PMP Reconditioned T5 Transmissions. 3/5/2020: TREMEC T5 PARTS UPDATE Tremec is no longer making some T5 parts. We can now build our 370HP units with some aftermarket parts, while we still offer T5s 250HP or 405-500HP 295ratio 4 diffrent ways & a 600HP aftermarket performance gear kit. I'm building a T45 to hold some power, unless I find a cheap 3650(essentially same transmission) T56 has a dog of a first gear. Pros and cons to both, but personally I enjoy a smoother, cheaper, and lighter T45.
