Wow, thats good to hear, I was kind of wondering the same thing, even though Im not even close to you in mileage (40k), but I do plan on keeping the truck a while so it would be reassuring to hear that I wont need a new tranny until it hits 150k or more .

70K on the first one, 1K on the second one, 70K on the third one one.

IMO unless its a built tranny it can go at any time. Watching your temps is one of the most important things. Keep them in check. A good Valve body can help it last a bit longer as well. Some people can get 200k out of them some people get 10k out of them

That all happened in the low 300hp range. I would not even think of the power level I am at now on a stock trans

60,000 for my first one
