I have a 2005 C230 Kompressor sedan with the semi-automatic transmission and 76K miles. The tranny has been acting strange lately with late shifts that are rough and also shifting out of gear while accelerating. The problem seems to be worse in the mornings when the engine and transmission are cold and the air temperature outside is cold. It has been jumping out of gear into neutral while accelerating, and in order to get the car into gear again, I have to stop, shift into park, then shift back into drive. Needless to say, this problem can be dangerous if the car pops out of gear while in traffic.

Has anyone else experienced this issue? If so, what was the problem and solution? Could the fluid be low, or is it something more serious? Any info would be appreciated!

Thanks

They are putting a new trans in my 02 C32 because of hard shifts and weird shifts. They dropped the pan and found shavings. Have them drop the pan or do a trans service.

Is your car under warranty? Mine is not, and I can't even begin to imagine how much it would cast to have them drop and service the tranny!

Around $300-500 for drop, inspection, new filter, new fluid. Around $700-900 for full flush. Around $1500-2000 for transmission rebuild. Fluid could be low. I suggest dealership inspection for $100 dollars to determine the cause of your problem. Could certainly be low fluid, and you should hope for that. Low fluid obviously means you have a leak somewhere. Most common leakage point is the electrical wiring harness to transmission. I recently had to replace my radiator, and do a full transmission flush due to internal radiator leak mixing coolant with transmission. Purchased everything myself through 3rd party providers, and did all the work myself for around $600 dollars. The 2005 has Behr radiator, and shouldn't have that issue. If something is found, and they quote an unreasonable price which is typically the case I suggest finding a good independent shop to do the work for half the price. If excessive shavings are found in the transmission pan rebuild of the transmission, or replacement is a must.
