727 Fluid Type

One of the other things I have found is the fluid level is suppose to be at the add mark Cold, and between the add and full mark Hot.
The best priced RTF Racing Transmission Fluid I could find is TCI RTF 18.95 for 1 gallon at Summit Racing part number TCI- 950601 or for 55.95 3 gallons part number TCI- 950600. They had many more Dexron/mercon fluids as well, but all priced very high, from Lucas to Redline, to Royal Purple, B&M, etc.
