any help would be greatly appreciated ..thank you!!
1) Disconnect battery
2) Drain trans fluid
3) Remove dipstick
4) Remove driveshaft
5) Remove starter
6) Rotate flexplate via damper bolt until converter bolt is revealed on passenger side of oil pan. Remove converter bolt (clamp vise-grip to ring gear to lock flexplate if necessary).
7) Repeat step 6 two more times
8) Remove bellhousing bolts
9) Support trans with jack
10) Disconnect trans crossmember bolts from car
11) Slide trans back via jack. Wiggling but steadying trans until trans comes off dowel pins.
12) Slide/lower jack until trans is far enough to slide out converter. Slide out converter.
13) Put approximately 2qts trans fluid in new converter (size dependent).
14) Slide on new converter until it seats. Spin, wiggle, and push until seated.
15) Use zip ties through converter bolt hole to fasten converter to case (shifter linkage works)
16) Reverse removal
17) Fill with fluid. Check level while running.
18) Break in new converter
19) Mash throttle and smile
I may have missed some stuff in there but you get the gist. A Haynes or Chilton manual for a 4th gen will give you an idea, but it's pretty close even on a TH400.
