best stock trans to swap into the mark?

(Click here to view the original thread with full colors/images)

Posted by: AbrahamLincoln

ok im debating between a 5.4 truck tranny 4r70w, a 98 mark viii trans, or a mach 1 trans.

Also the marauder will swap in as well correct?

There are some local yards with good prices on all these trans with low miles so im assuming for these late model transmissions im going to have to repin the connector? I know thats true for the 98 correct, but is it the same for marauder/mach1?

ive heard of 99 stang gt trans' working. IIRC the tailshaft is different though...

maraurder and mach 1 trans wont work they are post 02.

Posted by: m_maker

03 Marauder/Mach 1 trans will work fine as long as the output shaft has the splines for the speedo sensor. The change happened very early in the 04. Suffice to say, it's the best trans you can get stock THAT will work in your car. If you plan on using stock TC, then make sure it comes with the trans. Although the 04 converters are better than 03, the 03 goes a long way ahead of older stuff.

yea do these newer trans have spots for my speedo cable gear? because arn't all the obd II stuff digital? is that what you guys are talking about the output shaft?

Ive heard that the mark viii trans are beefier than your run of the mill ford/ cars and trucks - that true? I mean the markviii was relatively expensive car!

anyone got a 5.4 liter F-150 truck trans in there Mark?

Ive heard that 99+ trans' use some type of magnetic speedo sensor. Im not sure if its the same with autos as I heard it about t45s.

Abe, go to www.car-parts.com search for the 98 mark 8 trans.
I got one with 20,000 miles for $275.00

Posted by: AbrahamLincoln

hey i did as well also! i found a bunch with low milage for under 300 bucks... the thing is, is that after reading jerrry w's documentation it was stated that the 5.4 truck 4r70w offers the most durability...

Also it says to go with the most modern 4r70w to go with as possible. There is a few guys around me that have put 2002 mustang gt v8's into their cars so im stuck between the three choices, or if i had the money i would def run for geno's, darrin or BOC built trans' but i just dont have the cash for that. I just want to get the best trans possible, which i would assume would be the latest model with the lowest miles vs the hassle.

The 98 requires repinning, i can handle that... But someone explained what is needed for the 2002 mustang and im assuming thats someting about a selenoid and changing the 7 tooth to 8 tooth?

im not sure what a 99+ 5.4 truck trans will require?

Posted by: AbrahamLincoln

hey im on tccoa.. and reading about the 4r trans, and that the cobras and 99+ newer mustang gt's use 8 bolt Torque Converter Bolt Pattern and the Mark 8 uses the smaller patter of 6 bolts?

So how in the world do you bolt a 2002 trans up to a mark 8 motor if it only has 6 bolts and its designed for 8?

i'm not trying to be an ass here but you can handle repinning a 98+ tranny but just the other night in another post weren't you asking everyone here where you are supposed to put the tranny fluid in, and also you were trying to check the fluid with the car off?? i dont think i would go anywhere near a transmission if i was you. pay someone to do it.

I too agree that opening up a transmission for ANY reason is going to be a bad move.

The 00+ transmission you are going to have to take BOTH your trans and the new one apart and put parts from your trans into the 00+ trans..
The speedometer pickup is different and you have to swap the output shaft driven gear.. again.. probably above your skill level at this point.

I know you want to get your car running, so dont make this more difficult than it needs to be.

"listen to the advice given to you"..
I know you are headstrong.. and all that, but in this case, your not gonna be doing yourself any favors..trust me sir.

I have 30+ years experience "doing my own work" on cars to fall back on when something "dumb" happens.

SERIOUSLY ABE...your not making 500+ HP, so you dont need the "BADDEST TRANSMISSION in the land"... having the baddest trans in the land WONT make your car any faster.

but so far ive switched up 02's, installed a window, installed a 150 shot wet kit in the mark, put in the walboro 255, new waterpump, new plugs, 160 degree T stat?

just because i didnt know how to doesn't mean I shouldn't "go near a trans", it makes me ignorant.. and now that I know - its pretty amusing. But i learned just like with all the other stuff. And if you have a problem with that I dont know what to tell you, but laugh it up because come hell or high water i like doing this stuff myself and learning. Since this stuff isn't innate, you had to learn it from somewhere! Jeez! tuff crowd. I pride myself on the stuff ive done myself... and i appreciate the help from here! So thanks!

But listen to those who have done it many times.
XLRVIII and jamie97lsc have had every bolt off that comes off of these cars.
Did you ever wonder why the trans is shot in the first place ?
Listen learn and do it, good luck just keep in mind what your geting into by those who have done it more then once.
No one here is pointing you in the wrong direction.

There is no dumb questions...but some questions show your lack of experience thats all.

