Sounds like a Throttle position sensor adjustment or repair. You should be getting a trans failure light also.

What implications does a TPS out of adjustment have for the fuel injection?

no warning lights at all just harse gear changes

how do you adjust the throttle pos sensor, where is it located

 

[equiprx]

The only way I know how to adjust it on your engine is with a Jaguar PDU diagnostics computer. The TPS is located under the throttle body.

Could it be low on tranny fluid?

not low on atf just done change, and checked its level is ok

Okay, it was just a thought that struck me.... :wink:

It's possible that the clean out and the new fluid may make the harsher shifts. I personaly like the harsher shifts rather than the smooth ones. Smooth can be a sign of wear. Check a local independent transmission shop and do a line pressure test and maybe they can adjust your shift points to what you want.
