    Performance automatic transmissions that’s built to take it.

    Whether you have a stock engine or one that's built-to-the-hilt, you don't want to have an automatic trans that just slides into gear. You need one that shifts positively into each gear, especially at wide-open throttle. That's why we sell these performance automatic transmissions from California Performance Transmission. With more than five decades of performance automatic transmission rebuilding experience, CPT transmissions are designed for the rigors of the street and strip. They use heavy-duty clutches and bands along with a complete blueprinting that includes modifications for improved lubrication and increased thrust capacity. The driver has their choice of either complete manual or automatic control of the transmission because of the CPT manual/automatic hi-tech valve body kit installed in each transmission. The TH350 uses the standard gear ratios of 2.52 first, 1.52 second and 1.00 third. The TH400 has a 2.48 first, 1.48 second and 1.00 third. These street/strip transmissions are exact bolt-in replacements for your stock transmission and have all of the heavy-duty features described above.

    Please note, these transmissions have a full 90-day warranty and are then subsequently guaranteed against defective workmanship for three full years from the purchase date. After 90 days, for three years, California Performance Transmissions will completely rebuild or overhaul under warranty, the transmission for $250.00 plus hard parts to the original owner, or $300.00 plus hard parts, to any subsequent owner, if warranty is transferred. This overhaul or rebuild includes a new factory warranty.
