B1 clutch pack bushing , A/T 09G

If B1 pack fails, there are problems with 2-6 gears switching:
- slippage shifting between gears
- long gear shifting 

To eliminate the malfunction , experts of Maktrans company developed a repair bushing. The bushing is made of an aluminum alloy identical to the material of the valve body. The shape and dimensions completely repeat the internal design of the pack B1 channel. Quality of manufacturing corresponds to the norms of original repair kits thanks to the use of numerically controlled machines.

The bushing is installed in the prepared channel. Preparation of the channel is carried out by reamers from the initial diameter of 13 mm to the diameter of the repair bushing 15 mm. The step of applying the reamers is 1 mm. After increasing the diameter of the valve channel, the bushing is pressed in with minimal force and reliably fixed in the valve channel of the converter lock up. After the repair of the valve body, the gearshift is carried out in the normal mode, the slippage and fuzzy switching dissappear.

Recommended reamers:

- 14 mm reamer

- 15 mm reamer
