DDMWorks original Product!
We have seen stock transmissions start to have an issue at stock power levels with long term driving on them, let alone at higher power levels then stock. So we are the first to come up with the ultimate upgrade to the stock 5 speed transmission. This T56 conversion swaps in a 6 speed T56 transmission from a Pontiac GTO with a LS2 V8 into the Pontiac Solstice or Saturn Sky and gives you an almost indestructible transmission in the Solstice and Sky.

This conversion can be completed on either an automatic car to convert it to a manual, or as a straight upgrade to your stock 5 speed. Also available as an option is to have your stock driveshaft modified, or a new lightweight aluminum driveshaft for the conversion. Our conversion kit includes the following parts -

  • New GM Clutch Slave Cylinder
  • New GM Pilot bearing
  • Slave Cylinder spacer
  • New GM flywheel bolts
  • New DDMworks lightweight flywheel
  • New DDMworks Clutch kit
  • New DDMworks custom bellhousing adapter
  • New VSS plug
  • New backup switch
  • New T56 shifter adapter
  • New T56 shift ball
  • New DDMworks Custom T56 backbone 1/2" thick
  • All new associated hardware needed for install

This is everything needed to convert your car from the stock 5 speed to the much stronger T56 6 speed transmission found on in many of the V8 swaps into the Solstice/Sky. You can choose to source your own T56 transmission from a 2006 or newer Pontiac GTO, or purchase a new one as an option listed above and have everything delivered together. Other T56 transmissions can be used with our kit, but will require the rear shifter mechanism from the GTO, the rear shifter mechanism is pictured above, the GM part number is #92147175. We also offer this as a conversion service here at the shop, please email or contact us for current price of installation.

If converting an automatic car, you will also need a new clutch pedal and brake pedal and a few other components. Please contact us and we can get you the additional parts needed.

This kit is built to order and typically takes about 3-4 weeks after ordering before shipping.

Shipping cost is not included, call or email for freight shipping costs if purchasing the T56 from us. If you are only purchasing the conversion install kit that kit can be shipped via regular UPS shipping.
