With the electronic 4L80E automatic out, we hauled it over to B&M to be gone through, beefed up, and diagnosed. There was a wasted seal in the torque converter, which seems to have been the culprit, maybe due to installation error on our part. Nonetheless, B&M tech Steve Macias tore it down and made it better than stock with high-performance clutches, a new dual-cage heavy-duty 36-sprag assembly, a set of Sonix 1-2 and 3-4 shift spring calibration, and a full set of gaskets and seals.
