Did I dun did fargged up?

[chickenwing]

Well got done with my wiring. Finished the lil details holding me up for the maiden start up of my Goodwrench 350. Fired right up with just a bump. First time one came to life for me with no leaks. It was a good omen. Made extra sure nothing was in immenant danger, ran her for 20 mins at 1900-1950 for cam break-in. Everything as advertised. Bled my brakes this morning, put in the seat. Went for my maiden voyage.....a 1/4 block. Very heavy vibration, slow to accelerate. Then, Oh My God! I realized I had'nt topped of my tranny fluid! It took 2 quarts. Vibration still present after fluid service. Idles fine, have not hooked up a tach to see the range. Suspect it is vibrating between 1100-1700 rpm.
So whatcha think. Did I blow up my tranny?
