| Post subject: | TC failure and tuned ECM |
Quote: Has the stock TC indeed been proven to be inadequate to handle the increased power of a tune? Who has had a TC failure which was definetly atributible to an increase in HP/torque?
-------------------------------------------------------------------------------- ME. I killed mine with a Predator box in a week. I could hear it slipping a little more each day. It's very easy to repeat. Just hit some on-ramps and give it about 1/4 throttle all the way up. When it locks @50 mph you can hear and feel the torque converter slipping bad. It won't slip at higher rpm's. It also won't slip without the Predator box. Just my observation with mine. Onthehunt and others, will I have a significant increase in TC failure likelyhood by using a tuner such as the Edge Trail Jammer? I just recently purchased a used one and will install in the next several days. Just wanted to know the risks before having fun. I had an Edge Evolution in my F-350 and the difference was night/day. I got these quotes from the GreenDiesel thread but wanted to maintain the pedigree of that thread. |

Yes. The stock tune was too much for the stock torque converter. Install at your own risk. Don't lug the engine. Listen for the slippage at the 50mph lock up. |

I have an Edge and I have put on 50K miles without anything noticeable. With the exception of accidentally bumping it in the 3rd position and forgetting to check and then having the engine shut off climbing long-steep grades on the hwy. It's a bit disconcerting. |

JL Rockies, would the 3rd position be comparable to the InMotion Stage II? Also, what mileage/performance gains do you have in position 2 vs. position 1? Why would engine shut off climbing long-steep grades? I've heard of vapor lock in gassers; is this what you're talking about? |
