Snatch & Judder

[Alf59]

Wonder if anyone can advise? When the car changes up from 4th -5th gear (when in auto) it quite often (but not all the time) snatches the gear and then judders for about 1 second. Doesn't do it as much when changing up in manual mode but is still there a bit. Car has done 48K and wonder if a fluid change might help it or could it be something more sinister?

Any advice would be appreciated. Many thanks.

There have been some reported problems with the RX transmission (google Lexus RX transmission faults)

Wouldn't hurt to replace the fluid and filter but it could be a sticky shift solenoid or a software problem.

Could be worth having a code read for stored faults.

Thanks for your reply Steve. Will have the fluid & filter change done anyway and get a code read done. Have read a few (!) articles on the trans. faults and realize I'm not the only one. Kind of makes me feels better, but only kind of?

Thanks for your help.
