I want to rebuild my AOD. What is the best rebuild kit on a budget? I have read on some threads that a good rebuild kit would consist of Borg warner clutches and raybestos steels. I also want to replace the overdrive band. I also found out that a standard friction OD band would be better than a Kevlar OD band. Any comments or suggestions?

when I had my car I just told my tranny builder that I needed something to last under the abuse I was dishing out..especially after my 3.73's went in.
What he built was perfect :) He races both of his fox's (one stick one AOD) so I trusted his judgement :)

I suggest Borg Warner kit, new steels, Kevlar band, A/A+ OD servo, shift kit....that is about the BAR MIN, any less is a waste of time.

Lets not forget bearings and bushings if yours are ate up....

yes that is a good price and get performance clutches....so they say. Some trans builders will argue.....Alan being one of them, and now me.

Why?

Alto kevlars are NOT in good respect with some builders I know due to quality issues. Especially the ALTO DIRRECT PACK........any good AOD/E/4R builder knows that thinner steels are not how you acceive better performance or reliability. So due to the fact that they still advertise this info and the use of kevlar clutches, not good.

I would suggest the use of BorgWarner, Raybestose High energy, Indy Reds, or even blues before using kevlars.

Kevlars have PROVEN themselves to be rather slippy under high torque applications, errosive to steel plates, and were designed for LOW WET conditions in the first place with the abbility to absorbe alot of heat without breaking down as quick as paper or other compounds. Also let me add that they are NOT GROOVED and proove to have slower application speed than sticky grooved paper cluthes.

If you do choose this kit.....don't use the thin dirrect steels....deffinetly not a good idea....I have seen many self destruct due to warpage.

I was told that a standard friction OD band is better than a Kevlar OD band because the kevlar band is too hard and cause slippage. Is that true?
they can also wear the reverse drum prematurely, and if you have upgraded to a mech diode, who wants to have to replace those all the time?



anyhoo, for me, im going stamped steel aode direct drum, and ill be using oe bw direct clutches and not the power pack........along with a manual vb, 4r planet, and the rest of the 4r geartrain.

That makes for a pretty tough AOD matt....good luck.

As for kevlar bands...this is my take on it.
Kevlar bands are tough, and don't wear out near as easy as paper. NO I don't use them in the 2" conversion, however I do use the 1.5" band on the roller diode if my customer doesn't wish to upgrade. WHY, cause it has far less likelyhood of going bad as quick. If it ruins the drum, oh well, they are cheap....and they should of upgraded in the first place :)

Where would I be able to buy the stock standard friction 1.5" OD band? What do I need if I want to upgrade from the stock 1.5" OD band to a 2" OD band? Where will I be able to find a shift kit with borg warner clutches and new steels? I would also like to upgrade to an "A servo" or "A+ servo". Information greatly appreciated. Thanks!

All that stuff can be found at bulkpart.com...it is a great site for beginers.

You will have to buy a trans kit, band, filter, shift kit, servo seperate....all that stuff doesn't come in a kit from them...you kinda gotta know what you want. But it is all there.

As for 2" band - that is 4R70W transmission stuff, and bulkpart has a section for that trans as well. However, to install the 2" band in the AOD, it requires the use of the AODE/4R70W reverse drum and AODE stampe steel 4 1/8", 36 tooth sun gear shell to use with the AOD gear train.

I buy my kits from Transtar because they are local, but you can get them as cheap through Northern Auto...

Some good advice here; I'd suggest getting the ATSG manual, along with an appropriate Helm's and even the Hayne's Ford Transmission book. Too much info is not a bad thing, LOL!

I have half a write-up done, if you want to take a peek, and about 300 photos, LOL!
