You could still shim the springs on the 4T60, could you not? Not sure how much effect it would have, but it should do something...

Dan..how hard was it to remove that section you show on the table from the three tubes?

I removed the 4 botls holding it in place, then slowly wiggle it back and forth not forcing it. It will slowly work off the tubes. dont pull hard, just a little while you twist it. Took about 2 mins to do that.

Mine actually came right off because the two tubes actually swing down once you undo the bolts that hold the modulator to the rest of the transmission. The Tube that goes to the differential (i think?) had to be wiggled free first though.

For those who have done this, how much fluid did you have to put back? The manual says 6 quarts for a pan drop and drain, and a total capacity of 11 quarts. I also removed the filter and shift modulator. I have added 6.5 quarts, it'* on the stick but a little below the line. I will need to go pick up some more. But how much?

2-3 Quarts to be on the safe side and you should have some extra (or I would think so).
When I dropped my pan (pre Intense trans) to change the filter it took 7-7.5 quarts to bring the level up.

Thanks, that'* just what I needed to know. I think I'll just pick up another gal jug.

6 liters is all it should take. Remember that the level is checked with the oil hot at above 160 F

The temp was at 150 the engine was at idle and the trans was in park. It was still only at the tip of the stick. I've been adding only 1/2 quart at a time, then checking in a day or two, if still low I add a little more. It'* possible the level was low even before I installed teh shift kit, I don't remember checking it. Because it'* at the stick I'm not worried about running low, but I also dont want to over fill it.
