Hi,
I purchased my -00 Chrysler 300M about two months ago and the tranny gave up almost immediately at 120 000km, so I got the transmission replaced for a new "factory rebuilt" transmission at my local transmission shop. They used Mopar ATF+4 and the transmission went through the training process.
As I do not have any experience how a brand new 300M should feel and sound, I have a few questions:
- Transmission makes low-pitch "tractor-like" sound when engine/transmission is cold.
When I start the car in the morning or after workday (outdoor temperature is about 15-20 Celcius) and is set the transmission into "R"/"D"-position, the transmission makes low pitch, "tractor-like" sound for a minute or so when driving slowly. Is this normal, or should the transmission be silent right after starting the engine?
- Transmission seems to slip and engine feels powerless
Sometimes, when I drive the car in the city and make a turn, and the accelerate moderately back to 50km/h, it feels that the transmission is slipping for quite some time as the the engine revvs up and it feels powerless. At the same time fuel consumption skyrockets. It seems like the transmission stays at 3rd or 4th gear and slips quite heavily. Only way to get out this situation is to accelerate a little so that the transmission shifts to a smaller gear. This happens also when driving uphill at slow speed about 30-40 km/h.
- Transmission slips very badly or misses a gear
Sometimes, when I make a turn to a highway at 20-30km/h and make a very fast acceleration, the transmission makes a kickdown, the engine screams and revvs to 5000+ RPM in one second as if the gear would be in neutral or the gear wouldn't be not locked. After that the transmission seems the catch up and RPMs go back to 1500 range and the car accelerates okay.
Does anybody have similar experiences and/or suggestions what could cause these phenomena and what to do about them?
Thanks,
- Tim
