Im jus curious. Ive got a probuilt and im going on 3 yrs with it. its still shifts as good as the day i bought it. I ran a best of 12.4@111 with 1.6 60ft this is my daily driver so its seen quite a few miles. how long has everyone had thier probuilts? I went through 5 other trans in a 1.5 yr span 2 of which were fresh rebuilds 1 broke first time down track while going through the traps i almost listened to my friends and put th350 trans in. before i got a probuilt. Probuilt is an awesome trans and dana is a great guy to deal with. how fast are you running in 1/4? im running 383 and wanna spray but i need a 12 bolt before i do that. Keep up the GREAT work Dana!!!!

p.s im not trying to give dana bad press eveything is breakable but I have NEVER heard of anyone breaking one!

Haven't broke mine yet, I've got 2 years on mine so far with no hint of slippage or failure.

I have had mine in since January and I absolutely love it. I have recommended Pro-Built to all of my friends.

And I thank Thirdgen.org for steering me to Dana's shop.
