downshift seems abrupt - anyone else?

I have a 2012 TRD Sport with auto transmission. I noticed that when I touch the brakes while going downhill, the truck often downshifts hard. It makes me and my passenger (aka, wife) think I am stomping on the brakes and jerks us forwrad a bit.

Has anyone else experienced this and is there any remedy?

 

I know what you are talking about but wouldn't compare it to stomping the breaks. On a long downhill while off the gas from anything over 55, it seems to engine brake itself to slow down. I have heard that these trucks cut fuel to help but not exactly sure how that works. Either way, just slam on brakes every now and then to keep her in check lol.

Are you effected by the TSB ? http://www.pdf-archive.com/2012/01/06/tsb-0373-09/tsb-0373-09.pdf
beleive it or not , your truck is designed to save fuel when coasting . When you take your foot off the gas , the PCM tells the injectors to turn off . This is why your truck feels like its slowing down in comparison to older vehicles you have owned . Combine this with the converter remaining locked up and the transmission downshifting while going down hills can really be felt in the drivers seat .
