The transmission is in park. I haven't had any trouble with getting it in or out of park. I don't know if this is related or not, but the indicator on the dash doesn't exactly line up with what gear it is in.

Also, I moved the linkage to the middle hole today and moved the linkage about 1/8" back, and that did not make any difference. It is still close to the front. I read somewhere where it is close to the middle of the threads usually. Should I adjust it to the middle of the threads? The throttle linkage coming from the gas pedal is 3 1/2", so that seems to spec. The transmission still seems to be slipping when you hit the gas. It seems like it starts slipping instead of going in to the torque converter locking or going in to the next gear. It seems to do this no matter if it is in high, drive, or low. The transmission was rebuilt and installed in 2009, but sat from 2011 to 2021, due to previous owner being in bad health. It only has 500 miles on it at the most. I wonder if something could be sticking from sitting?
