ok, i'm beginning to think i'm crazy here. but i swear it seems like my truck has a 5 spd Auto. According to toyotas website, you can't configure a truck with my specs (2012, reg cab 4x4, 4cyl) with a 5spd auto, just a 4spd.
this is what my shifter looks like in case you manual tranny guys aren't familiar.
as you can see, you can shift through the gears manually. "L" leaves it in 1st. "2" will let the truck shift on it's own between 1st and 2nd, but no higher, "3", same thing through the 1st 3 gears. now here's the thing, if i put it in "3" and rev it out (highway onramp acceleration) and then bump it over to "D" it will upshift once, the revs will hang for a second, and then they will drop again (5th gear??) If I leave it in "D" and am accelerating going up hill, it will "drop a gear" and the revs will jump about 500rpm, then if i keep on it, it will drop another gear to what i presume is "3" or 3rd gear and the revs will jump about 1500rpm. it's very slight, but a def noticeable 500rpm drop or climb when in "D".
here's a somewhat crappy video, road was bumpy and traffic so i couldn't accelerate too hard, but if you look close you can see 4 RPM drops (4 shifts equals 5 gears, yes?)
I wish there was time on the video to point out the shifts, but 1st one is at 20mph, second about 38mph, third about 46mph, and last about 48mph. the last one is just kind of a rev hang, but if i was accelerating harder the MPH difference would have been greater than 46-48
am i nuts?
