Just got my new th400 in the car and it seems to be doing some crazy stuff. when in park and neutral it idles fine but if i rev it it seems to have a load on the engine..Is this normal? the next crazy thing when put into first gear the back tires turn over a couple of times then they stop.i can give it gas but they aren't going anywhere...what the heck is going on? i shift to second and the tires begin to turn. i shift to drive but i can't tell if the trans is going into drive or not but the wheels are turning. i have double checked the linkage on the quarter stick and it is right...the trans is a manual reverse valve body with a brake. any help will be greatly appeciated as i wanted to go to the track tomorrow....................thanks Bob
