99 S80 T6 Transmission Solenoids

[TwoOne]

I recently bought a 99 S80 that was having problems with the transmission, after having the codes pulled it seems like both solenoids 1 & 2 are shot as well as the torque converter solenoid. I know from reading previous posts that there are a total of 4 in there and I would like to replace them all while I'm in there if I am doing three already. The problem I am having is coming up with the proper part numbers for the other two. I know the ACDelco PN for 1&2 is 24219819, does anybody happen to know the numbers for the other two so that I can order them?

Any help is appreciate!

Thanks all,

Louis
