Is there anything I can change to make them compatible ?
Transmission shop says they are compatible do you have any links to support your answer ?
Turns out the speed sensor plugs were crossed. I straightened them out now speedometer is working and its up shifting, but when it shift to 3rd the rpms go up and doesn't want to shift I let off the gas and it feels like it goes back into 2nd then pulls normal but I feel like the rpms are high around 2200rpm at 50mph. Could it be a shift solenoid stuck or not functioning or check ball stuck ?
