Hard down shift 89 560sel

I have an 89 560sel with 209k miles that is new to me and I do not any history on the car.
I had it in to an independent shop to service the tranny and while it was there to look at the throttle linkage. They drained the fluid and torqu.conveter and replaced the filter. Also replaced the modulater valve??( What controls the vacum to the shift points on the tranny)
Well the hard shift got a bit harder. Shop seems to think it may be the clutch packs from 3rd to 4th. The up shifting is good, a bit firm but good.. The down shift from 4th to 3rd at 60mph is hard!
Couple ?’s #1 could this still be lack of vacuum to the tranny or an adj.to the modulator valve??
#2 If it is the clutch pack. Would it still shift hard when Manually down shifting with the shift lever vers. Stepping on the gas peddle to pass?? When I down shift Manually it is smooth as silk but when accelerating to pass it hits HARD.. Any thoughts or advice would be appreceated Thanks Tom Alpharetta GA
