1999 Mercedes Benz CLK320

Transmission problem
1999 Mercedes Benz CLK320 6 cyl Two Wheel Drive Automatic 117000 miles

I get the transmission controller error (P0700) when I plug in my tester; how much should this cost to fix (about)? The car runs GREAT, and there are no signs of slipping, missing, or grinding gears when driving (at ANY speed. Any LEGAL speed, of course. Yeah, that's what I meant.). I had to drop the tranny to replace the controller on my Jeep; can this be fixed in the 'Benz through the onboard computer (without wrenches)?

Also, the 'maintenance required now' light just came on (no P-code), and I need to know what to expect the dealer to do (oil/lube/plugs/coolant?), And how much to pay. I bought this car last week (from a private party; he'd only owned if for a few months), and I don't know what work has been done in the past five years (I got the older records). I'm a Nuclear Design Engineer (and shade-tree mechanic), but this is my first 'Benz; I wouldn't fall for the, ". You need to lube and rotate your thermal differentials.&Quot, but I probably wouldn't know if they didn't do what's expected, either.

Yeah, I expect to pay handsomely for Certified Technicians, but within reason (and I don't know what's reasonable).

Hi jamesclopton, Welcome to 2carpros and TY for the donation

DTC P0700

Your scanner is not enough to ID this code-What you need to do here is have the transmission control module scanned for code/s by the dealership to identify what's going on with the transmission probable causes could be internal leak, electrical connections internally,gear ratio and command valve/solenoids Dunno the costs involved here it varies with location. Also refer to P0700 below
