the normal modern gearbox also every expensive to repair
and the term of expensive at here is how much?
The difference between a DCT and TCAT modern or not is the complexity of it as well as probability of it failing.
A TCAT if you maintain it by just changing the fluids and filter once a year or once every 2 years and for as long as you use proper fluids and don't tow anything heavy that transmission would rarely ever fail. If it fails then you are in deep shit as most modern ones are extremely expensive to fix as well as the main failure points tend to be the bearings and seals the next are the clutch packs or the solenoids, finally the part that is expensive will be the planetary gears inside the transmission. The problem comes where most people who own cars generally don't realize the symptoms of the gearbox failing at an early stage or some simply don't care and just carry on driving.
I've seen Peroduas with over 400,000km over 10 years old and still running on the same AT.
DCTs? There are several failure points for it, experiences from owning an Alfa Romeo with a TCT as well as a Ford with PowerShift, the Ford was under warranty for the entire time it was with us so no idea how much it would have cost to fix anything on it, it did need recalibration everytime the car was serviced or the shifts would be jerky, I was told the clutchpack and actuators does need to be replaced every so often.
The Alfa Romeo TCT has its origins in the infamous Selespeed single-clutch semi-automatic transmission. They are the pioneers in these types of clutchless manual transmissions which by the way isn't really as new as people think it is, this one when I had it was no longer under warranty and was basically a contra-account car, the transmission and turbo was having issues and yeah it proved to be costly to fix. First there was pressure pump and sensor, the pump cost RM1,800 and the sensor RM600, the second thing that needed replacement was the actuators, new one cost RM4,800 if you carried it yourself from Britain, then there was the solenoids, cost around RM1,800 per piece and each gear has one and finally there it is the clutch pack which cost RM3,000 for a rebuilt one and only available to you if you can carry the old pack to Britain to exchange, else you are looking at RM5,300 and finally there is the labor charge which cost me RM1,200 for that complete rebuild. I drove it a month and quickly flogged it off.
You can give yourself a 30% discount for that one by Geely and maybe you could extend the lifespan by 50% but eventually those wear and tear parts will need to be replaced. That Alfa was 4 years old and done 60,000km when I took it over. It started with leaky actuators, previous owner kept driving it till the pressure pump caused it to jam. I decided to give it a full overhaul as otherwise difficult to sell on. Thankfully a very pretty MILF bought it and I was happy it went to a good home.
