#6 of 12 Transmission Problems by hukill300m Jan 23, 2008 (10:05 am)
The new one has lasted much longer than the factory one so that must be correct. I have also noticed my AM radio does not display the correct channel and occasionally the climate control goes plank for a few minutes. Nothing major, the transmission thing is my biggest concern right now. I have to pull over to the side of the road, stop for about 10 seconds and it shifts back into drive automatically. It seems like some sort of computer sensor (as I cross my fingers).
#7 of 12 Loose output shaft on transmission by 1566may Jan 27, 2008 (2:59 pm)
I have a 2000 chrysler 300m the transmission changes great does not slip etc but I have a clunking sound all the time I crawled under the car and found I had lot off movement where the half shaft goes on to the output shaft I replaced the halfshaft & the clunking is still there I have play on the output shaft. I spoke to a tranny shop & he said the whole tranny needs to come out & be rebuilt along with diferential as he says that is where my clunking is coming from   Is it possible to change the diff bearing without removing the tranny from the car ?
#8 of 12 transmission - electrical? by alcie Jan 29, 2008 (11:26 am)
on my 2000 300m with 79000 miles, the transmission sticks in second gear. I can tell, because if I shift to auto-stick that's where it stays. The speedometer stays at "0" and the RPM's go way up. This lasts a few miles, and then it works okay again. Once lasted 1/2 an hour, going 40 mph all the way home. I took it to a shop (not a dealer) and after several days of investigation, they say it is electronic - "the wires are all messed up/corroded". It works now, but no telling when it's going to give out again. have you ever seen these symptoms before? (btw - my car also displays the infamous "300m light show").

Replying to: alcie (Jan 29, 2008 11:26 am) I have had the same problem in the past with the speed sensor. My car would stay in second gear, my speedometer wouldnt move, and the car would turn off at high rpms. .. it was the speed sensor! now I am having problems.. I think it could be the tranny, I drive fine with any speed under 80miles an hour, then when I hit 80-85mph the engine light kicks in and the engine feels like it wants to stall shaking around...If any one can help me with some info of what might the problem be. thnx

Replying to: alcie (Jan 29, 2008 11:26 am) After reading through some of what has been posted I am convinced that Chrysler has a real problem on there hands.I own a 2004 last model of the 300M. It had 12K miles on it when I bought it. Very good at taking it in for updated services, etc. Last year "2007" is when I started having problems while it was still warrantee. Re-accuring problems with the surging of the engine as it shifts at even a low RPMs and then at 65 miles per hour, the RPMs would drop or go up. I also received an infamous 300M light show. Head lights/ dash lights flashing on and off day or night. Mostly when it was in the automatic switch mode. However the dome light also flashed on and off even when the lights were not on. and occasionally they will stay on. Another posting mentioned high alltitude might have played a part in the tranny problem. I also had more issues with higher climate areas as well. These problems have gone unsolvable by the dealer until the current visit to the dealer demanding to spend more time resolving this issue. I am currently having to rebuild the Transmission at $3200.00 and I have no warrantee to date. The lights still flicker, The engine has only 52,000.00 K miles on it. I am regreting the purchase of this car. and other unmentionables! L Replies to this message: alcie (Mar 27, 2008 2:34 pm)

Replying to: loli6 (Mar 26, 2008 8:40 pm) just to update the group - I finally took this into the dealer and told them I thought it was the sensor. They determined it was the wiring/computer, which was exactly what the original mechanic had told me. But the original mechanic couldn't fix it, being a computer. Chrysler dealer fixed it and I ended up paying around $600 for the deal, but now the car runs well. If only the hub caps/wheels didn't cause the tires to go flat (and the air conditioning fails even though I had it fixed 3 times in 3 months), I'd be a happy camper.
