I do not know how many miles you have on your vehicle, but most Jeeps require a fuel pump around 90k miles. Take it back to shop that installed transmission and inquire. A reputable shop will warranty their work for 12 months, 12,000 mikes. I had a similar problem on my 96 and a new fuel pump fixed it. The problem could also be a relay, but best advice is to check pump.
