727 Trans Fluid Capacity

You have to install the converter first then bolt it to the engine. Make absolutely sure you have the converter engaged all the way in (the flexplate lugs should be 3/8-1/2" below the face of the bellhousing) or you will ruin the front pump when you bolt it to the engine. You know you got it right when you bolt the trans to the engine and have to pull the converter forward a little to meet up with the flexplate. I put a qt. in the converter and 5 in the trans. then start it and run it through the gears (wheels off the ground) and fill it to full in neutral. Depending on which converter is used it takes approx. 8 to 9-1/2 qts. Standard Dexron is fine.
