T87 8L90/10L80 diagnostic clutch control commands

Hi All,
Long time lurker, first time poster.
I need the diagnostic commands for actuating the transmission solenoids on a T87
So far i've already figured this out from sniffing another scanner, but it only goes up to 4 clutches as i think it was only made for the 6 speeds
CAN identifier : 7E2
07 AE 34 XX 00 00 00 00
Clutch 1 Control Enable Byte 3 Bit 7
Clutch 1 Control Value Byte 3 Bit 6
Clutch 2 Control Enable Byte 3 Bit 5
Clutch 2 Control Value Byte 3 Bit 4
Clutch 3 Control Enable Byte 3 Bit 3
Clutch 3 Control Value Byte 3 Bit 2
Clutch 4 Control Enable Byte 3 Bit 1
Clutch 4 Control Value Byte 3 Bit 0
It's probably just the next byte for the next clutch controls, I can try sending them and checking with a multimeter, but am currently away from the vehicle at the moment. Am interested to see if anyone else has already figured this out.
