Proper torque converter seating is critical before installation. Fully engaged, checked, and set to avoid pump damage and shifting issues. Take the time here and save problems down the road 🛻💨

If you have a lathe, a bridgeport and a mcmasterr carr account, you can do just about anything. I wasn’t fond of the three legged “spider drive” attachment that was included with the transmission dyno - it lacked precision in the concentricity and runout department. Necessity is the momma of invention - I machined a Cummins crankshaft simulator. This way I can bolt up any flexplate that is used behind a Cummins engine and have a drive that runs seamlessly.
