if it is a jatco 5 speed box it needs rebuilding or replacing. rubbish gearbox, but double check selector cable adjustment first.try using a fault code reader to check dtc codes in the tcm,[transmission control module] was the fluid clean that you drained out? or did it look dark instead of crimson and smell burnt? did you check the level with the fluid temp between 30c and 50c the correct procedure if not followed and you get it wrong can make a big difference to gearbox performance, but it sounds like the box is on its way out have.worked on these cars since day one.

P0456 is not a Jaguar code, you may be using an incompatible code reader, You can check the codes here http://www.bluejag.co.uk/decode.php

You need to reset with a ODBII reader, or have it done at a repair shop, its not normally expensive.

P0171 system too lean bank 1
P0174 system too lean bank 2
links to information on the codes

it means that the O2 sensors in your vehicle detected a lean condition in their respective banks. this could be caused by a dirty MAF (mass air flow) sensor or a vacuum leak downstream from the MAF sensor

sometimes you can clean the MAF with electronics cleaner or brake cleaner but be sure to take it off the vehicle first. be careful not to damage the MAF while spraying the cleaner, and allow it to dry completely before installing it on the vehicle.

It shows that your fault management system has been recently reset. It will not bring on the engine management light. For more info on fault codes goto

this is missing or incorrect data of engine rpm . you should try to erase the code , with a code reader and then see if it returns, and/or take it to the dealer to check. Hope this helps

these are lean codes. 171 is system too lean bank 1 and 174 is system too lean bank 2. what this relates to is you probably have a vacuum leak. look under for signs of obvious breaks in vacuum hoses. this is your most likely culprit. happy holidays

This code means that system to lean, bank 1.
some of the possible causes to make this code set are
1. intake or exhaust leak,
2. problem with the air system.
3. MAF (Mass Air Flow sensor)VAF sensor (Volume air flow sensor)
4. fuel pressure/pump
5. injector(s)
6. HO2S (Oxygen sensor)

I assume you have cleared all the fault codes (eg. P0150 - P0167) and the Jaguar generic code (eg: P1000)?

Often the problem is that you know you have fitted the part - but the car's computers don't know and so they have to be 'told'.

Clearing the DTC codes is relatively easy with a decent Code Reader (EOBD CAN) but the Jaguar Generic code is sometimes not so easy as there is a road test sequence that often has to be performed before the 'Engine Light' (MIT) goes out permenantly.

A local MOT Garage often has a Code Reader gadjet and charges around a modest £30 to sort it.
