugly, stinky mess! Lucky no one was nearby at the time.
Also, rang PJ yesterday. He sends his best regards. What a thoroughly decent and helpful chap. A Jag man. We had quite a chat. Sounds like he's doing well. Gave me 4 options, all very sensible, will send pricing. He thinks it might be a solenoid problem. Anyway, for now I'm going to drive in in Manual mode, as so far, that's been fine.
But it's all a bit weird. Manual gear changes must use different routines inside the
TCM, or why don't they mess up sometimes too? Maybe they will... ;-(
