190E auto trans shifting ok?
 

:confused:Just purchased a '90 190E 2.6 auto trans. Well maintained, tight suspension, nice vehicle but concerned about the transmission and if it is shifting properly. My understanding is that it is a 4 speed and not sure it is going into 4th. RPM's are about 3k at 60 mph. RPM seems hi to me although all shifting is smooth. Your thoughts?
