Harsh Gear Shifts


ROJ

Recommended Posts

The tiptronic gearbox in my 2003 Hyundai shifts harshly into 3rd and sometimes jerks..

I found out that it is a commonly reported problem for early coupes to have this issue. The cause is a bad transmission control unit (TCU), basically the transmission computer needs to be replaced. I am hoping that I could reprogram the TCU rather than replacing it..

Did anyone experience a similar problem in their cars? And how did they get it arranged?

What you study is one theory, that may be specific to coupe.

But considering checking or changing the gear oil and gear filter, when you feel gears are jerky. Usually gear change is done at 40k -50k, if you dont have previous record its better worth the change than building the whole gear later.

I drained the oil a couple of months ago and filled with fresh one.. The gearbox runs very well but sometimes delays in shifting from 2nd to 3rd.. And there is a very light jerk that happens on occasions..

So far its running smoothly... Well it runs smoothly cuz i adjusted my driving habits based on how the tranny behaves..
