Actually it would be worse if they couldnt in the fist place
its really a novelty item or where every micro second counts

Sequential shifter would be great for the many who don't know how to drive a stick shift

No one said anything about a shifter turning a t5 into a DCT thats crazy talk.
Its a v8 box that weighs the same as an old stumpy L6 R30 but takes v8 torque.
No A15 will outlive it seq or not, its the fave car club box worldwide for solid reasons.
They are abused probably mostly by Irish Ford Escort rallye drivers behind crazy hp
even behind 650hp sierra turbo beasts and many fox bodied turbo mustangs to name a smidgen.

That shifter mod doesn't convert the T5 to DCT. It's still a single clutch with main and cluster shafts. And I'd be worried more about the dog teeth getting busted than the syncros needing regular replacement with its rapid gear changing.

I dont know DD if you like Datsuns lightweight simple design then....
1. DCT rwd BMW box is around 60-75kg all up
2. you also must welcome headaches from phantom issues ready to pop up from being a beginner at setting it all up with sensors all over the place.
3. Datsun folk like mechanically simple devices usually with less ecus the better for overall reliability.

In my case I really like this full mech setup that can be taken out with 4 bolts
much like the t5's bellhousing, front input shaft bearing holder/cover and shifter.

I have a recent painful experience with DCT gearboxes. My Ford 2.0L TDCi with a 6 speed powershift has developed an intermittent transmission fault. 3500 for a secondhand box, 5000 all up fitted (it's a big job), 13000 for a new box from Ford, 2500 for the mechatronic unit that's the likely fault. I'd be very cautious about any DCT based on this experience.

I decided I'd rather replace the car than fix it, the new family wagon is a VF SSV Sportwagon. Much more fun!

Anyone after a Ford that needs fixing?

T5 sequential shifter $2600 (does not include the gearbox)
BMW DCT gearbox ECU - $1500 stand alone kit is designed for BMW 7-speed DCT swaps into other cars. You can put the BMW DCT in basically any car, and the good thing is that you still have a usable clutch pedal, the transmission is treated like a sequential gearbox. You use the clutch pedal like a manual car to get the car going in 1st gear

Racers take note: The kit has no automatic mode

Cant imagine what the weight is as they are complicated auto box with ecu(s)
also to adapt and get all the sensors going would be a nightmare

I think the t5 is looking like childs play in comparison
Theres no cut and shutting or anything complicated

To my knowledge all DCT are electronically controlled (from the 1950s until the new 2019s). It's one gearbox with two complete manual gearsets inside. A clutch to disengage one gearset and another clutch to engage the next simultaneously. So it can go to the next gear insanely fast. All the car brands have offer them now, from Porsche to KIA to Ford. The GT-R has an Aisin with Borg-Warner DCT parts

Getrag DCTs are going cheap on eBay USA

DD that 2300 dollar seq paddle shift is computer controlled?
or full mech?

DVR I agree with you about H pattern art, I enjoy it but synchros
wont be an issue as they are so strong on a WC t5 and they are
cheap as chips, easier than any box to replace all parts.
A beautiful modular design inside and out, four bolts accessible
from the outside to remove box leaving bellhousing on the car
with fly, clutch and starter on same easer for install.
Rebuilds and removing front input shaft are a piece of cake
the things are like kids Leggo - This box is legendary

There was a NZ car with a cut and shut early escort T5 he used
for his race car as he was preferred not to destroy 60 series boxes.

It definitely would be a great option and modular setup that one
could as money budget allowed and skills maxed out allow one to
get excellent ratios cheaper than any box, use the H pattern with
a short shift kit a first and get to the best times on the track
then eventually get that extra second improvements with a seq kit.

If not still an awesome toy to have for something different that
is not in just a hyper car or high$$$ late race car but a datto.
