1993 eclipse bumps while hitting 10mph mark slowing down...?

[zeanimal2001]

Hey, when im slowing down and i hit the 10mph mark i feel a slight thump...i know there is a gear at 10mph because i hear it when i speed up... it doesnt do it in neautral...i was wondering if it was just the nature of my transmition or what?

Thanks alot! -matt-

What do you mean "there is a gear at 10mph"? Does it do it no matter what gear you slow down in?

[zeanimal2001]

well it usually does it when slowing down above 30mph...like if i go 15mph and slow down it wont...and if i go above 30mph in neutral and slow down it wont do it...When i speed up to 10mph the rpms go back down...like it switches gears...

Thanks,Matt


PS. Sorry for any confusion

Is this a manual or auto transmission? Also, if it's an auto like I'm thinking it is, why are you putting it in neutral when slowing down...or did you just do it once to test and see if it made the "thump"?

[zeanimal2001]

Yea its auto and yes i did it that once or twice just to confirm that it didnt do it...sorry about the confusion

Thanks,Matt

It's probably shifting down into first at about that speed then. Not really sure what would be wrong though or what would make it thump.
