Basically I need a new transmission according to the experts.

My 97 last week went from quick firm 1-2 shifts to super soft Cadillac like spongy shifts, instantly this caught my attention. I pulled over checked all of my gauges and fluids and nothing was out of place, temps normal, oil pressure normal, volts normal, no dtcs, no OD light, hmmm weird. I revved the car up lightly in park up to 3,000 to verify my IMRC's were operating correctly, sure enough they were, msd box getting proper revs per display (had a problem a few days before with rpm fall out). During the rev though I noticed a weird sound on settling almost like valve clatter but not rev consistent...weird... I revved it up again and heard a loud whining coming from the transmission area. Like magically I had a vortec supercharger under the hood pssh I wish. Then I heard the rattling sound again on de-rev. It sounds like a coffee can full of marbles.

Alan (DirtyDog) tells me it is likely that my roller clutch is letting go and that the whine is the snap ring rubbing against the case and the marble rattle sound is the rollers falling out. :(

(I trust his opinion and diagnostic and will be buying my rebuild parts from him)

My future uncle (in-law) says that Alan is full of **** (doubt it) and that it's probably a sub-par performance torque converter letting go [causing soft 1-2 shifts] and the planets are letting go due to fragments from the tc working through the transmission [hence the whine]

(I don't believe him at all and only listened to his rambling because my fiancé called him while I was in the shower and told him about the transmission problem. I have access to his shop at my disposal, even though I won't use it because that would require tolerating him and his less then accurate opinions.)

From what I understand anything 98+ has a mechanical diode assembly installed from the factory. Alan had suggested a 03+ if I remember correctly but said that the 03+ would require a tailshaft swap as well as re-pin.

My current setup is:
4.6 Dohc with mods
Lasota tune from Don
97 transmission
DirtyDog torque converter F63HSHD (I think)
Jmod by Supergordo
Castrol Mercon V
LPW finned deep sump aluminum transmission pan
And other misc supporting mods.

Basically I wanted to know what year 4r70w transmissions I should be looking for ideally, like I said I'm not certain that was the correct year that Alan told me over the phone it's been about a week since I talked to him last and my memory isn't the best.

Regardless of what year I buy I'd like to go all out with this transmission (within reason) so it will be getting a complete rebuild.

So far on my list I've got:
98+ good core
Rebuild kit from Alan
Forced lube rear bushing mod

I wanted to know how many plates should I go with on the forward drum?
5, 6, 7, wave? No wave?
What difference does that make during the build? Sorry for my ignorance.

Should I upgrade the stub shaft?
Should I upgrade the sun gear?

Is it possible to reuse some of my 2,000 mile jmod parts from my car now or is it all crap now?

Is my TC able to be reused or is it a paper weight now?

Thanks for you help anyone and everyone.

Also what years should I avoid at all costs?

I have a tired 93 trans sitting in the corner of my garage that I was told to use as a paper weight or emergency for my 95 bird.

My buddy found me a Local "shop" that sells any year 4r70w for $700 to my door cash on delivery completely rebuilt with a two year unlimited mileage warranty, but that seems too good to be true.

04 mustang transmission with your planet outer ring gear, OSS sensor, extension housing, output shaft with solid sealing rings installed, spiral snap ring on intermediate one-way and a high energy band. That is a good base level transmission. Beyond that mod the valvebody install the sonnax pr valve kit, make sure the epc is new and install the sonnax overdrive servo pin. I would also add a few clutches but that is getting more involved.

Out of sheer curiosity is a 01,02,03 worth swapping in? Not trying to beat a dead horse here, I'm just not having much luck finding an affordable 04 locally.

Well it's officially :znanner: time! I got my 2004 mustang transmission today. Tag number 3R3P-7000-BA. Seems to match what this post says. http://forums.tccoa.com/showpost.php?p=1332185&postcount=13 All for the wonderfully low mileage of 16,000 and low low price of $350. Let the tear down begin.

Right on :D are you going to throw your customized J-modded valve body in this one? Are you going to replace your trans cooler? I am just thinking about the idea that you want to avoid sucking up any metal shavings or other garbage that the dying trans may have introdued to the system somewhere before / after the trans / in the lines. Anything else going on with the car or is it just a new trans? That's a hell of a deal, BTW ;) I've got a single piece 93 Mark VIII driveshaft coming for my bird this week...going to get it balanced & new U joints pressed in, then it's on to a new computer tune

I know. I've been shopping for them for weeks, I was shocked when I asked this guy what his lowest price would be I jumped on it right away before someone else got to it.

