Concern after diff oil change

[willydoit]

Hi all,

after recent service by indie garage during which the diff oil was changed the car seems a little sluggish and I have noticed occasions when the car is not being held when in drive or reverse on an incline. Could this just be coincidence or could incorrect or low diff oil cause these issues?

car is 2006 with just under 46k miles.

Thanks in advance for any info

The diff oil wouldn't have any effect on whether the car holds or not, that's down to the transmission.

Concern with those symptoms is did they also change the transmission fluid and not put the correct Toyota specification fluid back in?

Thanks both for the input, as issue occurred over the weekend have not been able to discuss with the garage.  Will contact them today to check what was changed and with what.
