How to Replace and Re-Program the 7 Speed DCT Clutch Actuator - Hyundai and KIA Dual Clutch

[@Roscotech]

Just enough information here along with some written material to get this done without the special tools! I did purchase the tools to replace the clutch after an input shaft seal leak.contaminated the original. Got it all back together and couldn’t get it to relearn or even move at all. I had done a couple clutches in earlier Velosters but this one is different. I had already disassembled one half of the actuator and had to study it for a long time to get it back together (DONT DO THAT!!!). I was able to use a digital caliper and a small pick to adjust the rod length. Finally got it to relearn with my scanner and it drives like new!!! WOW! This was a challenge but it can be done!!!

Do you know how much you aligned it to?

[@shawnlichtmann977]

Wjat software do you need to re learn the touch point as I think that would help the rough shifting

[@AutomotiveDiagnosis]

Many scan tools cover this function

[@maynardbuzar]

what should be the mm legnth for dct 7 speed crdi rods? is it 71.5mm to 72.5mm?

[@AndysAverageAdventures]

If this is faulty would it stop the car from using its odd number gears?

[@zohaibkashif2656]

Yup

[@sathyavignesgopinath]

I have a Kia seltos 7DCT it’s run 50000kms now, my car is very jerky in 1st and 2 nd gear in stop go traffic , the service centre personnel is telling me it’s normal ,, it was not like that when it was new,, what should I do

[@BhavinPatel-k2c]

Ask him to check the wear and tear of the clutch plates.

Hello, I have a problem with 7dct, tucson nx4, car after an accident, damaged clutch actuator, I replaced it with the same one with the same numbers, but the car does not start, is any coding required when replacing?

[@djm9936]

This is the clutch slave Actuator? Is there another with its own reservoir? Mine has thrown a P090a fault code clutch actuator

[@TheMarto007]

Can I program the touch points of DCT without changing the clutches for improved performance, would this damage the transmission?

[@AutomotiveDiagnosis]

Shouldn't be any problem but it won't improve the performance.

[@TheMarto007]

@@AutomotiveDiagnosis thank you sir, keep up the good work

[@shawnlichtmann977]

Unlike zf or wet dct's where the clamping force is held by fluid pressure, this is held by a spring. The only way to increase clamping force is to put a stiffer spring on.

[@TheMarto007]

thanks for the insight. All and all I think it is not great design for a transmission. I am with this Tuscon for a year now, and would never buy something with dry or wet clutches, started looking at EVs, Lexus and German brands @@shawnlichtmann977

[@angelfernandez1102]

Hello, a question for you. To replace this part (clutch actuator) is it necessary to disassemble the entire transmission? It is exactly the same as your video.

[@andykelm2902]

no

[@initsuig83]

Ma si può sostituire lasciando la vecchia frizione?

[@AutomotiveDiagnosis]

Should be ok if part number is exactly the same, you also need to learn the new part.

[@leetos.4915]

Would the 2017 ioniq still run without this dual clutch actuator ? Mine is broken and I thought with engine actuator would be enough as single clutch to drive my ioniq

[@MrTherandomvidsguy]

Without that, you won't be able to move. And you'll def throw a bunch of codes. The actuator changes gears

[@ikzuq]

around how much money should this process take? I dont want to be overcharged and forced to try and fix myself to save the 7 grand they were charging me.

[@AutomotiveDiagnosis]

Price can be different based on the required parts, labour and country. You need to make sure what components they are going to change and check the price of them.

[@rebel5634]

can dct gearbox equipped in a car be replaced by AMT gearbox?

[@AutomotiveDiagnosis]

Hi there, it’s possible but you have to do some modifications to fit it in.

[@rebel5634]

@@AutomotiveDiagnosis why I am asking this is because I have purchased new DCT car recently. Got paint issue and recently serviced. Now it is giving jerks and autopark lock feature is not working. So I want to know if they have replaced my gearbox without my notice.

[@MrTherandomvidsguy]

​@@rebel5634 send it back someone did something. Let them replace it if it's under warranty

[@thurules]

@@rebel5634 was the issue resolved?

[@refaeljerebchevski3838]

Hello, when I shift into reverse I hear a faint clicking noise The vehicle after a gear update Is it normal? Only in reverse.

[@MrTherandomvidsguy]

DCTs are noisy transmissions. Clicking sounds when changing gears is normal. Mines does that and sometimes it just randomly clicks loud and does self checks. (Elantra N-line DCT)

Is this part available and what is the price please reply

[@ernestdamo677]

Nice video but please can't it be changed when you don't have the especial tool

[@AutomotiveDiagnosis]

Special tools are important what I’ve learnt in all these years is that for being a mechanic you need to have a sense of improvisation. Many times I haven’t had the tool so I had to make my own.

[@eduararoundtheworld889]

where to take the tools to adjust or calibrate dual clutch

Good one

[@don.timeless4993]

the worst gear ever. car manufacturer should use from now & on zf gears

[@thurules]

why worst?

[@don.timeless4993]

@@thurules dct are famous with snatching when complete stop then drive in traffic jam & snatching when gear down then gear up suddenly. those snatching happening because there is no TC (torque converter). those snatching causing clutch, oil & engine\transmission rubber mounts consumed fast. it also raise transmission temperature with light warning in traffic jam. buying a car that snatch is unpleasant driving & disappointing
