'99 E320 - Need help with transmission problem and preventative maintenance
Okay, so there was an issue with my E320 this weekend. My little brother has been using lately and he told me that the car had stopped accelerating while on the freeway. He had to pull over and make a complete stop in order to get the car working properly again.
He wasn't sure at what speed, but at some point he felt a jolt and the car began to slow down, though the engine kept running with the RPM at redline.
I hooked up my cheap OBD2 scanner and it gave me trouble "P0700 – Transmission control system -malfunction"
I'm not sure where to begin and need help from you guys, and this also leads me to my second question about preventative maintenance.
I have a '99 E320 with 137K miles and '97 E420 with 106K miles. Didn't have either for too long and I don't have any service records.
It's mostly been me doing short term and easy maintenance like oil, filter, coolant, brakes, etc., and fixing whatever my OBD2 scanner detected, but these cars are old and high mileage, and I don't want anyone getting stranded. We often drive through the mountains and desert where there's no cellphone signal, so it's very concerning...
Do you guys know of a resource, like service intervals, or adjustments to them now that these cars are old, and parts that at known to fail and should be replaced after certain miles/age?
Like the transmission fluid in this case I don't know if it's ever been replaced, it could be the cause of this issue and trouble code P0700...
