Does anyone know how many teeth are on a stock AOD flexplate? Thanks, John

157.

I believe a 1989 AOD uses a 164-tooth flexplate (50 oz balance / 10.5" bolt circle).

The C4 uses the 157-tooth flexplate.

Unless you have the big bellhousing for the c-4 you cant use aod flexplate. Take the 154 flex plate and the aod flexplate to a balance shop. Get the c-4 flexplate balanced to the aod fexplate specs. Just went through this a couple of wks ago. 40-60 bucks should set you free. Make sure you dont have a c-5 bellhousing (big) as it is deeper than c-4 and convertor will not work. dunno if this is your prob. but some things to keep in mind

Oh I decided to go with an AOD and not the C4 tranny, thanks anyway though. John

I don't have one handy for counting, but according to "The Official Ford Mustang 5.0 Technical Reference and Performance Handbook", page 346, the AOD uses a 157 tooth flexplate.

Take care,

Hey Chris, what do you think of that book? I was thinking about picking one up, just haven't done it yet.

PKRWUD · 12-08-2001, 07:58 AM

It's excellent for factory specs and numbers! I just picked it up about 2 months ago, and have found it very convenient when in need of cam specs, vehicle weights, etc. Best of all, it's an official Ford publication. I highly recommend it.

Take care,
-Chris

Cool! I think that would make a good Christmas gift.

PKRWUD · 12-08-2001, 12:45 PM

Why, thank you, but I already have a copy.

Take care,

I have an AOD and C6 BB. flex plates. I did not count the teeth but they match up, so i would think they are both 164.
