So I had a trans built and installed in my truck from a reputable builder mentioned all the time. 50k mi on this trans and IMO the converter is failing. I am passed their written warranty based on years, but under their mileage. I have a stock injectored truck with a dp chip and tn turbo, it's nothing special. 25k mi was just commuting the rest was mixed driving/towing at about 20k. The whole reason I paid $$$$ for a built trans was so this didn't happen... what's your take? Is it on me to eat the cost of another trans or approach the builder? I'm torn on how to proceed... mostly because I'm f'n broke!
