GM 700R4 Diesel, Torque Converter Bolts
Just recently, as I was pulling the transmission, I discovered the 6 count torque converter bolts loosened. I then pulled the transmission out. the Torgque Converter was LOCKED UP. I could find ZERO metal particles in the trans. I added the dots together, that the lossened Torgue Converter bolts, 6 count, had allowed the vibration, created @ 55 MPH, and this is what busted the Hub. Thankfully, no metal was transfered into the transmission. I think I will find another transmission, or just a pump, and use the same Torgue Converter. I cannot see any damage to the hardened steel drive, on the Torque Converter, just the cast Iron Hub, with the vanes in it. Thanks for Reading, time will tell. This Transmission ran GREAT, for close to 2 years, city driving, but it was the 55 mph, freeway speed, that did the damage. My bad was, I did not add locktite or lockwashers, on the 6 count Torque Converter Bolts.
