Hi, hope you can advise. I had a new trans put in approximately a year ago. I have a 190E 2.3 8V with 88,900. Just the last couple of days when I drive,it doesn't seem to know what gear to go into. It goes up and down then finally gets it right a proceeds. It is always sluggish on initial take off. I have been attempting to find out what to do to make it a little speeder. Any ideas on the stumbling? Thank you.
