What could be the problem with my 2005 Jag Xtype now?

Asked by Nov 15, 2013 at 02:23 AM about the 2005 Jaguar X-TYPE 3.0L

Question type: Maintenance & Repair

More problems with this car that I can tally!!  Now, if I go over 3200-3300 RPM the transmission seemingly fails to engage and the check engine light comes on and blinks.  I must let off the gas - dropping the RPMs so I can reengage and drive. Engine light stays on permanently.  Oddly, I can go 70mph as long as the RPM's stay under 3200-3300.  What gives????? Jag tells me (after they had it for 5 weeks, -- yes 5 weeks) that I need a new tranny.  Also JAG's main computer cannot communicate with my car.  The handheld can.....not the main one.  This is a new issue. I have replaced the engine, the cat converters, gear box, etc etc etc.  I think the tranny is the last remaining major component. Tell me its not the tranny please......could it be the tranmission control module???

Since the CEL is on, there is a problem. It could be trans specific. Hard to say if I don't know the 4 digit code. Instead of taking back to the dealership have a local independent shop diagnose it for you for a second opinion.

My husband fixed the same problem on my 2005 x type by replacing 2 O rings on the intake manifold. And then replacing the vacuum line to brake booster.

It cost my husband maybe $12.00 to fix everything and took him 30 minutes to complete. We haven't had any issues since. Love my Jag.
