I was talking to a guy tonight that said it was possible to install a flywheel on an automatic transmission. Is this true, because I thought they were only for manual transmissions? Can anyone answer this question? Thanks.

 

Automatic transmissions do contain a flywheel.

 

and its stuck on the torque convertor

 

As quoted from Stillen catalogue...

With reduced weight (stock is 17.5lbs., this beauty weighs in at just over 13lbs.), less power is needed to overcome Flywheel inertia. The result is a quicker revving motor. The Maxima's stock Flywheel is essentially the automatic's torque converter plate with weights added and is not ideally suited for performance applications. Uses the factory timing ring/gear from stock unit.

Applications:
95-01 Nissan Maxima (Manual Transmissions Only ), Part #451065
96-99 Infiniti I30 (Manual Transmissions Only ), Part #451065

This is the 2002 catalogue and was mailed to me Feb 7, 2002

 

Its called a flexplate, not a flywheel. 2 totally different things.

 

uh..... have you seen the flywheel on a auto? hehe...it's really really light compare to 5 speed... hehe... why change it?