I'm probably going to bypass the radiator entirely and use a stand alone 45,000gvw cooler possibly with a fan. If not I'll flush the lines and cooler with that cooler kleen stuff. The TC is getting pulled and shipped to Alan for decontamination and possibly rebuilding with a new lining depending on the extent of the contamination. Hopefully it's not wrecked.

That gold nugget you found is WAY too good for Rad Cooler - Do it right - They are a dime a dozen on Ebay.

I've been on the fence for a while on whether or not to completely bypass the factory cooler, but from my understanding even in my brutal 115+ climate the 45,000gvw cooler will be sufficient. ;)

Delete takes heat load OFF the Rad too so that;s ALL good - Toasty her in SC & all I'm running is Aerostar Tranny Cooler - 11 inch DD TC could throw a tad more heat load but zero probs - What you see is slower Temp Rise on Gauge & fewer fan cycles in normal operation.

So basically since it has such low milage should I just order the 98+T11 and 76833E?
Should I get the 4R7911, 4R7111, or are they already hardened in the 04?
Can I reuse my pressure reg kit 769223 from my contaminated tranny?
Can I reuse my larger then stock overdrive servo?
Does the new pin work with the large servo? (I ask because the sonnax website instructions show the stock sized servo with the sleeve, my upgraded one is the larger unit without the sleeve)
In your jmod installation video I noticed you installed an aftermarket 2-3 accumulator piston with 4 o-rings, do you offer that as an upgradable option for the 98+T11 kit?

Thanks for all of your help Alan, the trans has those plastic plugs with bolts holding them in over holes the unused holes exactly where you said they would be. Will the second speed sensor hole near the mlps cause any interference with anything?

Sorry for all of the questions, I really appreciate you going above and beyond with your technical support for my swap. You have no idea how grateful I am. If your ever in Vegas I owe you a beer of your choice Sir. (with the exception of that insanely priced beer in a squirrel non-sense)

http://www.sonnax.com/ answers most of your questions.

Your new Main VB is WAY different so doubtful for PR swap - IMO what you have is a darn nice road tested JMOD''d Main VB for a friend.

Sonnax has new stuff for your 2004 VB.

2004 has 2.7 Servo already but maybe NOT the fancy o ringed Sonnax Pin - It's all swappable but you want new C Clips - Don't forget you can Pre Load the OD servo Spring per Sonnax if you desire,

I suggest the 76948-12k and the 76833e That is what I use on my builds. I do sell the piston seperately and include it in kits when needed. They are actually hard to find at times I ended up having to buy them direct from the manufacturer to get a fair price. They want me to order 2000 to get a great deal but I don't think I need that many....The speed sensor hole will not cause a problem I generally knock a freeze plug in the hole. I do not know anything about any beer in a squirrel I am a simple man Bud light will do just fine. As buck said the od servo in the 04 will be larger, use it!

BrewDog makes the beer, it's 55%, it's titled "End of History", and the bottle comes stuffed in a taxidermied squirrel. From what I've heard it's drank like a whisky due to it's strong alcohol content and it's cost is a staggering $750!



I'm glad your more of a budlight guy. I've got plenty of those in the fridge. Lol.

This is all kinds of wrong.
BTW, if you guys want any squirrels, I think I saw a couple near my office.
You can DIY your own "End of History Beer".

PS. I showed this to a friend of mine. Her comment was "gross -- it'd be like kissing a dead squirrel"

Definately 76833E, how about the kit, would the 98+T11 kit be sufficient or should I invest in the 4R7Z11?

Should I get the 4R7911, 4R7111, or are they already hardened in the 04?
?

Can I reuse my pressure reg kit 769223 from my contaminated tranny?
yes?

Can I reuse my larger then stock overdrive servo?
Yes, but it's the same as the 04 unit

Does the new pin work with the large servo? (I ask because the sonnax website instructions show the stock sized servo with the sleeve, my upgraded one is the larger unit without the sleeve)
Yes

769223 is the product code for the 76948-12k kit from Alan's website from my understanding it is for 96-current.

I suggest the 76948-12k and the 76833e That is what I use on my builds. I do sell the piston seperately and include it in kits when needed.

What's the price on the piston?

Thanks guys!
