NEED HELP ASAP!! Cars dead!!! Tranny problem

[randkcustoms]

Ok, I have a 06 SRT, I just did a cam swap and headers. I have drivein the car around some maybe 25 miles. Runs great! no leakes nonthing, I took the car to the sound shop to have a full system put in and drove the car home, and ran great, next day took the car out to have the system tuned more, and it drives fine no nose nonthing, then out of no were, the car just stops driving, no power to the wheels, fills like some on put the tranny in N, dident make any sounds, or nonthing jerked, no leaks still. We coast off the road put it in park, and it starts to roll back, make sure its in park and it is but is rolling back no nose no clicking when its doing that, so I put the e-brake on. car is ideling just fine but the dash is light up with everything. So I pull the codes, the only code I have is IAT but thats always been there. No tranny codes nonthing. Then I put it in Drive and give it gas and nonthing, the RPMS are cut down to like 1500 or so. Put the car in Reverse and nonthing. Car revs up just fine. So I reset the addaptives on the programer reinstall the tune, no help. So I pull fuse 16,14, and 11. Whats crazy is when I looked at fuse 11, it wasent in the 11 spot, it was moved to 12. So I dont know how the car even started with out it......but I moved it back and still no good. So now the next thing im going to look at is there is a transmission fuse in the back of the car, Fuse, 37. Not sure what it dose. I wouldent think the tranny would of been tost. So im looking out to you guys now to see what I can check, do????? Please help!!! the car is in the parking lot.

[sundin13]

the fact there is no viable code tells me to lean toward checking more fuses use the meter and check alll fuses for continuity thats the first step

bad ground from the sound system job?
overload of a circuit?

who knows..

thats really weird.

what about the pink tab thingy on the shifter?

[randkcustoms]

That pink tap thing is my guess to. Havent looked at it yet. We checked the grounds and everything. it drove fine all day then the next day is when it happend. Im running just almost open headers right now so maybe it got to hot and burned a wire on the tranny maybe??

[dudeiwin86]

.....yea

do you even have the midpipes on?!?

[randkcustoms]

No, I just have straight headers with some pipe welded on for now. But all the wireing looks good on the tranny, I grabed the drive shaft and in park I can turn out but then it clicked like it locked in so I thaught I got it, but still nonthing.

Halfshaft

[randkcustoms]

Nope they are fine. How could it be that when there is no park?

[GasGunR]

Because you have an open rearend. Jack up the rear and check.

[dudeiwin86]

one way to check would be to jack up the back end,
and put it in gear.

dont rev it up, you dont want to free spin it too quickly or you can cause damaage,

but you need to see if the tranny is engaging the drive shaft,
and if the drive shaft is engaging the rear diff/axles.

one way to check the axles/diff is to jack up the rear and spin the tires by hand. it should turn the drive shaft.

if the drive shaft engages the tranny, and spins, this eliminates it as the problem, and vice versa

[randkcustoms]

Ok I will check that. so when I towed it home wouldent it make some nose?

[GasGunR]

You would think it would... but if the driveshaft locks when its in park, but the car still moves, that leaves a break in the driveshaft farther back, the ring and pinion, or a halfshaft. Since halfshafts break around here every other second, that's my guess.

[dudeiwin86]

usually you should hear those things break..
go get you car jacked up and twist those thigns and twist it all around and make sure its all connected up and working in harmony.

if anything you want to inspect and eliminate (or diagnose) those areas as problems

[randkcustoms]

Yeah. I will report back when I try that. Could it be a bad TCM?

[randkcustoms]

And Also, how are dealerships for warrenty stuff? The car is modded big time, its just headers right now with really no exhaust. So they should still fix it since the exhaust is not the problem right?? Im thinking about having it towed there. but I want to have my ammo ready
