I'm in the same boat you are. I've got almost the same miles and my tranny was rebuilt due to what I believe was a mis-diagnosed vacuum issue, due to what was written on the repair bill. I need to adjust my vent valve on top of the ip because all the shifts are a little soft but the 2-3 tends to run away a little bit more. I'm due for a fluid/filter change in about 8k miles, sometime in early spring and I'm going to install the K-1 spring kit then.

Is the K-1 not replaced or updated in a rebuild? Could it be worn out alread, in say, 50-70k miles?
