Just had the Suncoast installed two weeks ago, completed over 1000 miles on it last weekend through mountains, back roads, dirt trails, creek crossings, etc. Not one bit of shutter or slippage encountered! Was running Stage II Hot tune and averaged a little over 25 mpg over all driving conditions.
Loaded Stage III Max tune yesterday and tested on highway, tried to make it shutter or slip in lockup between 55-65 and could not! TC held everything I threw at it!
Next test is to put a loaded trailer behind it and test!
I did have the front pump and Transgo Kit installed as was recommended by Suncoast and by my local transmission specialist who did the install. He stated there are parts in the front pump that do wear out, so I had it replaced.
I own two Suncoasts now, one in Dodge Cummins, other in Jeep CRD, they are the best there is IMHO.
This thing is a little race car now!!
