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 have 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.
This conversion can be completed on either an automatic car to convert it to a manual, or as a straight upgrade from the stock 5 speed. Also available as an option is to have your stock driveshaft modified, or a new lightweight aluminum driveshaft for the conversion. The base kit includes the following parts -
New GM Clutch Master Cylinder
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 swithc
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 our V8 swaps into the Solstice/Sky. You can choose to source your own transmission from a 2006 or newer Pontiac GTO, or purchase a new one as an option listed above and have everything delivered together. 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.
The install kit starts at $3150 and goes up from there depending on what options you pick.
Installation is about the same as doing a clutch swap on the car, if converting a manual car, obviously an automatic takes a little bit more with doing the pedals and some other wiring needs to be done.

We have done some of these conversions, here are some pictures from the installs:
This is a picture of the custom backbone that comes with the install kit. It is 1/2" thick and unique for this conversion, although very similar to the one used on the V8 swaps we do.
Picture of the custom bell housing adapter being fit to the engine first, then the transmission gets bolted to it in place
