88 ford bronco stuck in low gear

pulled out some bushes with my bronco in 4wd low and the shifter in low 1. now it feels like it's stuck in low gear even in reverse it feels like its in 4wd low but when I gun it only the back wheels spin so I belive it is in 2wd..and it only goes about 25-30 mph before it winds out .any sugesstions what the problem may be?

Check the fluid level in the clutch master.
