thanks for the info. A buddy of mine got his t56 built from tick performance, not texas drive train. I was wrong. I'm liking what you say about the magnum from D&D.
I put a WOT box in my truck so power shifting is much easier on the trans. I always found it took some time for the syncros to work even on the 1-2 shifting.
I researched the tr6060 but it seems the t56 hold power and abuse in general better although the tr6060 is a smoother trans.
Considering i picked up a used viper spec for around 1500a few years ago, there's no way id pay near 4k for any stockish trans. Viper spec is cool and all but they sure dont shift as well as the terminator. But i got it for the strength. That didnt last either. It was used and it did take a lot of abuse so i cant complain.
The only way to get a T56 to shift smooth at high rpm is to retrofit a housing and use the GM gear set with triple cone syncrhos on the 1-2 and 3-4. That or go with the rockland standard gear T56, which is almost $5,000....The ultimate downfall of a T56 is the gear width as mentioned above. The 30 spline viper shaft is basically unbreakable, the 31 is stronger and 32 is even more robust. Basically a "viper spec" trans, is a stock trans with a 30 spline output and 26 in. It's not going to handle any amount of extreme power. I mean hell, the Z06 trans is rated to almost 750 ft lbs., 200 more than a viper spec. The only real benefit to running the larger main shaft is the higher spline count on the slip yoke, which is where you usually get your driveline failure launching repeatedly. The splines will twist, or the yoke can shatter. The 26 spline input is also rarely damaged by power.
