Honestly I'd love to be in the position to call up Suncoast, DPC goerend say hey, doing a test for a towing/DD TC for 450-500hp truck. Going to hook a 25,000lb trailer to the back of said truck.
Do the following test flat foot stand still acceleration to find how fast does the truck get from 0-55mph, and when does the TTC engage in both T/H and normal transmission operations.
Run each TC for ~10,000miles which would be 5-6 weeks for me which would give me time to cover wide variety of loads and terrain.
Then report back my findings
I'm not in a financial position to be able to do such a thing as per what you have all watched me go through over last 6 months or so..
End of the day transmission is going to need rebuilt soon imo. And right now only thing I've found advertised that meets close to my almost niche needs is either a DPC or a Transtar A7XL
As I said in the other post I'm sure I'd be pleased with either TC in a DD applications and a 600hp truck
