Lightweight crank pulley on an AUTOMATIC
 

Has anyone done this already? will i run into problems such as smoking out the torque converter, just bought a perrin one and im a bit uneasy if this will break things. also whats the name of the tool to hold the pulley in place for this motor? thanks guys

Yep I've been running a Perrin pulls for over a year with no issues. I don't think there should be any concern about you're torque converter. It makes a difference, but not that kind of difference.

When i presented the idea of buying one for an automatic i was told that it wouldn't make a difference whatsoever so i'd be wasting my money

How would it have no difference? The fact that you are reducing the rotational mass would definitely make a difference.

The real question is how much of a difference. In which, others can chime in on their experiences.

Have the Go Fast Bits pulleys set installed on AT. No issues so far, although no considerable difference either. I mean there is difference, the engine feels a bit "lighter" and responsive to the acceleration pedal, but far from "day and night" improvement.

To remove the stock pulley you ideally need something like this:

But in fact what is required is a metal rod with 2 "fingers"/bolts which could be inserted simultaneusly into any 2 of the 4 holes on the stock crank pulley to hold in place while unscrewing the bolt.

I have about 15000 miles on a Perrin Lightweight pulley with no issues. No night and day difference but the engine did feel a touch more responsive. Taking away rotational mass can't really hurt... can it?

haters gonna hate

That makes absolutely no sense whatsoever. Not chastising you, more just indicating somebody gave you bad info. Losing rotational mass on any car is good, including automatic transmission cars. Do lighter wheels help AT cars? Do lighter drive shafts help AT cars? Do light weight parts in general help AT cars? These are rhetorical questions, the answer to all of these questions is "yes".

And for those comparing, this won't make a night and day difference on either an auto or a manual. It will make a slight difference in responsiveness as people have indicated (I've run pulleys on past MT cars). This for either an auto or manual. For the cost, I do consider pulleys a worthy mod for either an auto or manual.

ive heard thing about the torque converter smoking out due to way too much weight being taken off. i just wanted to see the peoples experience with the aftermarket pulley on their AT cars. also will it throw off the check engine light and how did you guys who have it on your car get it on in the first place?

Your answer reminds me of this guy:

A crank pully tool is needed to install in on an AT which basically just allows you to hold the pully still while while allowing access to the bolt. I got the one from Grimmspeed. I've been running my peering pulley for over a year now and have had zero problems with it.

Can anyone show me how to install it?

Just check out the DIY. It's exactly the same as the MT except you need a tool to hold the pulley still while you loosen/tighten the bolt.

Should have gotten a manual?
