IMPORTANT NOTE: Turbocharged cars and race cars equipped with lock up converters FULL SYNTHETIC is recommended. We recommend you don’t use a thick fluid due to the shift, and pressure solenoids.ĩ00 HP OR LESS - Recommended Fluids See full synthetic notes listed belowĥ0/50 Mix of Dexron 3/Mercon and Ford – Type Fĩ00 -1,500HP - Recommended Fluids See full synthetic notes listed belowġ,500HP Or More - Recommended Fluids See full synthetic notes listed below Synthetic fluid is acceptable but not required. Try to use a good name brand oil company, Please no economy store brands. If you have an overdrive 4L60E-4L80E Transmission it is best to use Dexron 3,5, or 6, Mercon is recommended. Synthetic fluid is highly recommended see full synthetic notes listed below. Synthetics are acceptable but not required except when running a turbo charger or using a race transmission with a lock up torque converter. NOTE: Transmission has approximately 1 quart of fluid left in transmission after dyno testing this will count as part of total fluid volume also if your transmission has a custom fabricated pan modified for clearance at the rear of the transmission it will have about 1 quart less capacity. For example, if you have an 8-inch converter it will take approximately 10 quarts of fluid, if you have a 10-inch converter it will take approximately 12 quarts. On a Th400 with a 2quart after market deep pan, the total amount of fluid, measured in quarts, that it will take to fill the transmission will approximately be 2 quarts more than the number of inches of your torque converter.

For example if you have an 8 inch converter it will take approximately 8 quarts of fluid, if you have a 10 inch converter it will take approximately 10 quarts. On Power-Glides the total amount of fluid, measured in quarts, That it will take to fill the transmission will approximately be the same number of inches and your torque converter.
