Customer Question

Hi Pearl!
JA: What is the model/year of your Mercedes?
Customer: It's 1999. We overhauled the automatic transmission and everything went well during the road test. The next day, it didn't shift properly. It stayed on a gear and the RPM went very high, between 5 and 6000 but the speed was less than 50 mph.
JA: How many miles are on the car? Is it the original transmission?
Customer: Around 110,000. It's the original one.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: We tried to add the ATF thinking that there wasn't enough oil but it's still the same.
