Transmission Died

[Blaze86Vic]

LOL, hard to find? ROTFLMAO...

:stupid:

AOD is got to be the #1 most common tranny of all time. I mean it's identical in almost every aspect for a crap load of cars and trucks, and over a huge number of years. Now that I think about it, it has to be one of the longest running trannys without significant changes.

No kevlar. It slips and creates more heat. Wider band and heavier servo but no kevlar.

I'm not sure whether or not the Kevlar bands are good idea. I have heard people say to use them because they are heavier duty and others say not because of heat and slippage. Is it possible a trans cooling kit would help resolve any heat issue, and is the slippage damaging. What is the real benefit of using Kevlar bands? Also for the shift kit, I was told by a friend that you should not use one that puts blocker rings into the 2-3 accumulator to firm shifts because it creates a damaging shock load to the gear train parts. Any thoughts? Thanks

Yes, harder shift is damaging to an AOD, the planetary gears use aluminum bushings which can easily be damaged in a hard hitting shift.

Kevlar bands are good no matter what. They last longer and hold stronger.

I would recommend some nicer clutches to make a good long lasting tranny.
Alto Red Eagle clutches are one of the top names.

Talk to Scott.

Brian, his trans mang, is going to build my wide ration, and build Justin's. And justin's trans is fuckin' hardcore!!! :headbang:

Well, took the car in today to get the trans rebuilt and I'm very confident the work will be done well. I trust the guy as my brother was friends/worked with him. Also he works on Fords only, knows AOD very well, and has built trans for my dad's friends (mustangs and racecars). I talked with him about what I wanted and expected from the rebuild. I am getting wider bands and I decided I would go with Kevlar because I had a good experience with them in my old car. I am upgrading to the bigger servo, getting a Alto Red Eagle clutch, and a Transgo Shifkit. I am going to add a trans cooler myself after and that should be it. Also going to have the rear seal on the engine replaced while the trans is out because its old and leaks. Also, thanks Scott, talking to Brian helped me out a lot and helped me decide what upgrades to go for. I'll keep you all updated on the progress.

Good to hear you're getting it all fixed up.

Kevlar doesn't have good friction qualities. Yeah it lasts a really long time but it needs an awful lot more force to make it grab. a 2" OD band made out of whatever the "standard" material is with an A servo would be a better idea. No slippage problem, therefore less heat issues. The material might not hold up to slippage as well as kevlar does, but OTOH, it won't be slipping so that becomes mostly a non-issue. This article was written by a Ford transmission engineer. Have a look at the item at the top of the page. http://tccoa.com/articles/tranny/tra...on/page6.shtml

Actually this whole article has some goodies in it. Maily 4R70W aimed, but a lot of it applies to our AODs http://tccoa.com/articles/tranny/index.html#

Got the car back today and it felt really good from the 10 mins it took me to drive home. I saved the old gears to take pics, the guy said the trans was very screwed, but at least he could take the gears apart, unlike the ones from the AOD/E he was doing before mine. Will keep you posted and get some pics taken of the old gears, ect.

Cool. When transmissions go they seem to go in a really big way. I wish I'd gotten to see the remains of the guts from my truck trans. I know they were really bad.
