2001 1/2 and 2002 Stang Tranny

[4.6runner]

ok guys, i was getting frustrated reading all this so let me set it straight......borg warner built the t-5 tranny until the arrival of the t-45 in 1996(also borg warner). In 1999 the company TREMEC began making the T-45 TRANSMISSIONS different company, same thing...... the tr-3650 came sometime during the mid 2001 production, also made by tremec. hope that helps. also, the newer 3650s used a larger clutch.
