AOD, NOS and Toploader
- Thread starter tinfixer
- Start date
AOD= automatic over drive (later model 4 speed automatic)
NOS= either NEW OLD STOCK ( which means a replacement part that is identical to the old one, not some piece of crap chinese part) OR Nitrous Oxide ( a chemical power adder for the motor)
Toploader= old manual transmission often used in Fords, can be good tranny, but you should know what you are buying if you are going to put one in your car.

NOS isnt nitrous oxide, its a brand who makes NO2 systems.NOS is in the mustang world usually new old stock. (new parts but "old") A toploader is a ford 4 speed with a cover on top (it "loads" the guts from the top). Toploaders are the best trannies. They are friggin bullet proof and come in close and wide ratio. Theres also big block toploaders and stuff.
Well if we are going to argue...
Toploaders are good transmissions... Best would be a Tremec 6 speed or something along those lines. Still damn tough and with 6 gears. Even then, someone might say an automatic is better. About the best you can get away with saying is that it was the best manual transmission that came in a stock classic mustang.
NOS in terms of nitrous oxide does stand for "Nitrous Oxide Systems" and is a brand name...BUT ever since those damn Fast and Furious movies, alot of people use the term when talking about Nitrous Oxide and NOT the brand name. Sorta like calling a personal watercraft a "JetSki"

. That whole NOS thing just bugs the crap out of me. And I am sure he meant N.O.S in the question anyways

I think what Mitch was saying is that you make sure you're not buying a 3+1 Toploader, which is a 3 speed Toploader with overdrive.
There are big input/output Toploader 4-speed and small input/output Toploader 4-speeds. There are also 3-speed Toploaders. I think the 3+1 is the 4th and final version. You also have short and long tailshaft versions and even then there are tailshafts that have mounting bosses in different locations. The Jerico transmissions used in NASCAR are based of the Toploader design, and even then, there are circle track Jericos and drag race Jericos.

I'm just trying to ed-ju-ma-kate tinfixer. He may or may not already know this, but some others that read this may or may not know as well. BTW, the 3-speed that came out of my '65 ended up in a dirt modified at our local track. I understand that the toploader 3-speed was sort of desirable, at least locally as the gearing worked out well for the track. Stories of them ending up behind shivveys on the track as well.
