Hey all,

Has anyone out there done a torqueshift to a six speed manual swap? I think I'm going to give it a whirl sometime in the near future.

firewall tunnel was raised to accomodate the ZF. You'd have to change the carpet and sawzall the tunnel section from a donor, and splice it in. Bell housing and t-case bolt up unless you source the ZF from a 7.3 which has smaller trans shafts (at least on the auto). necessary speed sensors should be similar, but idk. I belive it's a separate harness, so no problem. you may need different length drivelines, but a quick measurement of total trans length would give you the answer. my buddy has a '99 6 spd zf with 65K for sale for a good price in Idaho if you're interested.

 

So your saying the entire cab is different between a auto truck and a six spd truck? I find that VERY hard to believe.

 

I've got both at my shop right now, and I'm looking at them. clearly the tunnel is different, but just the front of the tunnel & carpet, of course.I'm positive. about 4" from the front firewall sheet metal, right after the air bag module(the computer covered by the black plastic peice below the dash in the middle), the auto floorpan drops quickly, leveling out all the way back. the manual floorpan slopes gradually after the airbag module until the front of the seat. I looked into it carefully before I dumped a few G's into my torqshift, and built my crew cab. I also had an '02 stroker with the 6 speed. It's only the middle of the tunnel. It shouldn't be too complicated to cut out that section, and screw & glue a new tunnel section on in place of that. I'd say it's easier to convert to a manual (as far as the floor goes) than the other way around though.

 

Ill take your word, as ive followed your posts and you have way more experience with this then I do. I just never would have guessed in a million years that they would have been different.

 

I would have never guessed the tunnels were different. No problem, it should be fun. Thanks for the heads up.

 

i have a 05 that im looking to do the same swap. does the trans have its own tcm? would i need a pcm from a 6sp? i would like to get as much info as possible on the electronics. thanks in advance.

 

The only thing you really need to worry about on the '05 is cruise control wiring, & backup lights. the auto has a large wiring harness that goes to the pcm/tcm, the manual has no harness that goes there. You need to setup the clutch pedal to kick of the cruise, just like the brake does, & wire in the backup lights with a harness you might be able to get with the transmission. I'm told the 7.3 has it's own bell housing, so don't source your trans from one of those. I believe the 6.0 has the same bell housing as the v10 & 5.4L V8 though.

 

You were told correctly. The 7.3L bellhousing will not bolt to a 6.0L. The 6.0L shares it's bolt pattern with the 6.8L and 5.4L.

 

Thanks for the confirmation

it changed my mind on doin the swap. not actually that difficult. the trans hump is different but you can either cut it out or get one from a manual. all the rest is in the forum.

 

So im new hear an i just bought me a 2003 6.0L, im getting the EGR deleted an headstuds done ASAP! but im curious about transmissions...what kinda tune can the 5r110 hold stock? i have herd of the 6.4L 5R110s can hold a spartan 275 tune an a 310 tune with an aftermarket torque converter? so would the 03 version hold up to the same? or should i spend my money an swap a ZF6 into my truck instead of screwin around with an automatic? whats ur guys oppinion?

 

the r5110 can hold a pretty decent amount of torque. its all a matter of opinion whether you like standard better. i like it better and the swap was not that painful. one thing i found, make sure you get all the necessary pieces beforehand. i forgot to swap the engine-tranny spacer plate and ended up not being able to bolt the trans to the crossmember. last thing, the zf6 (s6-650) has two versions, standard torque and high torque. either one will be plenty strong, just dont shift too fast, youll bend a shift fork like i did!

 

No, the 03 version of the TS would not be able to handle a Spartan tune of that magnitude and even if it did the headbolts sure wouldn't. However, I know first hand that the TS won't be able to handle it, because I have 508 horses going to my TS and I had to have it rebuilt stronger about a yr after doing those mods. Still it lasting a year is a testament to how well that auto tranny is.

The autos on this trucks are far better then say the auto on a 6.9 or even the more recent(compared to the 6.9 that is) 7.3s. I've been stranded by the 7.3 auto. It was/is crap in stock form, the TS isn't. Now don't get hack performance programming either, because that'll wreck havoc on the TS and that won't be cheap.

As to whether or not to do the swap from auto to man. that just depends on how much you like the man. over the auto. I don't like it one bit. Too much hand movement for zero satisfaction in my case. However, it might be different for you and what you want to spend. Only you can answer that question.

 

I have a 6.0 5R110 transmission (125000 miles) and pulled the engine and put it into a truck with a ZF6 transmission (257000 miles). The truck used to have a lot of boost, but now the boost doesn't kick in until about 1800 RPM. I'm assuming Ford has the PCM programmed to limit boost when it has the ZF6 transmission.

Does anyone know if this is true?
