on the 5 speed you have to do a full Transgo shift kit, and you have to drop the trans to do it, and it wont cure the issue, maybe bandaid it for a while

The converter and clutches need to be replaced at the same time, so while you have it out to do the shift kit you might as well rebuild it too, and get a new converter, the stock converter is known to be weak when you apply more torque
