...this is what you said... all i replaced was the valve body...i wanted the 1 2 3/4 shift@ 6500. ...Frank...
Frank - if you read just a bit farther: "The AOD family of transmissions are capable of handling up to 400 HP using stock parts and a good valve body kit. It takes after-market parts to withstand 600 HP." And how much did you have to pay for the valve body?
Don, only the AOD-E needs a computer and there are aftermarket controllers or shift kits that handle the computer part. The AOD doesn't have any computer controlled shifting but it does have a throttle pressure valve that is necessary.
So you guys may know me from my thread on the 84 Marquis and 89 Marqius 302's I bought, the 84 Motor basically only needs an intake , carb and front sump for switchover, the guy threw in the AOD, and it does work. My question how hard is this swap if I pull my c-4 and 250, then just put this 84 with AOD in my car, I have a column shifter right now with the c-4, I'm just asking becuase I too got the tranny for free, assuming it shifts fine what has to be done to bolt it up? Just trying to weigh what to do here, will it cost more to adapt this tranny to my car or to just get the C-4 beefed up?
...put your V8 motor mounts in and drop the motor/AOD in. bolt up the driveshaft....get one of my AOD crossmembers and you are set. ...:Handshake...
If the AOD is out of a Lincoln or Mercury full size car it will have the long shaft and tail housing. You will have to shorten the driveline. You will need new linkage. You will need to make sure the TV cable is in place and in good shape, as well as properly adjusted. I don't know what your skill level is but if you can rebuild the C4 it will probably cost more to do the swap than to beef up the C4. If the C4 is in good shape you could get by with just a TransGo 40-2 shift kit from Broader Performance. There may be less expensive places to buy the kit but you get the Broader technical help when you make a purchase. They have additional mods you might want to make. The shift kit can be put in without removing the transmission - all you need out of it is the valve body.
someone said that the 6 cyl. c4 won't hold up to a V8 something about needing heavy duty clutches or more clutches, different drums...also needs a shift kit. heavy duty oil cooler...V8 radiator. when you get through you still have a 3 speed... i went with the AOD for the...overdrive... i didn't have to change my ...driveline... c4...rebuild to handle V8 AOD...mods. to bolt it in and overdrive ...Frank...:Handshake
71gold, If the C4 is behind a 250 it usually has the same internal parts as the V-8 C4. You will need to install a shift kit to make it stronger if the engine is built. The cooler is needed to keep things cool with a modified engine. Both are necessary regardless of which transmission you use. This assumes that the C4 is a 71 or later. With the early C4 you need to replace internal parts with the stronger late parts. The amount of modifications to the C4 depend on the amount of HP that the engine produces. More HP needs more mods. The AODs come with two lengths of tail housings. The big Lincolns and Mercury cars use the long version and the Mustang and small cars use the short version. The short version will fit in place of the C4 in some situations. In most situations the AOD (which is 1 to 2 inches longer depending on model) will require a shorter driveline.
2 questions, 1st are you saying with a mild V-8 say 175 to 200 HP I don't need to really modify my '74 C-4? 2nd When you say "The short version will fit in place of the C4 in some situations. In most situations the AOD (which is 1 to 2 inches longer depending on model) will require a shorter driveline" Does that mean my Marquis AOD is too long, to use without major mods What you said here makes it sound like only the Mustang version would work and it would require shorter driveline.
How many miles are on the C4? check and see how long the AOD is...then check the C4... do a little math... shorting a drive shaft is not major ($40-$50) ...Frank...:Handshake
C-4 has only 72 k i just had a all the seals freshened as it sat for 10 years befor eI bought and sat some more while I had it, that tranny shifts like new!
