okay guys... been doing tons of research and here's my dilema... got an '02 5.4 n/a bone stock (reg cab, flare side, 2wd), went to put in a transgo shift kit (not cool!!! dont try it! research 1st. tons of posts from old ford engineers on how bad that is for a 4r70w!!! increase line pressure w/ a chip!!!) wouldnt work. at first, was stuck in 2nd all the time. after going back to a stock valve body i bought off ebay, it will ONLY go into reverse. worked for a test drive through all 4 up and down then tried to test passing gear downshift, thud... driving back to the crib backwards!!!! still sitting... boo hoo. perfect fluid level, filled w/ mercon V, so no, not fluid, no leaks...

now... i am sooo sick of this trans, i was pondering swaping a 5 speed manual out of a GT mustang. i know i can get that gear box to bolt up, i can fab up a trans mount, and get a shaft made. the brakes are one thing in question, the position of the shift linkage is another. i know the vaccum booster wont work so hot on the manual. ive done these swaps on older carburated vehicles, but something this new.... i was hoping to find someone that has done it b4, hopefully w/ mostly bone yard parts, and some fabbing. best thing i could find was a guy who put the 5.4 in a stang gt (02 or 03 i think). god i want that trans in my Boss5.4... it would live up to its name a little more... ati procharger is next, so getting the brakes to work right, and the check eng light to stay off is a must for me... think i can do it? any feedback? please help!!! stay tuned...

 

maybe a zf instead?

 

Look what JMC has for an M5OD, and go down to the pre97 section and look what PJF has for a mustang tranny.

The distance from the edge of the bellhousing, where it bolts to the engine, to the center of the shifter is about 18 inches on the 00+ M5OD. The Stock T-56 is about 26. The shift lever on the T-56 can be relocated closer to the bell housing but I am not sure by how much so you will have to check. Check out the available gear ratios too. I think the best you can do is 2.99 1st on the T-56. The M5OD has a 3.9 1st. You could just get an M5OD but you will end up breaking it. A ZF is taller than an M5OD so it might hit in the transmission tunnel. Never easy....

yeah, but finding a t56 out of a cobra is a little harder than the m5od out of a GT... what trans did you throw in JMC? i thought i read on here somewhere that you ate up a pair of m5's... that and did you do anything to your brakes? are you using the stock vaccum setup?

 

I am still breaking the M5OD's. This is the third one that I have installed. I am saving up for a ZF S6-650. The T-56 is readily available from aftermarket suppliers. Call these guys. http://www.ddperformance.com/ I don't understand your question about the vacuum for the brakes.

You could try a TKO 500 or TKO 600... I am sure you could get it to work with a uniiversal bellhousing... it would be a lot $$$ though.

 

You would be better off with the TKO. It has a lower 1st gear, 3.27:1 that the T56. You can also get it with the 4.6/5.4 bellhousing. There is a mid or forward mount for the shifter. This moves the shifter 6 or 12 inches closer to the bellhousing.

A guy did a T56 swap on fordtruck world. He had lots of posts about it under "transmissions" in the forums, but I couldn't find them very easily. I remember it being a 6 speed from a mustang cobra and it costing a fortune. Also, the tranny length came very close to the seat, but did work. Here's a link to his photo album. Good Luck if you decied to do it.

Great posts guys! that really helps. JMC, i was just wondering if you did anything at all to the brake system besides maybe a little pedal re-working. i was looking at my buddies GT mustang, and its brake booster is powered by the PS pump vs a vaccum booster on our 150's. i am going to look for a t56 locally. see if i can find one. my truck isnt a hauler, or a mudder, more of a street truck than anything. i do plan on throwing on a Scharger, so i need some extra strength. i was trying to keep it somewhat cheap, so a custom bellhousing and a gearbox for 2 grand is a little much. but since my truck is immobile, i can justify it a little more

 

There was no need to touch any of the brake system on my truck. It came with a manual tranny and a 4.6. I swapped the 4.6 for a 5.4.

okay, so it should be just a simple pedal swap on the interior, and making sure i have clearance for the shifter... i can always fab up a shifter w/ proper bends to make it comfortable, no biggy. the t56 is pricey, and the m5 is junk... anyone ever try it w/ the tr3650 out of the late model stang? i wonder what kind of beating it can withstand... my buddy pounds on the gear box in his '02 gt, which is why i was even considering.

 

I've emailed Ford about this very subject. They should offer all 4.6 and 5.4 litres in a manual trannie. They only gave me the sorry to hear you aren't pleased email. You all should flood them with emails, and maybe they'll listen. we need manual trannies!!!

 

i know right...

 

okay, so it looks like i am going with the tr3650 out of an 02 or newer 4.6 stang. should bolt up, flywheel should be easy and clutch too. ford rates that gearbox at 360 ft/lbs tqu, and its in the new gt which makes 300hp/320ftlbs.... w/ 3v 4.6 stock... my 2v 5.4 doesnt push that, added wieght is a stress factor of course, but what i dont understand is how you can throw an Scharger at that 4.6 and the tranny still holds (under normal street use). does ford under-rate these torque specs? another question ive been researching is the speedo... looks like the sensor for it is located w/ the abs, on the wheels somewhere, and the stang is the same. i am used to a cable and a gear in the trans. is this true? is it as simple as configuring the ecm? or am i way off here?
