transmission gets stuck

I had the same issue on my 2006 CLK350 CAB. One trip to the dealership later, they fixed it under warranty...issue with a module that shifts gears (or something like that). Would have been a $2200USD repair otherwise. Hope this helps.

Bumping the gear shift leaver to left will cause the transmission to down shift and enter manual mode (bumping to the right up shifts). If you want to go back to automatic mode, Put it in neutral and then back to drive.

is your transmission fluid old ?? if yes change it as soon as possible All of it ( no top ups ) . old fluid can cause alot of big problems then this , or if your car has been driven more then 1,00,000 Km i think its time for u to replace the clutches or the belt inside it

i would suggest a fluid and filter change--sounds like the filter is plugged restricting flow

if the mileage is over 100,000 do not touch the filter or fluid, just add to it....however the computer module is the most common to go. always call the dealer and ask of open recalls, and most likely the service writer will assist you on common or quick fixes, not diag., but ideas.. let me know specifics, and i can help you further

Sometimes u need to wait & heat up the engine so the shifting would not affect the catalytic converter.....Delay only happens when first started !

Mine is doing the same thing. Only now when i cut off then back on it still stays stuck in first gear & rpms go up to about 3000 rpms & im only going 25 mph.

I was tolod there is a save mode to the transmission. If there is an issue, it will go to the save mode and not up shift. My wife's car lost a lot of fluid and it stayed in third gear, 60 mph at 4,000 rpms. She call me and I had her bump the shifter to the right which will by pass the save mode. She drove home about 70 miles. The next day there was a puddle of t. fluid on the garage floor. The mech was unable to find any problems. Flushed the cooler, and trans. Have to see if it does it again. The computer readout did not reveal any issues.

I had the same problem and the dealer said I had to replace a sensor for $2500 so I did. Two weeks later same problem and was told I needed to replace the transmission and torque converter for $7,000 including tax.

Have it done the maintenance like changing the fluid & the parts that needs to be changed ! I don't think the whole transmission has a problem ! I was having the same problems but i brought it to House of Imports dealership ! They did the proper maintenance w/c cost me close to $ 300.00 buck ! It's been 2 years since !

Try resetting your transmission there’s a button under your gas petal you reset it with car not running it also check fluid level don’t overfill they say it’s seAled I check mine myself need a trans fluid dipstick cost me $80 check when oil is hot

Che Clean your fluid level don’t need a mechanic check when hot don’t overfill add a bit At a time

Oil leak could be o ring on cooling line leaking oil is brown not red can fool you

13 prong housing has two o rings $25 dollar part or cooling line

The o ring costs about $5

The car sets transmission to driver the way they drive can reset its computer .tranny reset under gas pedal reset with engine not running

I just had total transmission replaced for $7,000 plus, less than two months ago. Now car is doing the same thing. Went to 4,000 rpm today in first before I could pull over and turn it off and on that resets it. Wouldnt go up driveway last week. Vibration under foot and slight grinding feel that was never there before. Help!
