I have mercedesbenz c 280 and i checked it out this morning and i saw two codes pop uped first p0715 and p0128 i am wondering to know what those two codes are abou
-
2000 SLK 230. P0715. Tranny shifts properly until temperature reaches operating temp. Tranny then goes into limp mode. Had my Trans fluid changed at dealership 3000 mile ago. Car has 85000 miles. Checked 13 pin connector. It was dry. To change adapter, must fluid be drained? Have not changed any parts out yet.
-
Although the fluid was changed recently, check the fluid level and condition.
What do you mean with "adapter"? the control module?
-
i changed connector plate tcm and solenoids still in limp node. trans needs to br reprogrammed by dealer.

I have a ml320 Mercedes Benz it's having the code po715 on it I have a transmission leakege and when I start it up and put in drive or reverse it just revs any ideas ? I was thinking it's the TMC or ECM control module
-
I doubt there is a problem with the TCM or ECM. You should start by checking the transmission fluid level. Low transmission fluid could set the code cause the same symptoms.
-
I have an sl500 03 and just had the plate andsensor replaced but now it won't go into drive or reverse
-
I have a 04 CLk55 AMG with this code. I changed my plate. the input sensor did have a crack in it on the conductor plate. So the plate was a part of the problem i thought. but im still not shifting. the car runs and drives but wont shift. IDK what to do. I cant even find out where the turbine speed sensor is to change it out. So anyone know where it might be? I have cleared my codes but the P0715 still pops right back up. the car does a lil jerk shifting from drive to reverse and vice versa.
