Burnerman said it all. I just want to stress the part about not over-tightening the bolts. Also, I want to say the last time I did I only used 4-5 quarts to top it off. I would add a couple quarts then start it up in neutral and check the fluid level and add accordingly. You do not want to overfill the tranny. I accidentally overfilled mine when I added a cooler by about a quart. I ended up with a smoke show when ever I would run the Jeep at high speeds then slowed due to the internal pressure blowing the extra fluid out of the vent. I ended up using an electric fluid pump and sticking the hose down the dipstick tube to suck the extra fluid out. A lot of trouble due to my oversight.