I completely agree, in the short time he's had that car he's tackled alot of the things that many people are afraid to touch.. and as I said before "his confidence level is to be commended".

But.. at some point you really have to be honest with yourself about what you "can and cant handle".

I would be very leary of opening even the trans pan on an automatic, because of the express danger of contamination.

even a piece of LINT from a towel could end your entire project.

im cool with that... yea thats why i did take another look at the 98 - but what keeps me from saying forget the mustang 4r70w is that there are more around with less miles for about the same price range im willing to spend, and even if i go with the 98 i still have to do the same things as say if i went with a mustang.... Open up the pan, switch this switch that repin this etc

so the level of technical skill to do a mustang gt vs the mark is pretty much the same only in that yes the speedo will be off and yes i know my own technical skills and i would't attempt to swap the output shafts - thats where ide draw the line... so yea hes right i should just go with the 98 based on that reason but the updated trans and availabilty may make it worth it to take the two trans to a tranny shop and have them swapped for the same price of a 98 with low miles. ( plus added update of the newer valve body etc)

if some guys who run around with mustang trans could please chime in on how difficult more it could possibly be than the 98 ide be all ears! but as a matter of the speedo being off ? SPEEDCAL!

A very detailed account of what you're in for can be found here.

have faith :
i did this same swap 2 years ago,and i had never touched an automatic before in my life,

read all the articles,do the conversion and triple check your work,

i spent $400 on an 02 gt trans and the only other money i spent was for trans fluid, everything i needed was either in the old trans or the new,

no need to touch your exhaust manifolds ,you drop the exhaust after the cats.

i swapped my driveshaft out wheni did mine so i lower my fuel tank to do that,but i didnt remove it.

i dont want to tell this story and have someone incapable go and mess up and waste money,but honestly when i did it i was amazed how "relatively" easy it was doing in a driveway with no lift and no other person to even help,if i had a few extra things (like a smooth floor,lol,trans jack,air tools) it would have gone 25-30% easier yet.

Posted by: AbrahamLincoln

thanks for the vote of confidence, i going to grab up a late model mustang trans and go from there.... unless i find a deal on a 98 mark 8 trans i can't refuse

btw what is PKE-AD? I'm guessing thats the code on all 98 mark trannys but when i punch it in car-part.com they ask me for W/PKE-AD or With out pke-ad and im assuming that means that it has the original factory stamp on the trans to verify that im getting the correct 4r70w, correct?

Posted by: AbrahamLincoln

finally gripped up a trans, an 01 mustang gt unit with 46 thousand miles. I got the correct diagram for the repinning, that sounds straight forward.

It came with the torque converter, even though it looks a little rusty on the outside, im going to keep that torque converter in there. Should be better than my high milage unit i have in the mark.

got a speedcal so my 4.10s can be dialed in correct and makes the 8 tooth difference not matter.

Heres where im slightly confused and I can't get a definite answer through my research. I have a new MLPS and new TC selenoid (i know this selenoid has to be modified to be able to fit in) which im going to swap into the Mustang trans... but there is some debate on whether the manual lever/rooster comb has to come out of my mark trans and into the mustang one im swapping.

Posted by: Blenderhead

I'm not 100% sure on this, but I think the actual manual lever can stay with the trans, just you have to swap over the sensor so you have the same type that originally came with the car.

As for the torque converter, don't use the GT unit. The 2V motors have more low-end torque and not as much high end compared to the 4V ones, so anything with the 4V motor gets a higher stall torque converter than the 2V motors do. In fact people with the 2V motors will swap their TC out for one from a mark, marauder, or mach1 to get the higher stall speed. If you use the mustang GT converter, your car will be a dog off the line. If you aren't having any problems with the one in your car, re-use that. If that one is messing up, get another converter out of another mark, marauder, or mach1.

Posted by: AbrahamLincoln

Arn't the mustang and mark both 11.25? i read also they have the same K factor or whatever that means on tccoa

Posted by: kustomizingkid

K factor is another term for the stall.

the jerry w. write up on tccoa says that they have the same diameter and stall speed.... so i don't think thats the case.
http://www.tccoa.com/articles/tranny...on/page2.shtml

what you're saying makes sense though because the marks do rev higher than a mustang gt, i'm taking that into consideration... but go to the middle of this link and youll see the mark and mustang gt are both listed at the same inch and stall speed.

Posted by: Blenderhead

I never knew that. I always thought all the 2V 4.6s got the 12" converter. I guess as long as it is an 11" converter, feel free to use that one.

Posted by: AbrahamLincoln

well mustang 2v's get the 11 inch converter i dont know about other 4.6 2v's in various other models... but im happy that i can use it because it has way less miles than my mark
