I have my original 5 speed Allison that I am replacing extension housing on at 150k miles. I want to replacethe TQ converter and do full Transgo sk.
Has anyone used Diamond T brand converters. Price is low and Dodge/Powerstroke guys seem to have good reviews
So, I tried them. Put the TQ Converter in the truck. The truck pulls real hard at idle like the TC is locked up. I messaged them and they say "Sounds like there may be something wrong with it. What we can do is have you send it in for warranty inspection and once it comes back as bad we can send you a replacement if the converter comes back as good then we charge a rebuild fee."
I asked them to send another one so I don't have to wait weeks with my truck down and they will not. They also will not send a shipping label. It cost $100 to ship this thing. I would not use Diamond T torque converters.
