MHPs Custom Stall Converter for 7G transmissions works on all 7G equipped MB/AMG vehicles (except the SL63 and 2010 E63 with MCT) and is available in custom stall speeds based on your application. By using a stock MB core with custom billet internals and a completely redesigned stator fin design we can achieve OEM or greater reliability levels while vastly improving both "off the line" and "at speed" performance during both part and wide open throttle. Customers can expect greatly improved low end and midrange power and throttle response. Converters are available outright (no core supplied or exchanged) or with core exchange. We will charge an additional $1550 core charge that will be reimbursed immediately upon receipt of your OEM MB 7G stall converter. Core Exchange: $1850 shipped + Core Fee ($1550) Outright: $3250 shipped Please email mike@bwoodyperformance.com for more information or an international shipping quote.
