Mythbuster...

Just for kicks, there's a rumor around that a 5.0 mustang transmission will fit the89' rx that I have.

I purchased my s5 dirt cheap, excellent condition however there are only two gears, reverse and 5th lol (go figure)
im planning to get the tii swap anywayz but i wanted to know whether or not that rumor is true,

Why bother? I never heard of a TII trans crapping out. It's not like you'll be using a 3 rotor.

And wouldn't you also need a custom driveshaft for the 'stang transmission?

New synchros + double clutching = you'll never ear about them again

Of course if your just cruising down the street double clutching probably isn't necessary.

Another problem. What clutch do you use? The T5 is cable actuated, not hydraulic.

Plus that adapter is $550, plus shipping. You can get like 3 TII trannys for that price. Or just have a TII trans built to spec.

Sure, almost any transaction can fit in the hatch area as long as you can lift it in there.

Double clutch downshift: press in clutch, put in neutral, let out clutch, blip throttle, press in clutch, select next lower gear, let out clutch

Rev match downshift: press in clutch, select gear, blip throttle, let out clutch

There's almost no point in double clutching, since syncros do the job of double clutching. Properly rev-matching downshifts will make your clutch and tranny last a long time.

double clutching . . . i'm not driving a peterbuilt . . . glad you where half kidding, should have been completely kidding though. Seriously, i've heard the 2nd gear syncros in TII trannys go.

There most certainly is a point. If you're autocrossing and downshift from 5.5K to 7K, there's a chance your synchros aren't going to be quick enough and you can explode the gear if you yank the stick hard enough. My roommate has gone through three(3) new transmissions on his WRX in the past 18 months because he won't listen about that fact.

As for going to pick up groceries, no, it really doesn't serve any point except for wearing your clutch instead of your synchros. Though honestly once you get used to doing it it's no more on your mind than regular shifting, and it's good to keep up the habit.

Edit: And for anyone that has ever had Vin Diesel's line "...Granny shiftin', not double-clutchin' like ya should" pop in their head any time this topic comes up--you didn't miss it, none of the actors double-clutched for the camera. Nor would the characters do it anyway for a drag race that consisted of nothing but upshifts; inertia works enough in favor of the synchros (rather than against) that there's not much danger at any sensible RPM.

^lol. When I saw the first F&F I was like WTF? you can double shift in a higher gear?

Anyway rev matching or double shifting, it's all useless. Heel-toe is what's important.

So this heel-toe technique that I read about, I tried this little thing, to me it seems more dangerous then just slowly letting out the clutch as you pull off the brake and transition to the gas. Maybe its just my big *** size 12 boots, or the aftermarket pedal covers I put on that make my pedals closer together... At any rate when I tried this stupid heel-toe thing I damn near ended up going to fast around the corner and going into oncoming traffic, maybe its just that I have never done this before, but it just seems to me that its easier to slowly let out the clutch and let the engine idle up on its own, then you are in prime range to smack the gas coming out of the corner anyway... dunno what you guys think about this mysterious thing that sounds more like a dance than a way of driving..
