Another Tranny Problem

[pylon500]

Hi Guys, Been a long time away (Moving and building a new house ), and have slowly been building up some odd problems with my '92.
The most recent (and important?) is after first start up, when selecting D or R, I get a sudden judder, sometimes a minute wheelspin, and the engine stalls.
If I hold a bit of gas (1500~2000) and select a gear, after about the 4th stall, the juddering goes away and the car drives normally.
I'm assuming I have a problem with the TC locking up at start?
Plenty of fluid in the box and still reasonably red.
All subsequent starts, selections and changes while driving are OK.

Next fault is with my climate control.....
Every now and then while driving along, I would hear a beep and see that the climate control had selected the outside temperature momentarily
Sometimes it would alternate between the setting and OAT repeatedly which would get very annoying.
Then the climate control setting would start beeping down to the lowest setting and stay there, if I tried to reset it, it would just beep down again
The other day when it started beeping, I looked at it to find it was now going to the highest setting! Fortunately my heater core is disconnected as it has a leak

Oh yeah, that's another problem
I've read the posts on replacing the core, and I'm not looking forward to that one!!

An interesting note on the climate control, about a year ago I noticed that when I turn the lights on, the P at the end of TEMP stays bright, about a month ago the M would stay bright as well.
In fact I think last week the E was also bright.

I was having a problem with the headlight fuse blowing, but that turned out to be a loose wire in my trailer plug.

I'm also hearing some exhaust gas noise under the 480k klm engine, but cannot find a leak around the manifolds and suspect a burnt valve?

Most of this may not be too important as I have another engine and tranny (160k klm) to swap, but reading those posts, I now see I've got a JDM front cut, and will have to do all the speedo mods

So, any ideas on the tranny lock up problem, are any of the other problems likely to be related?
