I have recently purchased a 89 4x4 CTD with the 5 speed getrag, i turned the pump up a little and now it seems that i need a clutch, what are my options, can i use a clutch out of a nv4500 or 5600, what is the difference. also it hung in third gear yesterday, what would cause it to hang and what do i need to do to fix this prob. thanks in advance for any advice.
