Replaced the transmission cooler lines and now there is no reverse. Neutral moves forward like a spring or clutch plate is stuck. Runs through all the gears perfectly. Drive 1 seems to be slow to accelerate but when in regular drive first gear is fine. Thinking of draining the fluid again and flushing it out then refilling it. Not sure if some debris could have gotten in from the rusted out lines or if it sitting for a while may have caused something to stick. It’s a 2000 2 door and I don’t believe 4x4 has anything to do with it. Seems to work fine from 4x2 to 4x4 hi. I wasn’t sure if any old school tricks would work to try and free the clutch.
