Great news for the 545 transmission!!!!!

Here at our shop, we have the nastiest supercharrged AWD GMC Syclone pickup along with nastiest 4x4 Ram. Both eats transmissions for kicks and both will not except a 4L80 swap since there's no room for a 4L80 in the Syclone and it would cost me a small fortune to replace and mod my front drive differential.

So...Here come's Sonnax to the rescue. Gregg Nader himself, a Guinness with transmissions and the director of Sonnax High Performance, flew out and spent the better part of last week helping us solve our issues. As most of you know, Sonnax is world known in the transmission business and that same company makes the line pressure booster that some of us run to increase transmission line pressures on the 545.

First off, he help us re-build and blueprint a 4L60 for the Syclone, which btw will be called the Superstreet Performance 4L75, but you'll just have to wait a tinge before I can release any info for my 545 build. Trust me, it'll be worth the wait. And the bright side is, is that any reputable transmission shop will have access to these parts once they're released.

Don't fear the 2nd gear prime downshift no more.

There not available yet so I don't know the price. The new parts must be tested first, so that's where I come in.
