CLK270 gearbox

[Bruce John]

I have a CLK270 auto 03 reg and drove the car 120 miles to an airport and dropped off passengers. When I drove off the car would hardly go and not get above 2nd gear. I stopped, waited and tried again, same problem. I let the car cool a little and set off again. The car seemed OK then all drive was lost. I stopped, switched off the engine, restarted and drove off. The gears seemed to change then all drive was lost again. Twice when I restarted no gears would engage. After all the stops and starts I gave up and got a lift back for me and the car. There were no fault messages on the dash. Now the car is cold it seems OK but obviously it is not. I am scared to take the car out on any long trips. Does anyone have any ideas? Thanks Bruce

Get it on STAR and have the codes read.

Possibly the electro-plate playing up, possibly low ATF level.

See what others suggest

Could be an engine or a gearbox fault, need the codes read as already been said.

CLK270 fault codes

Yesterday I started a thread about gearbox problems on my 2003 CLK270 CDI Automatic that was failling to operate, disengaging while running, not changing up etc. I was told I needed to post the fault codes. I have been informd the faults are:

p2001 etc control modual faulty
p2315 can connection (a1 instrument cluster faulty)
p2600 curcit 87 voltage to low
p2221 signal of y3/6b1 or y3/6s1 implausable
p2500 transmisson has inpermissable transmisson ratio
p2502 gear impermissable or slipping
p220a y3/6n2-y3/6n3 speed comparison implausable

Does any one have an idea what might be the problem.
Thanks Bruce

Points towards a speed plate issue, but if it it losing drive altogether, it'd start by checking the oil level.

Where are you based?

Looks like a speed plate issue but also a low voltage fault code stored there, I would look at the crank voltage of the battery too, must be 9.6v to power up the ETC, you could have 2 faults there.
