(For Twin Ultras)

As many of us know, the torque converter reactor endplay must be between .010 and .017, and the manual says to adjust this by replacing the "first turbine thrust washer" 3.6233 to one of a thicker size.

However there are 3 thrust washers total in the assembly:
- 3.6233 (above) between the clutch housing and first turbine
- 3.6163 between the first turbine and reactor
- 3.6173 between the reactor and pump

Since of course the pump is bolted to the clutch housing, these 3 are sufficient to keep everything "spaced apart".

Is it ever necessary that the two other thrust washers wear enough to need replacement? The parts book indicates only up to 0.48 oversize on the 3.6233 washer.
