Hi Chuck , I am assuming it is an SB55 TC ( Torque Convertor). The hydraulics is not connected in any way to the transmission so it looks like you have 2 different issues. Firstly if the hydraulics are slow to respond I would check the hydraulic oil level and indeed main filter. Some models had what they call a PFD (Preferential Flow Divider) located just below the Dan Foss steering unit. This diverts hyd fluid to either steering or hydraulics depending on demand. It is a straight forward job to check the main hydraulic pump should you wish to ask etc.
As for the transmission. assuming as I said it is an automatic transmission this could also be fairly easily checked.
I did not see your initial message as I rarely log on but if you reply I will keep a look out etc.

Regards
