SP Diesel Exhaust brake trouble

I have an NADP Heavy Hauler 450 trans with 3 plate converter that has been flawless...up to 17,000 KM (10,800 miles) pulling a 11,000 lb 5er and just running around the city empty. I installed the SP Diesel Performance brake 3 days before my family and I headed down to your good ole USA on a month long camping tour down the mid west and back up the West coast. I played with it before we left to get used to how to work the set points with the cruise and it worked like a dream...right up until our 3rd day on the road in the middle of Nevada, it would not release my converter lock and it would actually stall my truck when I would come to a stop. So on the side of the highway in 101 degree heat I completely removed the unit and all associated wiring (Let me preface that by telling you I'm a heavy duty mechanic and Power Engineer so in stall and extraction of this system was a breeze). All was not well after removal, now my converter would not lock up and trans temps became an issue. Thankfully we were not far out of Reno and AAMCO Transmissions diagnosed it with a burnt torque lock solenoid in the trans solenoid block. 3 weeks and 780 dollars later and still on the road there have been no issues. I wont get into the less than encouraging conversations I have had with SP and their immediate finger pointing everywhere but their module...now that being said they are taking it back for inspection but made good and sure to let me know that even if their module is faulty that accept no responsibility for the damage to my transmission...not sure what to think about that because I still feel that perhaps they are very good at what they do, and even though I'm Canadian I'm all about supporting American designed and manufactured goods! So what I'm after is any feedback from anyone else who has used or is currently using this unit in a 2K 7.3 with the automatic trans. It could well be that it is just pure coincidence that my lock up solenoid failed and it may not even be their fault...but the timing makes it so hard to buy that....and I really do want engine braking with a 40' 5er and now I don't know what to do.
