    42RLE Transmission Pressure range?

    I have a 2008 Jeep Wrangler JK Automatic and I want to improve the shifting. What can I do? Just edit shift rpm or what about the line pressure or maybe change the throttle percentage? My overdrive is really the problem. Under normal acceleration it shifts into overdrive at 40mph.
