Hi everyone!

i just recently purchased a 2004 crossfire… w/118k miles, love the car…. I wanted to have the transmission oil changed since I didn’t know if it was ever done…. When I took the vehicle to a shop that was knowledgeable and certified to work on the car… they actually suggested if the car was not giving any trouble in switching gears, leaks..etc… that it may be best to leave it alone….. if the the oil was not changed, then changing it at this point may be more damaging since any particles of slugg may at this point dislodge and cause issues….
So I didnt have the work done….. both men appeared very knowledgeable, so I wanted to ask this to you all….. what are your thoughts?

They are probably right.
You can download the service manual and check out the transmission maintenance section.
Here's the link.
Manuals and other service info

 

Owner's manual specifies a transmission fluid and filter CHANGE, NOT A FLUSH, at 80,00 miles, with no further service nor even checking of fluid level. Some argue that a flush might dislodge debris accumulated into firm globs, which can then migrate to small control orifices, maybe jamb valves but a drain without flush likely allows these globs to remain in place., Cap of dipstick tube to be reinstalled. I DO NOT KNOW IF THIS CAP IS TO MAKE AN AIR-TIGHT SEAL WITH THE TUBE. Sealed-for-life automatic transmissions and hydrostatic drives are common these days. I have a sealed transmission on a hydrostat lawnmower going strong after 20-plus years of use.

 

I change my filter between 85 and 100 thousand miles ,, if i can i collect the fluid in the pan drain it through a
paint filter and put it back into the transmission I sometimes have to add 1 qt of transmission.
MOST transmissions do not work well with new fluid. after a filter change,, if u have too change the filter add the needed fluid
and drive. also use ONLY Mercedes transmission fluid (check for fluid used in slk320/ slk32/ c32 and c320)

 

Why are you quoting me/barking at me? I didn't ask the question.
I agreed with the mechanics that it was a good idea not to mess with the transmission. I suggested he refer to his owner's manual. He could also download a service manual from the link I posted.
Sealed for life, doesn't mean lasts for ever. The transmission fluid has to be checked and at some point will need to have some more added.
By the way, the cap is locked to keep regular people from checking their transmission fluid. This way Chrysler could charge a ton of money to do something that you could do yourself.
You can get an aftermarket dipstick and a replacement cap for less than $30.00.

 

My God, one cannot even offer a bit of help without raising hackles, retort, rebuttal. Oh, our "beautiful" MAGA America, where everyone is on edge 24/7.

 

Politics have nothing to do with it, however, since you brought it up, I was more on edge last year than I am now.
You addressed me in your "retort", and stated something I didn't say, I responded. Your response should have been towards the original poster.
I simply clarified what I had said and offered accurate information. I said nothing demeaning to you. You got your panties in a bunch over nothing.
