700R4 Failure

[todd99]

I need your help.

The 700r4 in my truck failed after about 8,000 miles. I lost 3rd and 4th gear, so I am assuming that the clutch pack is shot.

What I am trying to figure out is why did it fail so quickly?


I have three theories:

1. improperly adjusted tv cable

2. at somewhere between 400-500hp it may be too much motor

3. improperly wired tcc solenoid - my reason for this is that when I bought the transmission the guy that rebuilt it swore up and down that it only needed to be connected to a keyed 12v source. Saying that no switches were necessary and the transmission would unlock on it's own. Everything on the internet says contrary, but he has been building for transmissions for a long time.

So what do you guys think?
What is your opinion on the tcc solenoid?
And lastly at 8,000 miles do you think I need to replace the torque converter when I rebuild the transmission?

-Thanks
