1996 Jeep Cherokee Shuddering stop

I recently had my transmission checked out due to leaking fluid and a heavy start in the first few gears. The mechanic tightened a loose hose and diagnosed the main problem as bad gear change solenoids. He replace all three and said the solenoids need to break in. Now when I drive it accelerates fine with slightly noticable gear changes. The thing bugging me is when slowing to stop. Just before coming to a complete stop, the jeep shudders. The RPMs drop momentarily but then it idles normally. I'm not so sure if the repairs were done correctly and I dont want to take it to another mechanic if this is normal and will go away.
