Thread: UH OH I flushed the trans now i have a whine

Based on my expereince, your trans is shot, mine was doing a simular thing but along with the wine in park and neutral it was accompanied by a marble in a blender sound, eventually i lost all gears and it was nuked, rebuild my friend,

Did the trans make any whine noise before you changed the fluid and filter? I am guessing no based on what you said but you didnt say that it didnt make noise either. The only thing spinning when you put the shifter into any moving range such as R or D-3-2-1 is the torque converter and pump so that rules out anything else to cause a noise. If you stall the converter up will the whine get louder? Can you hear the noise driving or does it fade away? The TCC Stuck On code, P0742, is described on my Info page below in my sig and explains some of the causes. I would definately check fluid level again. How did the bottom of the pan look? Was there a lot of debris? Do you still have the old filter so you can cut it open and look inside? I can tell you from my customers experience as well as mine that P0742 is trouble and you are more than likely looking at a rebuild. The problem stems to the TCC solenoid being contaminated from debris in the trans. There is an exhaust port on the solenoid and when debris gets stuck in the solenoid it cannot exhuast the fluid well enough for TCC operation to be released or turned off, that is why the Stuck On code sets. Some guys replace the solenoid and get lucky for a while but the debris that cause the original solenoid to act up likely came from the torque converter and isnt going to go away on its own. Replacing the torque converter isnt the cure either as something internal of the trans caused the lockup clutch to wear in the first place and those problems need addressed as well and is often a combination of the valve body and channel plate inside the trans.
