336E Possible pilot control solenoid ???

Hi Guys

My Cat 336E s/n YCE00244 has lost hydraulics, i initially thought it was the micro switch to the dead man as it was if that got flicked down mid operation, I changed this out but no joy.
Could it be the pilot control solenoid and if so could someone help me locate the correct one, i have the belly plate removed under the swing motor at the back of the slew ring and see a bank of 3 with a nitrogen accumulator (2nd pic) to the right is it any of these, there is also a bank of 2 to my left.(3rd pic) The solenoid plug is out as I was messing around cleaning connections and checking them over.
Any help would be greatly appreciated.

The one close to the accumulator

P is "pilot" lockout
S is "swing brake"
T is "travel speed"
They can be interchanged. I'd measure the coil on "P" first. If open, swap "T" into its place.
Be sure to relieve the hydraulic tank pressure first. By doing so, you will get pilot back but lose travel "rabbit". The only retainers are the 2 8mm headed bolts. Remove bolts and twist left/ right while pulling down.

Thanks for input guys I swapped the travel speed with the lockout solenoid and it's fixed it, il manage with the slow travel speed for a few days untill I get chance to fit the new solenoid.
