sprayed99 Posted May 7, 2009 Report Share Posted May 7, 2009 The transmissions in our trucks are the weakest link by far. If you're in the 13's you are at the limit of a stock transmission. Just because these guys "built" your transmission doean't mean they BUILT it. You need an upgraded shell, better bands, higher pressure and more cooling to keep one of these going and if you pull all the TM even on a stock truck a truely built transmission won't hold up forever. I'd ask what all components they're putting in there and compare that to an FLT or Raptor and see how it compares. dont touch the pressure tables!!!!!!!!!!!!!!!!!!!!!!

sprayed99 Posted May 7, 2009 Report Share Posted May 7, 2009 to bad you dont have HPT. who tuned the truck???????? Quote Link to comment Share on other sites More sharing options...
ss454327 Posted May 7, 2009 Report Share Posted May 7, 2009 dont touch the pressure tables!!!!!!!!!!!!!!!!!!!!!! Nobody told him to touch the pressure tables...that's not what I was talking about. He talked to my cousin and that might be what's off in his tune though. His sig shows who tuned it but I'm not sure if he was tuned before the built transmission or not. I've seen people add line pressure on mostly stock transmissions but once you upgrade internal parts you shouldn't be adding anything secondary.

vmaxman Posted May 7, 2009 Author Report Share Posted May 7, 2009 thunder racing did the tune b4 the stock tranny went and after that i never had it tuned again and i believe they had the line pressure turned up thats what i am thinking is doin the damage Quote Link to comment Share on other sites More sharing options...
vmaxman Posted May 7, 2009 Author Report Share Posted May 7, 2009 they guy at the tranny shop said the shifting was a little erratic and said that he was not going to take the shift kit out but tune it down a lil bit Quote Link to comment Share on other sites More sharing options...

I'd also get with Jason soon to have him at least look over your tune for problems. Quote Link to comment Share on other sites More sharing options...
vmaxman Posted May 8, 2009 Author Report Share Posted May 8, 2009 im am goin to try to get him to tune it next weekend Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted May 8, 2009 Report Share Posted May 8, 2009 When I had my transmission rebuilt, the builder told me to have all pressures set back to stock settings because the modifications he was making to the transimission and the components he was installing would create the firmer shifts with greater durability. I had zippy set everything except TM back to stock on my tune, the truck shifts firm, and almost 20k miles later behind forced induction and I have zero issues. He also told me to never increase line pressures through the pcm as it causes very rapid pre-mature wear or failure. The guy msut have believed in his ability because he gave me a 2yr/24mo warranty.
