Car has a rebuilt transmission. Will drive full speed, rpm's stay at 2500 or under. No check engine light. D4 light will not light up. Car runs and idles fine. No overheating or other issues. Has a poor battery, a little corroded that may need replacement. Going to try that first. Shifter will go into all gears and it acts like it is shifting but not sticking into fourth gear. I want to fix it and not sell for almost nothing as I feel it is probably a small issue but without codes I do not know where to start. I have been told everything from cleaning the shift solenoid to battery replacement to sensors. I cannot afford to randomly replace parts.
