    Put in an extra 1/2 quart on top of that.

    BTW, I noticed you put in a new radiator. Did you flush the trans cooler? Sometimes those have debris in them from the factory.............

    I never did figure it out, I completely flushed it, put in a new filter, checked the solonoids, and put new fluid in. It is now only going into first and slipping like crazy in the gears it is trying tob go into. I have found a local trans shop that think I can trust to do a good HP build for me, so as soon as I get the funds together I will go that route.
