Experimenting with automatic transmissions. Building them then dogging them to see how much they will take. This helps me when building my racing applications to build the most bullet proof trans I can for my customers. I have run automatics on pure hydraulic fluid, power steering fluid, engine oil, and a mixture of other things. My most important thing though is taking care of my two kids. I am a single father to a 14 year old boy and a 4 year old girl who thinks shes the boss.
