The transmission on my L300 surges during acceleration and won't shift until high RPM's (>3K) are achieved. What could possibly be the problem?

It surges or pulses and goes way past 3000rpm before it shifts. Mostly when you get on it hard going up hill in 2nd gear.

After taking my L300 to GM it was discovered to have both catalytic converters clogged. Expensive!
