The Renault Trafic gearbox breaking is because it hates not being in reverse.
(this comes from a more than happy Renault Trafic driver.....also got a 'P' reg Laguna thats caused me no probs the last 12 years the missus has been driving it)
My old dearly loved old age pensioner Laguna estate ( I hate vans) was mechanically perfect when I scrapped it
The immobiliser was the culprit,Renault has a bad name for its electrics,I now know why
The repair would have been worth more than the vehicle so it had to go
