04 6r80 swap cobra

[03 Cobra DSG]

would you still recommend people to do this swap? Does the car feel faster than the 6 speed? I am curious how the 6R will do from a roll. Like if you loose top end compared to a stick car. Not sure if I still wnt to do this, or, do a T56 magnum. Then save up and get a used coyote 10 speed auto. Decisions lol

I would recommend the swap my car does feel faster till 3rd than its pretty much the same. I don’t think I have lost any top end pull. The trans is good till around 750-800hp stock and it’s pretty cheap to upgrade compared to other transmissions imo. I do drive my car on the street a lot so having the 6r80 is good in that aspect as well.

awesome bro. I think with these newer autos, the top end doesn't fall off I guess. do you have any videos of your car?

I got mine driving, Q6v2, OE 6R80 & TC, NA 4V w/cams. After an initial drive its better, I think the in gear brake on idle tuning needs some work due to the extra load on the motor from the auto trans in neutral and in drive. Hopefully will get to that this week.

My speedometer is not functioning. I have the Tan wire from the Q6 to PCM pin 84 green/white wire, its the OSS wire from the trans. Its set as 5v AC output. No capacitor since I have Q6 V2. Any tips?

Matt did you ever get it too idle with the extra "in gear" load?

Any one using the Coyote copperhead PCM to gain control on 6r80e transmission? also WB sensors, etc

This is the exact problem I am dealing with now. Idles fine until you put it in gear and it will cut off. Big cams, big blower and a Circle D converter. I am going to try a couple of things and maybe add an additional idle air control.

I have Kooks 1 7/8 LTs and it's a tight fit going in but it went. I had to angle it up and turn it some on a transmission jack. The next issue with LT's is that the shift linkage will hit the O2 sensor. It did with the Kooks headers anyway. We installed a junk O2 and got a socket on it. Heated the header around the O2 bung. Then we pulled down on the socket a little at a time until the linkage cleared the O2.

also can we clarify what to do with irs? someone mentions not to buy the ford racing driveshaft but im confused why i cant just put a sra pinion flange on my irs and use the driveshaft?

 

[98termiswap]

also no one has really talked about how to switch gears when using a 99-04 shifter or b&m shifter, im guessing its done with buttons what are you using for that?

 

[03 Cobra DSG]

Not sure exactly but I think the drive shafts are different lengths I’m using 11-14 Ford racing driveshaft I switched out yokes and am using an 03 cobra pinion flange. My car is SRA. As far as shifting I’m using a 99-04 stock shifter with a PBH shift lever and shifter stop bracket. Just put it in “D” and go. Or you can hook up one wire to your cruise control buttons and you can shift that way. Only other option is a Lokar sport shifter.

03 Cobra DSG, is the flange your using the circular one or the old school u bolt one?

Using 03 cobra pinion flange

 

[98sn95]

I'm not sure which one that is, I have a 98 gt and its circular in shape, as opposed to the older type with u bolts.

The 03/04 Cobra flange is the flat style that all Mustangs have, but its bigger than what's on your 98. I'd suggest swapping to it if you can.

 

[ShootyMCstabby]

• So left is the 03/04 cobra flange and right is the Ford racing 6R80 flange(which you can’t obviously use) I can sell you the 03/04 cobra flange if you want. Or you could get if off of someone else. Just letting you know.

The 03 Cobra pinion flange is used with 1350 u joints as opposed to the 1330 u joints found on the 94-04 Mustang GT’s and I believe V6 Mustangs. Upgrading and using the 03 Cobra pinion flange and u joints is definitely the way to go since they are stronger. Same thing I did when I went SRA.
