Blessed Performance has the SunCoast Category 1 450HP 47RE Transmission NO CONVERTER.
This new SunCoast 47RE transmission is rated at 450HP. This is a perfect upgrade for someone towing and hauling or who has a slightly modified vehicle.
There are several key components in this transmission that are upgraded to not only improve performance, but also restore hydraulic integrity.
The factory accumulator piston, being plastic, deteriorates over time, causing it to crack or simply break in many pieces. It is also not uncommon to see this accumulator piston cross-leak within the bore, which is the reason they engineered this piston to be a four-ring sealing piston, versus the factory two-ring. It is standard in all of the SUNCOAST units to replace this factory piston with an improved billet piston to not only restore hydraulic integrity but to improve reliability, as well.
To alleviate the issues with the factory intermediate band circuit, they address many facets of the all-too-common second gear band burn-ups on the 47RE Transmission - the first facet being the servo that applies the intermediate band itself. SUNCOAST replaces the factory cast servo with a larger billet servo that has more apply pressure and improved release. This servo also is improved to a four-ring servo, versus the factory two-ring, with the primary sealing ring being square-cut teflon and the secondary being an o-ring.
