DESCRIPTION

Advance Adapter

This custom flex plate kit is designed to adapt the Gen III / LS series to the GM TH350, TH400, and 700R4 transmissions. The kit includes a flexplate, 11mm flex plate bolts, crank spacer, collector gaskets, stock exhaust manifold rings.

Gen III / LS Engines

The new style Gen III / LS series engines (4.8, 5.3, 5.7 LS1, 6.0, 6.2) all have the same crank stick out which is .400” closer to the block than the old 350 V8. The Gen III / LS series crank bolt pattern is different than any other GM crank as to the bolt pattern on the flex plate. Only Gen III / LS series flexplates fit these engines!!!

Since a Gen III / LS series flexplate only fits a Gen III / LS series and the engine crank is recessed .400”. There are a few unique things about the torque converters that bolt to the flexplate. The spacing of the flexplate from the back of the block is the same as early GM blocks. The flexplate is dished out .400” to compensate for the crank. The differences come into play as to the bolt pattern of the torque converter to the flexplate and the snout length of the torque converter.

How do we adapt TH350, TH400, 700R4 to a Gen III / LS series engine? We offer a custom flexplate to fit a TH350, TH400, 700R4 and a crank spacer that compensates for the shorter engine crank.
Note: This Advance Adapter kit does not work with a 6.0 engine with cast-iron cylinder heads.

go to dakotadigital.com and get one of their encoders for your application. If you dont see it on the site call them and they'll fix you up.

its an electric motor that will spin the cable drive. It plugs into the transmission.
