If it's similar to a 46re, it's probably the snap ring in the OD. Found pieces in the Durango pan when I did the solenoid deal on it (prior to the 5 spd. swap). You can remove the OD from the trans in the car and replace the snap ring. I used a press but there may be a special tool for compressing the spring. Read up on it if you want to try it. Be very careful with the spring as it has lot of pressure on it and you could get seriously hurt it it gets away from you.
