Kevin,

I know there is some reservation, but it is a real gamble if you do not change it. Now, you could be right on the 99 transmission being updated. The sign is the donor car would have a touch shifter with the + and - on D, or no interlock port at the back.

I will give you a quickie on how to get access to the K2 bushing bearing.

A) remove all the torx bolts on the inside outside parameter inside the bell housing. Like the video at 30second mark

B) Remove the screw in the circular electrical connector on the side of the transmission
C) remove the oil pan
D) remove the torx screws holding the valve body, and the valve body itself
E) Remove the two large torx bolts behind the bell housing

F) lay two two-foot 2x4's about 10" apart
G) Lay the transmission the bell on the 2x4's, but the shaft in the center of the 2x4's
H) you may need to bang on the transmission with a rubber mallet right where the bell mates to the body. You may need to pry it alittle on the little half-moon on the bottom
I) then you can lift the rear. Do NOT remove the rear nut like in the video at 2:45. It will be heavy. Have someone help you.
J)The K2 is inside the center of the drum that is on the table.

See this video. it is very poor in quality, but it will make sense. The transmission in the video is a 722.6 out of I4 or I6

Now, I can offer you some pictures of one of the many 722.6 rebuilds I have done, and the 722.6 is the easiest to DIY rebuild of any modern transmissions. I have 800 to 900 pictures on the 722.6, and I can email you a section of them, or you can send me a 16gig flash drive, and I can load all the pictures of the rebuilds with literature, and you decide.
