I have a Raymond 425-c40tt that has no back tilt once the hydraulic fluid heats up. All other hydraulic functions work fine. It's already had the tilt, priority bypass, and Aux select valves and solenoids swapped with known working parts, as well as CB1 and 2 swapped. There is no leakage past the seals or packing in the cylinders. Any insight would be massively appreciated. Thanks in advance

Did you all find out the problem. I'm having the same situation. I have also tried what you all recommended and the situation still the same. Is there anything that I'm missing.
Looks like it's Solenoid #5, aux prop/relieve valve
Hi I have the same problem, and only when it's hot too, i swapped the same valves as the other guy. Mine is a 4150 ac truck and there is only 1 lift/ aux pump not double
No piggy back pumps like the old trucks
The pressure is just fine
Pump is double with aux piggy backed onto main. They fail and cant produce enough pressure. You need a new pump
