Torque converters are outrageously expensive for the 6l80. Those will be out of my budget unfortunately.
IF you don't replace the converter with the rebuild, you are doing yourself a disservice. The oem
converters fail around 100K, depending on care and usage. If the converter clutch fails, you will be rebuilding the entire trans again.
Stock type converters that are a better design can be had for $300-$400
