Replaced tps, and now it drives erratically. Hard downshift from 2-1, shifting from 1-2 occurs @ 21 mph, and 2-3 @ 36mph. Will not shift into od. BUT, on occasion, it drives fine. I have gotten trouble codes, 24, 15, 42, & 35

Hi doxchelse,

Thank you for the donation.
Here are description of the trouble codes.

Code 15 = Vehicle Speed signal. No distance sensor signal detected with road load conditions.

Code 24 = TPS voltage low or High. TPS sensor output less than minimum or more than maximum output. The TPS could have be installed wrongly or adjusted out of range.

Code 35 = Radiator Fan relay. Open or shorted condition detected in radiator fan circuit.

Code 42 = ASD relay circuit. Open or shorted condition detected in ASD relay circuit.
Code 42 = No ASD relay voltage sensed at SBEC. No ASD relay voltage sensed when ASD relay is energized.
Code 42 = Z1 voltage sense. No battery voltage sensed when ASD relay is energized.

Erase all codes and drive around till condition appears. Recheck trouble codes to see if all of them appears.
