VB swap is as easy as dropping the pan and removing a few bolts
doesn't even require transmission removal
For torque converter swap the hardest part is taking the transmission out,
which I guess isn't really that hard, just tedious and time consuming.
Only thing that gave us a little trouble was reaching to the top of the trans
to disconnect the stubborn o2 sensor connectors before we could drop the exhaust
I'm sure there are some shortcuts but this is a copy and past from the Dodge Service Manual.
Here are the procedures for trans removal:
1. Disconnect the negative battery cable.
2. Raise and support the vehicle
3. Remove any necessary skid plates
4. Mark propeller shaft and axle companion flanges for assembly alignment.
5. Remove the rear propeller shaft
6. Remove the front propeller shaft, if necessary.
7. Remove the engine (1) to transmission (3) structural dust cover (2).
8. Remove the exhaust support bracket from the rear of the transmission.
9. Disconnect and lower or remove any necessary exhaust components.
10. Remove the starter motor.
11. Rotate crankshaft in clockwise direction until converter bolts are accessible. Then remove bolts one at a time. Rotate crankshaft with socket wrench on dampener bolt.
12. Disengage the output speed sensor connector from the output speed sensor
13. Disengage the input speed sensor connector from the input speed sensor
14. Disengage the transmission solenoid/TRS assembly connector from the transmission solenoid/TRS assembly
15. Disengage the line pressure sensor connector from the line pressure sensor
16. Disconnect gearshift cable (1) from transmission manual valve lever
17. Disconnect the transmission vent hose from the transmission.
18. Support rear of engine with safety stand or jack.
19. Raise transmission slightly with service jack to relieve load on crossmember and supports.
20. Remove bolts securing rear support and cushion to transmission and crossmember.
21. Remove transfer case, if necessary.
22. Disconnect transmission fluid cooler lines at transmission fittings and clips.
NOTE: When disconnecting the transmission oil cooler lines, it is necessary to replace the line clip that is located on the oil pan stud. The retention force of the clip is severely degraded upon removal.
23. Remove all remaining converter housing bolts.
24. Carefully work transmission and torque converter assembly rearward off engine block dowels.
25. Hold torque converter in place during transmission removal.
26. Lower transmission (2) and remove assembly from under the vehicle.
27. To remove torque converter, carefully slide torque converter out of the transmission
Here are the steps for tc removal:
1. Remove transmission and torque converter from vehicle.
2. Place a suitable drain pan under the converter housing end of the transmission.
CAUTION: Verify that transmission is secure on the lifting device or work surface, the center of gravity of the transmission will shift when the torque converter is removed creating an unstable condition. The torque converter is a heavy unit. Use caution when separating the torque converter from the transmission.
3. Pull the torque converter forward until the center hub clears the oil pump seal.
4. Separate the torque converter from the transmission.
For 4x4 its a little more work if you dont have a fully equipped shop with a lift and a trans jack.
We had to remove the transfer case to make the transmission easier to handle. (just used floor jacks)
Top up the new TC as much as you can with ATF+4, just under half full when stood upright.
When installing the new TC it's Very important to make sure it is fully seated, turn push and rotate again until you get the second "click"
Ask Kurtis about what happens if you skip that one lol.
Great youtube vid explanation on Torque Converters:
