1996 Ford Ranger

If its moving before the clutch job then no problem with the tranny.

If the clutch does not release completely when the clutch pedal is fully depressed, the disc will continue to turn the input shaft. This may prevent the driver from shifting the transmission from neutral into gear, cause grinding when the gears are changed or cause the engine to stall when coming to a stop.

A clutch that will not release may have a misadjusted linkage, a broken or stretched release cable, a leaky or defective slave or master clutch cylinder, air in the hydraulic line or cylinders, or corroded, damaged or improperly lubricated input shaft splines. Other problems include a worn pilot bearing/bushing, a worn bearing retainer, bent or worn release fork or pivot ball, bent clutch drive straps, bent or distorted clutch disc, an improperly installed clutch disc or clutch, or mismatched clutch components (new installation).

Try rebleeding it from the clutch slave and adjust the free play and pedal height and see what happens-don't work I'm afraid you have to go back in and investigate.
