My 97 XK8 error message of Transmission High Temperature comes on and immediately starts having shifting problems. It sometimes stalls and recently started having an Engine Not Efficient message. When this is happening it runs like it's running out of fuel. After a few moments or parking for a while it returns to normal and all lights go away.
In carpros response to the same issues on a 2000 Jaguar XJ8 • V8 FWD • 119,000 miles, instructions were given on testing. Would it be the same for this model or can you tell me how to test? My research has led me to the trans harness or the sensor.
Do you
have the same problem?

If you can do the basic things first like check trans fluid if you are able if it's dark brown or black then you have a more serious problem. It then needs to be scanned for codes so we know what direction to go as far as check it. If it is a 0700 code that is generalization code. The engine thing of not being efficient is probably due to the trans problem. Just from your description to me it sounds like seals are gone in one or more of the clutch paks as it acts up while warm not cold. It also sounds like the clutch in torque converter may not be releasing due to your stalling condition and I'm guessing on this when you come to a stop. If you can get it scanned get back with the code so we can help you better.

Thank you for the quick response. The trans fluid I no more than 6 months old with about 1K miles. It will only act up when the error message comes on and will immediately stop with the light going out. I'll check for codes and get back to you.

Tpic shows the causes for the 710 code which deals with the trans overheat issue. Code 1111 mean stuff is stored in memory of computer no action necessary. There is no code p1642 at least not in our lists so it 's probably not much. I cannot find any listing of the trans temp sensor unless it is part of neutral switch as there is a what looks like something connected but not marked in pic.
