89 ranger super cab 4x4 v6 5spd

71k or 171k on it not sure,,,guy bought it from said just put in new clutch,,,i bought it for my son ,,didnt drive it 1st.. kid drives it home n it jumps (grabs) like crazy when he tries to let clutch out ,,1st gear take off only..i jump in n couldnt make it do it..now kid has had truck couple weeks n much worse,,now i cant let it out smoothly either..bout halfway off floor she ll start to garb n jump bang etc..ifn jus drop it n go its fine ,, er if still movin a lil no gas let out then gas shes fine ,,,but stopped if try n let it out smoothly (grabbie ) is best word..she ll jerk the snot outta ya..dont think the fly wheel was resurfced either ..any clues????easy fixes??? only 1st for me but kid seems to make reverse jump to..has he milked it to much n ccuased somthing?>? thanks people for any help

well maybe ill keep werkin n figure it out,,,back her against a pole n burnt clutch n lil bit,,n she were fine fer bout 10 normal starts..let son try it n hes like learnin again,, n she were grabbin a tad bit after few tries..hooked her to pole wid tow strap n smoked that clutch a lil again n fine as he left..so point to me babble is would lean more towards oily plate then a warped flywheel,,now watch the fluid level i rekon (which was full) well unless a course any a yous cats have a thought i could check thanks pappy...shes nawt slippin ..shell spin on gravel n run hard n hold as up against pole,,but as try n release it to go (1st only) bout 1/2 way to out shell jump (grab) like crazee,,better jus ta dump it a lil..n thats nawt right

well the answer is:::: pulled her down n had flywheel resurfaced ,,,but the dang thing did same thing..looked over evo thin real close aagain n found the flippon tranny mount real wore ,,,jambed a board in there n walla no grabby noise...then grabbed new mount n flipped in there n she be good..thanks fer lettin me talk ta meself ,,hope this babble do help some cat some day paps
