Trans clunk

[L2C SRT]

i am having this problem when I slow down. It doesn't happen all the time but once in awhile when I am slowing down, it feels like someone hit me behind slightly.

I have this same issue, doesn't happen all the time and seems to happen "harder" when I'm braking from higher speeds quickly to a lower speed.

Do you think it's because the transmission is in the eco mode and has to change out of it quickly?

So are you guys saying the car jumps or pushes forward and you need to apply the breaks more to keep showing?

Have you ever noticed your tach when this happens?

I have the Corsa too and love it, my brother got his used from craigslist but I wanted a valid warranty so I got it here. Corsa Exhaust 14406, or you can try one of the sponsors here on the forum, they are allways having sales/specials. Either way its a great exhaust system, sounds great, and very easy to install.

You could be noticing the MDS dropping out and/or the fuel injection turning the fuel back on. The injection may (does?) kill fuel flow during prolonged, off-throttle deceleration and would need to turn it back on before the engine speed dropped back to idle. On my 6-speed, I can tell when the fuel shuts off and comes back on during deceleration...

Good thought...
