Another bad one
4000 miles on mine. Customer service what customer service. If it goes down I hope you can be without your truck for a couple months. I was punked by firepunk.
I guess I got a bad one !
Replaced my 05 transmission with this one. I have 76 miles on it, it shuttle shifts , the transmission temp runs over 205* unloaded also I get a horrible vibration under 1000 rpms. Now I have to pay the shop to remove the transmission and pay return shipping. My truck will be down for 2 weeks minimum. My ats in my powerstroke is a much better transmission. I know no one is perfect but over 600.00 to fix their mistakes. Read the fine print on the warranty !!
Love the firepunk
I've had the street and track transmission in my 98.5 cummins for about 3 weeks now and it's been awesome. Has a firmer shift than it did before but that's to be expected. Overall, I would recommend Firepunk to anybody looking for a great transmission!!
