Hello everyone,

1989 190E 2.6 just under 100K miles will not upshift from second to third gear. If I put the car into first, it will shift fine into second but not any higher. The RPMs will go to 4-5K and still no upshift from second to third. However, if I lift off the throttle COMPLETELY it will upshift. Then if I resume giving it throttle it will go back into second immediately. Any ideas?

Thanks
