Default AODE acting up...

Well, i've got a few problems with my AODE right now.

First off, shudder in overdrive is getting really bad, ive got the fluid flushed and tried additives but none work.

Second, for no reason when im crusing at around 55-65mph, the trans will downshift, im not pushing the pedal down more, just keeping it constant. i turned overdrive off, so the car was in 3rd, but after a few mroe minutes out of no where the car downshifted from 3rd to second while i was doing 55mph,

what is causing this to happen, the car has only 34k miles on it

Possibly a bad torque converter.

When you say you had it flushed, was it really "flushed" with the machine or was hte fluid just drained and changed? I've had a few occasions where someone thought that "flushing" was just another way of saying it was changed.

Yeah, in that case check the torque converter.

from what im guessing now it is the torque converter, as sometimes the car will stall out when i shift into reverse or if im turning at slow speeds

The torque converter is not going to cause the transmission to downshift on it's own. This trans is controled by a EPC or pressure control solenoid, 2 shift solenoids anda tccsolenoidfirst thing is to scan for any DTC's. The TPS tells the AODE or 4R70W trans when to shift, depending on where your foot is on the gas. Next make sure the MAP sensor is working right as this is the load senseing devise and if the engine thinks it's under load it's going to make the trans downshift, not a real common problem but i have seen it on some of the chryslers in the shop. The converter is not going to cause the stalling as your slowing down eighter, if the Torque converter clutch solenoid was sticking it would stall the engine hard right now just like someone turned off the key

He mentioned a shuddering issue, which is a sign of a bad converter. I'm also thinking that it's not actually downshifting and instead he is having problems similar to what you would see with stator clutch failure.
