Hello there-! Here in North America we have companies such as AllData and Mitchell that collate the published information from GM, Ford, Chrysler, Toyota, Nissan, Honda, etc. They re-publish what the factory service manuals have printed. The Pxxxx code system has a couple of groups that narrow things down some.

The P0xxx are generic codes that are common and are designated by the Society of Automotive Engineers (SAE) and even though a P0440 would indicate a general Evap system failure, each manufacturer has their own diagnostic test sequencing both for the vehicle to find and set the code as well as for the technician to follow to test the vehicle to CONFIRM what the vehicle "thinks" is failing.

The P1xxx (vs the P0xxx) is available for each manufacturer to use. Within both the P0xxx and the P1xxx systems there are some commonalities. The Px7xx usually indicates a transmission code of some kind which coincides with your description of the problem (a transmission issue of some kind)

So, the diagnostic code system IS directing us in the correct direction. Now, is the code indicating the ROOT CAUSE of the problem, or, is the code a SYMPTOM of what is happening? This is where the technician needs to find out what VAUXHALL has to say about that particular code for that particular vehicle.

This is where you need to access an information system of some kind, read up what Vauxhall says for testing and then put 2+2 together. Usually you can access the information directly from the manufacturer if there isn't a company that collates the information in the UK.

BEWARE of companies that gather and publish "shotgun" "guesses" and indicate pattern failures and recommend replacing a particular part merely on pattern failures and if that doesn't work replace the next most common part......Very often several parts get "tossed" and if the problem isn't a part, hundreds of dollars get wasted.

Get the testing information for that code from the manufacturer. TEST the system. VERIFY the part failure before you replace anything. Effect a repair (be it a wiring connection, or a part, or a transmission pressure problem....whatever). Then VERIFY that the repair both solves the noticed symptom AND keeps the code from resetting.

Check, test, verify, repair, verify again.

not used a snappy scantool for a while now but there should be a troubleshooter section at the bottom of the menu choice on the main page..read codes/erase codes/live data etc etc.

this from memory only came available once plugged into a car with comms...from there you could look up the code with help tips.
