I just got a synthetic oil change and now the car is jumping when i shift gears not even 2 hours later?

This car(98 Grand Prix) is used and purchased 3 days ago and was not doing this until after the change.I just got a synthetic oil change and now the car is jumping when i shift gears not even 2 hours later?
Having the oil changed doesn't really affect the transmission. Since you just got the car, chances are the problem was always there. The problem with the car probably just comes and goes.





I had car where it would run great 1 week then run like crap the next week, then good again.





Wouldn't hurt checking the oil level though, which you should do after every oil change to make sure they didn't put in to much or nothing at all(it happens).I just got a synthetic oil change and now the car is jumping when i shift gears not even 2 hours later?
if you have only had the car for 3 days you cannot say that the problem was not pre existing. i see absolutely no link between going to a synthetic and a ';jumping'; condition try this pop the4 hood and double check the oil level and the transmission level, then look around and see if you can locate any wires or vacuum lines that are disconnected (usually around the air filter. either of the transmissions that come in that car are tried and true, and very reliable. get back to me if this does not resolve the problem.
CHECK YOUR OIL LEVEL





then bring the car back to the mechanics and ask them just to check it over for you. If they say they can't find anything they did wrong, take it to your mechanic, or a well qualified mechanic. Save all your reciepts. The important part is, let the company who did the oil change at least check it out (they will do it for free) and if they see something they messed up you have a good change they will bear the brunt of this. If not, you will have your reciepts showing you followed the right steps, JUST IN CASE you have to take this to court.





Dont worry though, there is probably a realllly simple and dumb thing that is causing your car to do that.








after that, if that';s not the case, it's
Adding synthetic for the first time I believe changed the attitude of your engine system which in turn would change the attitude of your tranny.
Changing the oil to synthetic will not do that you have another problem.
I don't trust synthetic oil. I would have stayed with the real thing.
