It was fun while it lasted
2002 ML320, 2005 S430 4MATIC RIP, 2010 F150 Crew Cab
I'm wanting to change my transmission fluid, mainly because most everyone I have discussed this with says it should be done regardless of Mercedes' claims that the tranny on my ML 430 is maintainence free! Now I'm hearing from a few that it could cause the transmission to fail since the dirty fluid allows the transmission to have more friction to pull than with clean fluid. I have 128,000 miles on it and I'm experiencing no problems with the performance. But after seeing the fluid in my transfer case, I'd really like to change it before I take my next trip! Opinions please!! Has anyone had a failure after a fluid change?
