My 2003 jeep grand cherokee laredo (automatic)will not change from 3rd gear to 4th. When Im trying to enter the interstate, as I reach speeds of 60mph, the check engine light will blink and car will start jerking. Also the jeep will turn off when stuck in 5mph traffic. I feel this is all related. HELP?

We need the codes.

From your description, you have engine missfires that may require plugs and coils.

The trans is a separate issue. You need a trans shop to help you
