Ok so I recently bought an 1999 XJ8 automatic and am wondering what the 4,3,2 gears are for ? I know in other cars they are used for when you are going uphill, he told me they are used for when you are going over 100mph , but I'm preatty sure he's wrong ! Please any ideas would be nice

 

 

Welcome to the forum Eddie602,

Good to have you with us at Jaguar forums.

The Jaguar J Gate allows the driver to hold gears - if you select 2, 3 or 4 the transmission operates automatically but will not engage higher gears than the one selected.

Follow this link XJ XJ8 / XJR ( X308 ) - Jaguar Forums - Jaguar Enthusiasts Forum to the X308 forum for help, advice and information. The 'HOW TO' thread at the top is a good place to start for information on regular issues.

Please remember to add vehicle details to your Signature to help others to give relevant advice. Go to the User CP button on the left of the top menu bar, then Settings & Options under Your Control Panel. Select Edit Signature and enter the details.

Ok thanks I dont think I will be using it as much but just wanted to know .

 

I have a message on the dash that says restricted performance! This happens from time to time especially when I drive long distances (1 hour or more of highway driving) it goes away by itself, if I am at a red light the engine is not smooth at all, but I put in neutral and it's helps it a little . Also I can't go past 70mph without it jumping !! Plz help!

Eddie,

You should post technical questions about your model in the X308 (XJ XJ8 / XJR ( X308 ) - Jaguar Forums - Jaguar Enthusiasts Forum) forum but I'll get you started on this one.

Restricted performance can sometimes simply be caused by poor fuel quality but there's many other possible causes. To start troubleshooting, you should have the DTC's (Diagnostic Trouble Codes) read. I understand places like Pep Boys in the US will do this free of charge.

Post the codes (the actual codes - not any descriptions they may tell you of what they mean) in X308 forum for help with interpreting them.

Ok I will thanks
