My 2003 dodge caravan whines and when it seems

I would guess its not your transmission but your computor for your transmission have that checked !

The shift solenoids are usally located inside the transmission pan and yes this could be the cause of not shifting.I would try one thing first try shifting manually put the gear shifter in the number gear and take off as you begain to pick up speed shift the gears to the number two and so on and see if it shifts this way.Get back to me and let me know

my van is doing the same exact thing but the othe day it was perfectly fine no slipping i went about 25 miles and i started off from a stop the engine rev and tranny slipped and the van died i restarted the van it runs great but acts as if there is no transmisson does not take power frm ngine when shfted does nothing please help

have a tranny filter fuid change soon

sounds like you need a new clutch. is there anything unusual when operating the cultch or gear shift.

MOST LIKELY HAS A PLUGGED TRANSMISSION FILTER.
TORQUE CONVERTOR CLUTCH FAILURE COMMON.
CHANGE TRANSMISSION FILTER AND ROAD TEST.
IF NOISE IS GONE AND RUNS NORMALLY, CHANGE TORQUE CONVERTOR AND RESEAL TRANSMISSION.

Verify that your trans fluid is at the correct level. When if at all was the trans last serviced?

If fluid is low, try bringing it up to proper level with Valvoline ATF+4 fluid. You need to used either fluid from a dealer, or the valvoline brand which is approved by Dodge.

It sounds like the converter may be failing.

check the transmission fluid level - be sure - VERY SURE - not to over fill it as draining the oil is easy - draining the trans is way more expensive and you will kill it if left over full

BELIVE ME THIS HAPPENED TO ME AND IT WAS BECAUSE MY OIL WAS LOW CAUSING THE ENGINE TO REV HIGHER TO MAINTAIN SPEED.DO YOUR SELF A FAVOR AND CHECK (ALL) THE FLUIDS IN YOUR VAN 1'ST.HOPE THIS HELPS
