99 honda passport will not shift into third or forth gear, winter mode also does not work. is there a way to test the solenoids in the main case? would the shift solenoid 1-2/3-4 and 3-4 cause the possibility of a shifting issue. there arent any rattling noises, the tranny fluid was still red with minimal shavings on the magnet.

The transmission went out all of a sudden with no warning, so thats why i believe it could be electrical maybe the TCM or valve body. i would greatly appreciate some trouble shooting tips. thanks
