Removing 22mm crank pulley bolt on Automatic

Okay.. I've searched and searched, and have only found information on how to do this with a 5-speed (put in 5th gear, step on brake... blah blah)

I have an automatic, and am tring to take my crank pulley off so I can install my new Perrin pulley. I went and got new bets and took everything apart. Now it's sitting there... dissassembled... with the old pulley still on.

I tried using a belt and vise-grips with various methods, all to no avail.
Does anyone else have any ideas or secrets they're holding back? Possibly using the 4 small holes in the pulley body?
I'm in a bind, as most people have 5-speeds and use a different method.

Because there is no 'Automatic Transmission' forum, I decided to post this here. If any moderator feels this would get more views/responses or belongs elsewhere- please move this thread.

Thank you for any input. I'm without a running car until I get this FARKIN bolt off!

There's a small cover on the bellhousing on the top passenger side that you can take off, once you take that off you can shove a pry bar into the hole and rotate the crank bolt (with a 22mm socket on a breaker bar) until the pry bar gets jammed, them pull harder and it will come right off, install is the reverse.
Cheers,

Here's how I did it on a '00 RS:

Remove fans from radiator
Slip socket over crank bolt
Slip a 3' pipe over the breaker bar
Disconnect all the spark plug wires
Have someone hold the pipe, leaning up against a piece of wood on the fender lip
Tap the starter - and I mean TAP!!!!! - just for a millisecond or two
Repeat until starter breaks the bolt for you
Remove bolt.

Personally I use air tools now, but that requires removing the radiator in your case.

Good luck - use proper safety gear and lots of uncommon sense!

I usually use those 4 holes on the pulley. You can make your own but it'd probably be not worth it. You'll need a thick metal plate and 4 bolts that fit through the holes a little less than snug and bolt them securely. ANd then you'll need to drill a hole in middle of all the bolt area in order to fit the 22mm socket in.

I had top take the fans off and used a large breaker bar and chain wrench worked like a charm.

Don't do it! Crank pulley = worst modification ever. Seriously, it caused me nothing but problems!! (Including squeeky belts all the damn time, and a leaking water pump!!!). Worst mod I've ever done... by far! I took that POS off and sold it for like $25.

You may say its the worst mod, but so far, It's been the best bang-for-buck power mod I've done (on my lame *** N/A 2.2).
I guess to each his own... but I've only heard of good results from lightweight pullies (not underdriven)
