Weird shift only on snow

[parentg6]

Here is another one
My 97 camry (v6) experienced shifting problems but only when there is a snow shower. The transmission seems to downshift from 4th to 3rd for only a fraction of a second and then from 3rd to 4th. It can happen once in a while. If the road is slippery or slushy, the problem does not occur UNLESS there is a snow shower. It doens'hty happen when the weather is rainy so I concluded it's not an electrical problem. Can't figure out what would be the problem and it drives me insane

That's the second thread that I posted onto this forum and nobody seems to be qualified enough to help me?

Is it possible my car is simply haunted by a snow ghost? If so, what is the solution? That would explain why noboby here can help me...

I drove two different company vehicles--2005 and 2006 Fords with 4.6 engines that would do the same thing. IF AND ONLY IF there was a snowfall dropping dry, fluffy snowflakes or the same type of snow being stirred up into the air by the traffic ahead, the car would occasionally miss and briefly lose power, which sometimes felt similar to the transmission being shifted between gears.

Supposedly the problem was a defective airbox that would warp and allow some snowflakes to get past the filter where a sharp-eyed sensor of some kind would proceed to screw things up.

May or may not be what is bugging your car, but I just wanted to let you know that snow ghosts aren't always at fault!

its such a bizarre problem that i cant even fathom to guess. the only thing i can think of is ice could be building up on the transmission's kick-down cable thus causing it to downshift briefly when not needed. maybe the cold temperature and moisture contribute to some buildup around the throttle body, but i would think the engine would be warm enough to melt anything before it sticks/freezes.

my suggestion is to check the tension on the kick-down cable from the throttlebody.
