SURGES AT 3RD GEAR SPEEDS (CUTS IN AND OUT)

1991 Jeep YJ

Transmission problem
1991 Jeep YJ 6 cyl Four Wheel Drive Automatic

i have a 91 jeep wrangler that a put a 94 4.3L vortec with the 4L60E tranny from an S10 blazer. Changed the jeep fuel pump to a new blazer pump. Runs good till I hit 3rd gear speeds and it act like it has a governor on it, it will cut out briefly than run again and keep doin it till I let off the gas. The speedo is not working do to a bad gear but I dont believe im even coming close to doing 50 mph when it happens. I NEED HELP!
