Volvo S40 problem

Hello friends. My name is Pablo and I am new. I hope to live up to you.
My problem is the following I have a used S40 volvo of 1997
recently bought for a few days to start every time I put 1st and reverse, when the clutch is released, it goes out to jump
as if it were the loose engine.Tho in speed is going well with a lijera bibration in the accelerator from 110kh.mi question is the following: Will any engine support be broken? or support for the box? And on the contrary, is the gearbox?
The engine tacos seem to be fine, those of the box do not know why I do not know where they are located. I would appreciate information from where they are located. Thank you friends

Good
if the motor tacos are well, you could have a problem in the press of the clutch that is deformed since I have understood it notice when leaving both in front and you
have noticed if you tremble the clutch pad ??????

Thanks for your answer. Not the clutch pedal does not tremble.
