I've been having this crazy thought in back of my mind for quite a while already. Let's see what you guys have to say.
Titan/Armada/QX56 make almost 400 ft/lbs at low revs. Also Stillen offers a bolt-on roots blower for ll of them with no suggested tranny mods. This should put the torque output to near 500 (crank).
The gear ratios in the 5AT Z are identical to those in these trucks. What would not work about taking one, upgrading the VB and TQ and putting one into a Z? Or the tannies are same in the trucks as in our cars?

 

our tranny is the same as the q45 and m45,i also heard the titans is the same tranny.

 

New ideas are always interesting. Now --Im totally unknowlageable as to the design of the Titan series tranny, but things that have to be considered are bolt Pattern @ bell housing, length of trans---No prob there cuz u can have a shaft built starting with an aluminum Shaft ( The Carbon would have to hit the storeroom )Compatability of T/C to Flywheel---Location of shifter compared with stock Z--Under ideal conditions --Be best to have the two laying side by side and a little more info as to just what are the internal differences. Cross Member diffs are no big deal.

 

subscribing . to see if possible

 

They do use the same transmission in regards to the model number. I would expect the physical outer assembly to be identical in dimensions, but items such as the valve body design, torque converter and TCM programming should be radically different. Those truck transmissions are designed to haul a lot of weight at lower RPM and they taper off the torque pretty soon. I think the Titan redlines around 6000 RPM. So the way it would act and respond would be not conducive to a sports car.

Clutch packs and other aspects of the transmission should be identical between them and us. Offhand, I don't think there'd be anything to gain from a swap.

 

I dont know about that one, as the Titan trans i saw when it was in serivice was enormous and looked alot bigger then a 350Z AT, perhaps the bell housing difference but either way i dont think its a direct bolt on. The biggest thing i think you will have a probolem with is the torque converter of the titan is HUGE, which is probably why the bell housing large size. The trans physical internals might be same or similar but def not the bell housing or torque converter.

 

pragmatically, i think it would be cheaper to just do a tranny cooler , VB, and torque converter than to swap a whole tranny and stuff out?

 

That depends on how much of a direct bolt on it is. You could probably get a tranny out of a salvage Titan for a $1000 more or less. That would be much cheaper than a VB and torque converter. I don't know which would be better. I guess I'll be following this thread to find out.

 

I think he meant including the cost of modifications required to get that damn trans shoe horned in there. lol The trans maybe cheap but the custom work part isnt. I also wonder the stall speed differences between the 350z and titan, youre gonna want higher stall speed convterter for turbo apps.

 

If the clutchpacks are same everywhere and the TCM algorithm is different from the Z this swap would be worthless. Just trying to throw some ideas around. And the titan does redline at less then 5600, I believe. Interesting thought nonetheless, no?

 

You'd lose the manual mode as well. Might as well go with a TH350

 

Actually the titan redlines like at 6200 or 6300 something like that.

 

Actually the Titan has a manual shift mode function as well, it works the same way as the 350z's. lol Our Parts truck has a lever on the shifter column stalk that you can switch to manual mode.

 

really, i did not know that.
