Hi all, new to forum and this is my very first post. I have a 96 XJ6, it dies when placed in drive. I have let it idle for as long as 20 minutes, selector in drive and it dies, as if key turned to off. It displayed some codes, P1775, PO727 & P304, 304 is an easy fix, more than likely a defective coil, plug wire or plug. I am concerned with the other two. I have cleaned the EGR valve to help P1775, no change. Based on what I have read on this site, the situation is bleak. Is there anyone out there who experienced these fault codes and resolved each one? Any ideas, thoughts, and help will be appreciated, thanks.

As a '96, you're in the wrong forum. Try posting this in the XJ40 forum, you'll get a better response

 

Moved to X 300 forum.

 

Firstly, you are NEW, so welcome to the real world of motoring.

I have ONLY read about this issue,and have NO experience with it.

There are many posts regarding the torque convertor "lock up" section NOT freeing itself to allow slippage at idle, thus allowing the engine to continue running. The XJ40 cars had many issues with this, and the transmission in the X300 is basically the same unit.

Lack of trans fluid changes allows a lot of black goo to build up in the system, and that will certainly block any ports that are small enough. The fix is generally a trans dissmantle and cleanup when it is as bad as yours, coz basically you cant drive it to clean it out with numerous doses of fresh trans fluid.

The torque convertor itself actually seizing mechanically, is also well documented, and maybe this is the case with yours.

No easy/simple fix as far as I know.
