Aaargh - PRNDS!

well decide I had better look at this myself so ~I know where everything is and what to do ; jacked up ,front wheel off , wooden blocks under for safety , found the connector on a bracket , couldn't undo the connector

finally undid the bracket the connector is mounted on and then found one half of the connector is held on by a clip so held clip open and levered open with flat bladed screwdriver ...easy when you know how
both sides of the connector nice and clean
had a hunt on my neighbours workbench and found a WD 40 product described as non silicon lubricant suitable for using on electrical equipment including circuit boards ; gave a good spray on both sides and then used the airline jet to remove excess then reassembled

tested transmission and removed fault code had a test run .......and no fault code

so far , so good

if someone had told me that the forward half was held on by a clip would have done it in half the time !
