I just bought an 06 cummins that had a built trans and edge juice w/a hot. Ive had it for about a week and have had no problems yet, tranny seems to be shifting good and firm. This morning i went out and started my truck and came back in for like 10 mins to let it warm up. Went back out there and my edge trans temp was beeping and it was at like 270F and you could smell something was burning. So i shut it right down and pulled the trans dipstick and it smelled really burnt, no shavings though. What could have happened while it was just idling like that??? Heres a list of what i was told has been done:

Protorque billet converter, Trans go shift kit, Rigid 2nd band, Billet band strut, Addition 3rd and 4th clutch, Fulltime lube in valve body, Aftermarket Governor sylnoid, and tightened clearances.
