SOURCE: I started to go and felt a vibration in the rear?

If this problem raised a trouble code light indicating a fault code in the gear box, it is most likely a defective solenoid in the transmission and will require a service tech to repair and diagnose. This problem is not repairable by most people without the proper tools and diagnostic scan readers.

1998 S-reg jaguar XK8 drives perfect until reverse is selected then goes in to reduced performance mode. using a fault code reader fault code P1646 and P0706 were read.

Seems likely it is just a transmission cable adjustment needed. Please see my whole note (not a musical whole note) above under Clarification...

I'd go to this site and read the info...

Xk8 Jaguar cooling fans do not come on at all. I have checked thermostat for engine. I have taken fans out and they work with a battery hookup. I can't sem to find a fan relay. Fan fuse is good. Car...

I had the same problem on my XK8 and I figured out that due to the age, this could be a failure of the thermostat. The thermostat is a valve that is closed when engine is cool and opened when it is warm. Quite often for being old is does not operate properly and the coling liquid is being blocked in one part of the circuit. The temperatuire sensor starts the high fan mode that keeps on all time.
A way to check on that is to see the behaviour of the cooling fans. If the high cooling mode of fan only appear after a few miles nd keep on going from this point it is very lickely a problem a thermostat that has to be replaced. Just have to purchase one in any internet reseller and get your mechanical shop to replace it.
