So when it comes to the transmission on my 91 w124, I'm very hesitant to mess with it, but I really want to do a service to keep the trans as fresh as possible.

I called Mercedes Benz of Austin to see how much a transmission service would be and I was quoted $380.00, a bit put off by this I called Mercedes-Benz of Georgetown and asked about the same service, people seemed much nicer and really cool, they quoted me $320.00 and I'd get a loaner car, which I thought was pretty cool because I could run down to the nearest 711 and get a slurpee

I was hesitant to even change the fluid in fear that changing it would cause overall failure as what happened with my last w124 back in 2008, the transmission was running perfectly fine, changed the fluid and it failed a few days later... BUT what makes me feel a tad more comfortable is the PO had the paperwork for a transmission service a month before we got it, and she's been doing great ever since. Now he paid I think 275.00 for his service at some place back in Palm Springs and I've put almost 20,000 miles on the car since that last service, I want to keep this transmission going for as long as possible. There was a member on here, I think it was Hattie who said don't chance it and take it to the dealership because they have the proper measurement tools for this or something along those lines. I'm willing to pay, but I'm wondering if it's THAT bad of an idea....

What do y'all think?
