Gear Box Locked UP?
#1

Vehicle shifts and runs great, get in the car some times and turn key with no start up? Nothing. Trac Control message and Gear box locked up message come up on instrument panel. I unscrew the J Gate screw and insert key and push it down and shift lever to neutral, remove key and then reinsert key, turn key on and the car starts right up and drives fine. Maybe low trans fluid? Ignition switch going bad? Gas cap needs to be replaced? Car has brand new battery installed. Need to check alternator voltage and confirm alternator out put is up to par?

I would check/replace the brake switch. You can do some testing. When you press the brake pedal, in a quiet environment, you should hear the switches clicking on the brake pedal. It is like a tinny metal blade noise. With the engine off, and ignition on, as you press the brake pedal, you should hear (and feel) the shifter solenoid operate on the driver side of the shift bezel (kind of light thump). If none of that is happening, the brake switch is suspect (VERY common problem). Sometimes, it is possible to bring a bit of life back into the switch by gently pressing/releasing the brake pedal a bunch of times. Or not, depending on how far gone the switches are. It is likely temperature dependent, too. In my experience, these switches do not fail outright, but become erratic instead. This makes it hard to do a simple meter tests as the switch is awkward (is it the right word here?) to remove/put back in place.
Best of luck, keep us posted.

Per your instructions, the brake switch is working fine, I can here the solenoid activate every time I press the brake pedal, pressed it 6 X's each time solenoid activated with audio noise. J Gate switches need a clean out or rotary selector switch needs to be replaced or shift cable adjustment next? I know how to perform all of the above. I'll pull the transmission fuses, clean and clean them first and see if engine starting issue continues? I'm well aware the the brake switch replacement fix is a PITA, two person job makes it easier and quicker.

No, the gear shift moves freely through all gears. Every so often I go too start the car even after driving it and it sits for just an hour and I get in the car turn the key and nothing, no start no noise. I remove the screw tab in the J Gate depress the button down, then shift to neutral, remove the key, insert the key, turn the key and the engines starts and vehicle drives, shifts great. Above action done according to manual and it does the trick, the J Gate switches or rotary J Gate switch may be going south or need cleaning, just removed and reinserted TCM fuse and ECM fuse, all is fine. Engine running now. Going out for drive check now.
Thanks,

It may be the linear safety switch mounted to the side of the shifter. You can open the housing and move this around to see if you can reproduce/solve the problem. These are known to fail. The not in park microswitch can also fail. It is also mounted on the shifter and when the shifter is in park, it hits the switch arm. If this switch is sticking, when you pull the shifter out of park, the tranny thinks its still in park. This switch is part of an assembly, to get it you buy the whole unit. A temp fix for this is to rattle shifter in and out of park a few times to free the switch, but it will eventually fail.

Disconnected the two right side connectors and sprayed with electric contact cleaner. To get to the left side connector and spray requires removing entire console, which is easy to remove the console, see youtube the Reverend guy he shows how really easy it is to do to remove the console. I chose too see what the result was after I performI had to go to Randy's, He's got the Taurus for $525.00, good buy. He's says they're tough to find in stock from his dealers, so good luck on that. China trade war is driving the market down, give 3 years to realize the consequence of Trumps decision on trade and NAFTA, I say if Trump gets re-elected it's because his iniatives/actions were correct. U.S. will re-elect Trump if his actions are correct. Trouble is electronic voting is all rigged and Trump will be out (even though he made America Great Again) because major corporations control the whole voting system and world economic's. We need to relocate to a better warmer climate, summers are too short here and we'er not getting any younger. March gun sales broke another record, while that Hogg imbecile will end up a bigger imbecile then he already is... He just doesn't know it yet.

I have the scope, rings, snap caps and bipod. Still waiting for the 10 round mag from POF. I looked at their website last night and when you look at the 10 round mag it state a 2 week delay before shipping. Today will be 5 weeks and was told it would come this week. Talk with you later. C

You won't regret getting the Taurus, get that .22 Mag ammo deal now that I sent you, they will run out of inventory probably by afternoon today. I am picking up your B-Day gift today and need to hang the painting so if you are feeling better today I can come over but you have to call me and tell me when? Did you take delivery on the scope and rings?

I need to know what electric tester to use in order to detect the "out bad switch" when it happens again? Just a circuit tester pinched into hot wire and other to ground or use a multimeter? It's just a switch so why wound't a circuit tester and pinch the hot wire and other meter cable to ground while tapping on the switch for continuity? I don't have to disconnect the negative battery cable off to test that, do I?

This another thing I want to mention: The "right rear switch lever" located down in the JGATE was only half the length of the switch above it, and I'm thinkin have the lever busted off? I looked everywhere for a flange of that metal too see if I can locate it (no deal), saw nothing. Is half that lever gone and I don't know it? I spray cleaned everything and pushed six times on that top right switch below the JGATE switch and it see to finally start clicking while I suddenly got an audible chime from the steering wheel coloum speaker after the 3rd press. I had the key while doing this.

Brake switch cannot really be "cleaned", but it can be repaired cheaply. Read down this thread for parts:

My seat/steer wheel memory won't function correctly. This may be a "Body Processor Module" issue that needs reprogramming or replaced and reprogrammed by Jaguar. Jaguar systems, many of them are proprietary, as you probably already know, this is going to cost me alot. I need the diff pinion seal and fluid changed anyways and they have to drop the whole lower rear end to get to the drain screw. $$$$
