Is my transmission ok

I have been driving my wifes prius lately back and forth to work. The other day I drove my truck and noticed going down hills it felt like it was down shifting and lost speed. Did I just get used to driving the prius or could there be something wrong with my tranny?

By the way I have a 2010 TRD Sport stock w/ 270/70/17.

 

Most likely normal operation.

 

I concur, completely normal for this vehicle.

 

Normal, tho it does seem to be used in odd places and not all the time.

 

Thanks for the quick response.

 

i was wondering the same thing! my truck was doing it coming back down from the slopes in lake tahoe

 

I haven't read the specifics of how/when in the manual but I know coming down a steep hill if I quickly push the brake and let go the engine will kick down a gear and slow me down. This only happens if speed is gained after the brake touch. Also, I usually have to touch the brakes twice or three times for it to work.

 

This!

 

mine downshifts going down a hill too

 

Sometimes on steep declines it will downshift twice from top gear.

 

That's what happens when you drive a Prius. You forget how vehicles are supposed to perform.
