Hello
Thanks for using justanswer.com. My name is ***** ***** I will be assisting you with your question. The site will automatically prompt you for a phone call request but that may not be needed as we can continue here in the text forum.
I am sorry you are having this issue and I will do my best to assist you.
Your problem is a transmission issue specifically the torque converter. What happens is the engine will surge slightly during a steady cruise. The repair for this was to clear the Transmission Control Module Adaptions and perform a special software update. If the fault returned then the converter was to be replaced. Of course the first step would be to have the transmission fluid level and condition checked. Since there is no dipstick this is not easily checked. The fluid could be slightly low from leaking cooler pipes or from the fluid sump pan/connector sleeve. Let me know. Thanks.
I will check the fluid level and condition.
If its ok i will have to have the module fixed. I presume only Jaguar dealer can clear and update the module right? An ordinary repair shop may not be qualified or have the necessary tool right?
Thanks
Correct. I can tell you that some dealers may not want to do the software update as if it fails the TCM would need to be replaced and that is very costly.
The 2003 uses the ZF 6 speed and not the Ford 5 speed. Ford also uses ZFs in their newer vehicles but the tools that communicate with these are different. You can contact local European shops in your area to see if they have the Jaguar IDS/VCM setup.
Ok great. Sounds like a plan.
Not really but the 2003 was the first year and it did have some issues. One was the converter. They are mostly effected by low fluid from leaks and if that is not corrected they do fail.
I will check the oul level in the tranny tonight. How do we do that on a 2003 s type? Do you have a picture of tje location of the level plug and the fill plug? Thanks
I will send you over the procedure. It says its for a XJ but it is the same for the 2003 S type with the 6 speed. This must be done on a level surface of lift and temperature is crucial which is why we use the diagnostic tool to actually monitor the internal fluid temp.
You are very welcome.
There is also another small annoying problem with my Jag: when i close the driver window, when it reach the top, the window automatically comes down all the way, i raise it again and it comes down a second time, somerimes a 3rd time then finally the window stay close, have you ever heard of this problem before?
Could be a bad motor or a restriction in the track/regulator causing resistance. The motor senses this and will not auto up.
The garage will change my torque converter either Friday or Monday. I ordered one from Rockauto.. they will change the oil the filter and put a new pan gasket.
