Before I put the sonnax on my trans, when I would cruise the hwy, whenever
I tried to speedup while in lockup, it would feel like my engine was
free revving and the rpm would shoot upwards as if the engine divorced itself from the rest of the vehicle.
Then after about a second it would feel and sound like someone hit me in the back then gears would engage and the vehicle would takeoff.
But ever since I put the sonnax in about 800 miles ago, it has only happened
once .

I got my Sonnax the other day and I tested it out. It seems to shift faster and a little firmer than stock, but not to harsh. I like the way it shifts. Lets hope it stays like this and the PCM wont learn it.
