MAGNA's AOD Buildup

yea hd there are red or blue clutch packs

[Archangel]

Red Eagle (or something like that) clutches, usually mentioned in combination with Kolene steels, look in Oregon Performance Transmissions's ebay store for them, they used to carry them last time I checked.

you also have Alto Red

[Archangel]

maybe that was it then, which ones are the better, Alto or Eagle?

No Kevlar whatever you pick. They don't have great friction properties and will need a whole lot more clamping force to grab. Usually you'll see overdrive bands made from that. It holds up to heat well, but it will have a bit of a slip to it. It makes a decent choice in a track only trans but for street driven stuff, its not so great. The slipping generates a lot of heat which isn't good for the rest of the trans.

What's in store for a valvebody? Not being a tranny expert, I don't know how much they really affect durability, but I was quite impressed with the one in TL's car even though I didn't go for his claimed very firm Third-to-Fourth shift at WOT at around 130mph.

Super-scary thing is, after doing some seat time in my mother-in-law's car, I'm getting friendlier with the idea of a stickshift tranny in the future ..... :p

thank you. *breathes*

I just got the stock valve body...going to have a Shift Kit in it tho....why? is there a reason I should get a new valve body or something?

Well, dunno, steel valves in aluminum bores, can make for some funky shift action.

Didn't Art Carr make a full manual valve body for the AODs tho? Or was it Lentech? In any ways that would be fun to drive, faster shifts than a manual and no clutch pedal to deal with

Having thrown away a couple dozen of them due to galled valve bores, yes, either buy Performance Automatic's AOD valve body at around $190 from Summit or Jegs (I can't remember who has them, or just buy them direct from PA), or the Street Terminator from LenTech....at around $430 shipped from Canada.
Having used both?
LenTech kicks ass, they are built for the vehicle, whereas the PA VB is simply a shelf unit, one-size-fits-all.

[Mr. Land Yacht]

ok..so a new valve body would help out...ok..maybe I should get one.

so something like this?

can someone explain to me what a Trans-Brake is? I've heard of it before...

[Pirate]

It is an electronic valve, via the valve body, which activates both the reverse and forward clutch packs, locking the car in place.

Yep, that's it.

[Mr. Land Yacht]

oh..that's interesting....thanx for clearing that up mang.

ok...maybe I'll get it...for 200bux, can't hurt....proly save my trans mang a little time in the buildup.

[DuceAnAHalf]

a trans brake is used in drag racing to reach the full stall of the converter.

say your converter is rated at a 3000 stall, well with the foot brake you may only be able to launch at 2600. If you have a trans brake it locks the transmission so you can bring the motor to the full stall at 3000 and launch there.

pretty much every turbo'd automatic car uses a t-brake to build boost before launch

Do those Performance Automatic valvebodies come ready to install, or do you have to reuse your old pistons and stuff?
