I hate to post another transmission noise thread, but I have been searching for the past hour or so and cannot find another post that I can get any answers from.

I have a 2001, 2WD, 4.0 w/ auto trans that is making a crazy noise while accelerating in first gear. The best way I can describe it is sounding like an electric car taking off. Its a dull electronic sounding whine that I am only getting while in first gear. The transmission shifts fine and goes in and out of gear normally.

I just changed the fluid and filter earlier this week and just this morning I took off the transmission inspection cover to check the flex plate bolts. I was kind of hoping they would be loose, but they were fine. Is there anything else I can check?

 

Does anyone even have an idea that could possible point me in the right direction?

 

WOW! Thanks for all the help!

 

Could be air in the torque converter. May need more AT fluid. Mabe not. If you know that you put in the right amount give it a little while. Mine was making a similar sound and when I changed the fluid it took a few days for the noise to go away.

 

What type of fluid did you use?

 

Is it kinda like a straining sound? Do you have loss of power to the wheels? I have been dealing with this for a while and I think I am about to drop this tranny and take it in for a rebuild.....so frustrated!

 

I had no loss of power. Idk.

 

I have the same problem..i feel your pain..

 

I haven't noticed any loss in power. I really haven't noticed any differences at all besides the noise. I used Pennzoil ATF, it was the multi-purpose stuff that is recommended for the Dextron/Mercon that the manual specifies. I originally picked up the Chrysler specific 4+ (or whatever it was), but returned it after I realized it wasn't the right stuff.

The only thing that I can think is that there might be air in the torque converter like The Black said, but only because I believe the transmission was overfilled prior to me changing out the fluid. I'm thinking maybe I'll drain and refill again to try to help things out.

Thanks for chiming in. I was getting a little frustrated that it took a sarcastic remark on my part to get any answers...

 

I think that thats a good idea to drain and refill. Try to give it 3 or 4 days of driving to see if it clears up. As for not getting a quick response you have to remember that sometimes the people who have had or are having the same problem might not be viewing the forum when you first posted. And that your thread can quickly get moved off the front page where some people dont care to look. I always try to go back a little to see what was posted during the day that I might find interesting or that I might be of some help. Also sarcasum and Cherokee Forum don't mix to well. I could tell you were frustrated (as I have been also with my posts) but thats not why I answered. Hope that helps.
