The Transmission Control Switch (TCS) is a momentary contact switch that is located on the end of the transmission control selector lever. Pushing the TCS will either disengage or engage the overdrive function of the transmission.
Are there any problems with the Tiptronic transmission?
Inherent Weaknesses. One of the few weaknesses inherent to the VW Tiptronic has already been addressed by the company. Early transmissions were subject to hard 1 to 2 up-shifts, erratic 3 to 4 shifting and torque converter shudder.
What’s the difference between semi automatic and tiptronic transmission?
It allows you upshift and downshift in that mode by using the gear lever or the paddles behind the steering wheel. It was developed with the idea of extracting the best performance from a vehicle. In contrast to the semi-automatics, the technology in Tiptronic transmission utilizes a torque converter instead of a clutch.
What is the solenoid number on a VW Tiptronic?
In a few known instances, an important solenoid designated “N89” has failed in the Tiptronic. The Tiptronic uses a number of solenoids in different combinations to engage the gears. First and Fourth gear share practically the same solenoid arrangement, except for the # N89.
What happens when you change gears in a VW Tiptronic?
If this solenoid sticks in the 3 to 4 gear change, it is possible to wind up in first gear instead of fourth. This will cause rapid deceleration, like slamming on the brakes, but so far has yet to actually damage a transmission. If you are thinking of running 911 power in your Passat, consider upgrading the stock clutches and and torque converter.
