Tranny thump.

Hey guys,

Any thoughts on transmission shifts at low speed that hit with a "tonk" kinda sound and feel. It's very intermittent, once or twice a week.

Thanks

Jeff

Yeah, they're all good and it's too intermittent for a motor/tranny mount.

Maybe it is a software issue.

Do the RPM's jump during a shift?

Hi,
have you ever flushed transmission oil?I do it every few years and can say the oil on dipstick looks much better than the one coming out when draining.
