Hi guys,
I need some help on this one. I been getting a rather weird problem lately.
I'm getting this problem while driving smoothly along the road then suddenly I will hear a LOUD LOUD LOUD BANG! Coming from under/rear...(dont know the exact place), as this happens I get a sudden LOSS OF POWER and I get really scared...

Then my natural reaction is to release the gas and push it back down again, and then it returns to normal.
I'm pretty sure I wasn't going over and bump or podholes on the road, as this had happened quite a few times. I'm actually guessing there might be something wrong with the transmission or something along the line.
What do you guys reckon? Thanx for helping out
Thanx for reading this,
Jack
