Slow down over speed bumps
Before dropping the trans, why don't you check to make sure the bolts that hold the case together have not loosed up and caused the leak.
Turk-
My TKO II was delivered yesterday. They also shipped a Pro 5.0 shifter and 3 quarts of GM Synchro-Mesh in the same box and, according to UPS, the total shipped weight was 70 lbs. However, according to TTC's website the TKO II weighs 100 lbs. I haven't actually weighed it yet, but I'm guessing UPS' scales are pretty accurate.
