Another thing that some people miss is the correct way to fill the Columbia with oil. IF you read the instructions they spell it out. I put the car up on Jackstands LEVEL. Run the car in the gear specified for the time specified then quickly get out and put in the amount of oil specified. The reason for this is that you are filling the inside of the Columbia where the sun gear is and before the oil runs back out to the banjo, you need to top it off. And as specified, USE THE COLUMBIA FILL HOLE, NOT THE ONE IN THE BANJO.
You also don't want to check the oil level in the Columbia without doing this same procedure . I know of more then one rebuilt unit fried due to not following the proper procedure for filling it with oil.
