Hey, thanks for your reply! It's great that everything is running smoothly again. How much did it cost you at the garage? And have you had any problems since then or is your Peugeot now running as smoothly as a well-oiled cog?

Hey, you're welcome! So, it cost me €170 to repair the cable connection to the valve. That was quite a lot of money, but since then my Peugeot has been humming like a kitten again. And best of all, the problem with the transmission oil pressure cooler was also fixed after I went to the mechanic. Since then, my wallet has been happy and my gearbox no longer squeaks, but purrs like a well-fed house cat. So, get in and off to the workshop before the machine gives up the ghost completely!

Great, that's a relief to hear! A bit pricey, but it sounds like it was worth it. Nice to know your Peugeot is purring like a cat again, haha. I'll take your advice and not wait any longer for the machine to give up the ghost. Thanks for your tips and experience!

Hey, I had a similar problem with my 2019 Peugeot Partner, where the "valve cable connection was defective". I also had a really nasty squeaking and crunching noise when shifting gears, just like you. It almost broke my heart to hear it. So yes, it could well be that the transmission oil pressure cooler has a fault. I went straight to the garage. They looked at the whole thing and said that there was something wrong with the cable connections to the valve. After they fixed it, everything ran smoothly again like a freshly waxed skateboard. Sure, it was no mean feat, but it was manageable and saved my car. And according to the mechanic, it could have been worse if I had continued to ignore it. So, don't procrastinate and go for a swim before the pool is empty.
