I hope you get some feedback specific to Suncoast's products and service.
Although there are many to choose from, the overwelming favorite around here is Diesel Transmission Technology. Bill Kondolay's (DTT) way of doing things has brought out some "spirited-dis-agreements". You should easily find plenty of reading with the search function (above).
To summarize, the stock lock-up clutch is the weak point in the Dodge transmission. Most transmission companies sell a heavy-duty replacement to prevent slipping. However, in high, horsepower applications, this can cause break-down in other areas of the transmission. Bill K. sells a very efficient fluid coupler, and uses it under load, rather than the lock-up clutch. It yields virtually the same power output, yet will "give" before further damage is done.
Bill's strongest point is his service, 7 days a week. He is great to talk to for advice, will personally help trouble-shoot any problems (even if it's not his product), and will stand behind his products like no one else.
Unless the price/convenince is drastically different, you really should look into his T/C, VB, etc. Give him a call with any questions, about his products, or others. You won't be disapointed.
Good Luck, and may you be happy when the smoke settles.
