tarch at school said:you will need a custom bellhousing... and i am pretty sure the t45 is a bit better than the t5... since the t5 is used in the newer V6's
Joes95GT said:The T5Z should will work with a SOHC 4.6 if it works with a DOHC 4.6.I've seen it in a DOHC. The T5Z is perhaps a bit stronger than a regular T5 with it's 330 ft/lb rating. The only real difference is that you have a slower 1st gear (2.95 compared to the WC T5's 3.35).
I would think you mod motor guys would want the 3.35 first gear to make up for some lost torque....

Yes but the t-45's bellhousing is part of the tranny itself. You can't remove the bellhousing like you can on a T-5.tjm73 said:The tranny has nothing to do with bolting up. The bellhousing determines what bolts to what.

I agreed up until this point. You haven't seen too many busted T5's have you?Mustang5L5 said:The t-5 has an excellent synchro design, but it's weakness is strenght of gears.
I've seen one of these bust into pieces (literally!) launching on slicks. I can say with positivity that I (personally) would take a T5 any day of the week. T5's are time-tested-tough-as-nails tranmissions. Plus, they are a hell of a lot lighter than all other transmissions made by Ford.Mustang5L5 said:The T-3650 trans put in 01+ Mustangs is stronger than then both. It's rated at 360 ft-lbs and is stronger than the original TKO. This trans is tough, but it's weakness is it's synchros. Lots of issues on the 1-2 shift.
Joes95GT said:I agreed up until this point. You haven't seen too many busted T5's have you?They are weak BETWEEN the shafts. What I mean by that is the shafts separate, not allowing the gears to remain "together" anymore. I've also seen busted input shafts.
I'll have to disagree with that one. Inexpensive to manufacture for a wide variety of vehicles, smooth shifting and mass produced sure, but time tested…. Maybe after about a dozen updates over the years, but tough as nails…not even close.Joes95GT said:T5's are time-tested-tough-as-nails tranmission.

But now you have the issue of all this stuff in the chitty T5 case, which isn't that strong.Mustang5L5 said:Yes i have. I rebuild T-5's all the time.
3rd and the input shaft break all the time. The teeth shear right off on them.
The reason 3rd blows is due to the mainshaft deflecting. 3rd is located the farthest from any support. It's in the middle of the trans case. Under load, the forces on the gears try to push them apart. The teeth separate to their thinner points and eventually just shear right off.
G-force has an upgraded mainshaft designed to minimize deflection so that 3rd gear won't shear. They also have upgraded gearsets and input shafts.
I've seen T5's live much further beyond their "peak torque rating" than any other transmission. I've seen T-56's in Cobras (and Camaros, right?) blow to pieces. In one case, there was a cammed LS1 on slicks, he brought the revs up to 6700, side stepped the clutch, and that's all she wrote. I watched a Cobra this past Friday night at the race track pull second gear and the only thing you heard from there was gears rolling around in a case. This was on street tires, too.Gearbanger 101 said:I'll have to disagree with that one.

Yup, I've seen a few T-5's that have a had good luck too. I've also seen plent break including 2 at the track with nothing more than street radials and even one break under nothing more than a hard downshift. My father has been a Transmission Tech for the last 40-years and I've seen more than my fair share of T-5's work their way through his shop. The T-5 is a good tranny, but as a whole, not a tough one.Joes95GT said:But now you have the issue of all this stuff in the chitty T5 case, which isn't that strong.I've seen T5's live much further beyond their "peak torque rating" than any other transmission.

I learned to drive a stick shift with my car. I learned to power shift in my car. I couldn't even count how many WOT missed shifts I've had. I'm willing to bet that I've got 250+ WOT, 6000+ RPM powershifts on my stock T5. What does that prove to you? Well....nothing, really. It's my opinion based on my experiences.

Mustang5L5 said:G-force also has an upgraded T-5 case to take care of that problem as well.
The T-5 aftermarket is starting to come around. It's kinda the reason why i would rather stick T-5 than swap it out for a T45, t3650, tko500 or 600
