Most of the time that my car downshifts I feel a clunk or what I can best describe as a bump from the back. Like someone rear ended me lightly. I feel like that's not a good thing. Any ideas?

Could be a few things...
Low tranny fluid
needs to be flushed
Has water mixed in
I would say bring it in and have the dealer flush it. How many miles do you have on her?

 

[tmjchrysler]

Some had said maybe engine or tranny mounts, but I have about 88000mi on it. It happens when the RPM's get higher from acceleration and then I let off the gas completely to let the car downshift it self... Then it feels like someone rear-ended me or something close to that.

Could be mounts too. I know in my camaro I could just use a prybar and check to see how much play I had but I have not had that problem with my 300. I would def have the dealer flush the tranny anyway as it should be done every 60k.

 

[tmjchrysler]

I'll have to try that... Maybe I'll do that this weekend. Cause next week i have to do a long drive (800mi). I'll let you know how it goes. Thanks for the advice.

No problem goodluck and keep us posted!

I'm currently having the same issue. When I'm at a high speed and it down shifts sometimes its hard and like you said feels like you been in a fender bender. Ill have to get the fluid changed and see if that helps

Matt welcome to the fourm! I would give the same advice and say get the fluid flushed. How many miles do you have on your ride.

 

[matt300inSanAntoTX]

I just bought it has 92k miles on it. Not sure how the previous owner took care of it but it looks in very clean shape so far

 

[onesickhotrod]

That's good that it looks clean but its all about the upkeep! As posted before the tranny should be flushed every 60k and if its been driven hard its pry about due. Did you get an extended warrenty or have a lemon law there? Maybe you could get this done at no or low cost.

 

[matt300inSanAntoTX]

Yes, i did get an extended warranty and there is a lemon law here in my state, ill look into it more and see what i can do.

A few days ago my cars transmission started getting A lot worse it would let loose at random, it would be stuck in first gear and sometimes when it was up to running temp just disengage altogether and feel like it's in neutral in every gear. So I had my mechanic tow it to the shop. One of his mechanics said he thinks it is the transmission fluid filter he thinks it's cracked and air getting into the transmission. So if that is the case this part only about $30 - $40. I'll let you know when I get the car back how it goes.

Well I got the Car back from the shop and my transmission filter was cracked and was sucking air in. So at this point it's running well. It's running like a brand new car.

Glad to hear that was a simple fix!

 

[tmjchrysler]

Did not fix it

Today my tranny went out again i was slowing down for a red light I started hearing that whining sound that I did the first time this happened. then when the light went green I tried to drive forward but it felt like the car had half its power and would slip in and out of gear as I moved to the next red light. As the light 2nd light turned green it wouldn't go at all... I shut off the car and waited like 30 seconds then turned it back on, it still hesitated and felt like half the power. but I did make it the 3 blocks I needed to get to my driveway... any thoughts on what it might be?

Could be a number of things. Got to drop it out and have a look at her. Do you still have your warranty

 

[tmjchrysler]

No I don't have a warranty.

Update: sadly my transmission has gone out completely, which will forced me to sell it and buy a different vehicle. I may end up with a chevy silverado. So this is my good bye to the 300 forums community. Thanks for the memories.
