I really like the TCS converter that I have now. I went thru an ATS TQ converter with in about 7 months or so. They rebuilt it for free, but I sold it as soon as I got it back. I put in a TCS about 6-7yrs ago and while running 238/80s in front of it the entire time. I've never had one issue with it. I'm on my 4th transmission as well. So as you can see, I've been hard on my truck. I now have 300/200 in front of this trans, so let's see how the TCS does with this. It suspect it'll do just fine though. I spared no expense on the trans and in fact, over built it w all 3 billet shafts and other goodies to go along with it.
