transmission trouble

[Paulomancha]

hi everyone
My name is Paulo and I just bought a 2005 saturn relay
when I did a test drive everything worked fine but when I took it home I start noticing some transmission troubles
if I press the gas to hard when start driving, the transmission shakes and then make a hard quick when engage then make another quick when engage on the next gear after that works fine
if I don't press the gas to hard when start driving it starts ok but still makes a quick on next gear.
can someone advise me what can be the consequences if I continue driving like that.

It would be easier for others to help if your description of the problem was developed more clearly. The highlighted and colored words are not clear as to their meaning and usage here, along with the odd sentence structure.

80 K mi. Relay and unhappy from day 1. Piece of ****.

Mine did that a few times when it started getting really cold outside. When I had it in for its oil change the mechanic said at 90k it calls for a trans fluid service. Might try that first. Dealership quoted me 180 for a transmission flush and filter exchange.
