JIMMY STALLS AFTER 35 MPH

1988 GMC S15

Transmission problem
1988 GMC S15 V8 Four Wheel Drive Automatic 147000 miles

I RECENTLY PURCHACHED A 1988 JIMMY WITH A MOTOR AND TRANSMISSION FROM A 92' CAMARO ALREADY INSTALLED IN IT.I DON'T KNOW WHAT MUCH ABOUT THE MOTOR EXCEPT IT IS A V-6 AND THE TRANSMISSION IS AUTOMATIC. THE ENGINE RUNS GOOD AND HAS GIVEN NO PROBLEMS UNTIL NOW. WHEN THE ODOMETER REACHES 35 MPH THE TRANSMISSION STALLS. THE MOTOR REVS AND THE TRANSMISSION STOPS PULLING. WHEN THE SPEED DROPS BACK DOWN UNDER 35 IT HAVE PULLING POWER AGAIN. THE MOTOR RUNS FINE THROUGH THE WHOLE PROCESS. ANY IDEAS ON WHAT THE PROBLEM MIGHT BE? THANKS IN ADVANCE FOR YOUR HELP.
