Punch Powertrain VT2+

Transmission general data

The CVT VT2 transmission was released in 2009 and was offered to numerous carmakers (Brilliance/BYD/Chery/Geely Emgrand/Great Wall/Tengyi/Haima 3/Freema/Hyundai Avante HD hybrid/Huandong /Toyota Vitz).

CVT transmissions VT1 and VT2 have a reliable design (with a significant safety margin of transmission components) with a push belt. For many years, maintenance and repair services for this CVT are limited to change of oil and filter, and later – replacement of the Bosch belt.

The software of VT1,2 is designed to spare expensive cones at low speeds, when the belt and surfaces of cones operate very intensively. The cones have wear-resistant coating of operating surfaces implemented with the help of space technologies. These cones cannot be rebuilt and are not supplied to repair markets. The valve body filter in the VT2 transmission is based on Jatco solutions.

Rare overhauls accompanied by reassembly of spare parts, the wear of which leads to pressure losses on the friction clutches and their consequent wear, require the repair kit of gaskets and seals. Repair specialists prefer to use Precision repair kit.

Experienced transmission repair specialists, who work with VT1 and VT2 transmissions, change the filter and ATF as often as possible, because it is extremely hard to find spare parts for these transmissions. While changing the filter and ATF specialists usually check the chain (belt) for wear of the protector and in case of any suspicion of wear – replace the belt. The 30-40% wear of the belt teeth increases the risk slippage (metal-on-metal), even with the common (not sports) acceleration to outrun the truck ahead.

If the surfaces of cones have tears or "pits", then specialists advice to replace the CVT instead of its repair. Generally, the VT2 transmission is considered to be "invincible” under the condition of proper maintenance. Today, it is one of the best CVTs on the market.
