Peugeot Citroen Renault Gearbox Problem Fixed (limp mode)

AL4 DP0 Gearbox Repair part 2:    • AL4 DP0 Gearbox Fault Repair P1167 (s...  

In today's video I will take apart the hydraulic block of a Peugeot 807 fitted with AL4 gearbox.
Car starts and drive fine for couple of miles or sometimes less and all of a sudden gets into limp mode (stack in 3rd gear)
This problem is well known with Renault (DP0) and Peugeot, Citroen (AL4) gearbox.
Most of the time this fault come with P1167 which is a dual purpose code. In my case P1167 means low oil pressure inside the gearbox.
Low oil pressure can be caused by something blocking the oil flow around the gearbox. It might filters or pressure solenoids.
Looking around the internet and doing my own tests on this particular car I came to the conclusion that the problem is because of the pressure solenoids. So I decided to replace them and show you how it's done.
