this is why i always  remove the tcase befor installing trany,  but yea wiggle and push,  did you use the alignment tool when  installing the clutch or did you remove the clutch,  you really should replace it and the pilot bearing when tranny is out


what i have done in the past with full size truck trannies toy trannies only weigh 100lbs give or take   wimps

anyway  i use a 2 inch ratchet strap toss, it over the cab andsecure inside right above tranny shifter,      then another smaller strap thru the shifter hole and around the tranny,   if the seat is out a small hand wich works really good

i have taken one fork off a forklift and a big chain but that was on a 12 speed mack tranny
