Speed sensor and neutral safety switch need to be checked and or replaced.

your transmission has a vacumn modulator on the side it requires vacumn from the engine to shift make sure the vacumn hose from the trans to the engine is plugged on and working, if that is correct then step 2 is the governer which would require a tranny shop to check, but id bet on the vacumn line give it a try! good luck and thankx billy

If I understand you correctly, you got a code error on the TPS (Throttle position sensor) If you can get a scanner hooked up to it, and push the gas pedal down slowely and then let off slowely you can watch it on the scanner. This will tell you if the sensor is not smooth, or has dead spots. You might want to start with this.

Hi, the late shift, and late overdrive issue may not be trans. related, if you need to feather the accelerator to achieve your shifts, and you have a late sift, or loss of power, you may have a restricted fuel filter. The lack of fuel volume can result in what feels like a trans. issue, but in actuality, you are starving the engine for fuel. I would check this first, as it is an easy, cheap possibility. Good luck...Coop
