If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.

Transmission is slow to engage in reverse or forward. It has a whining noise. Just bought truck it looks to have a reman trans in it, just replaced ecm. No check engine light.
After sitting for 24 months transmission delays shifting 2nd to 3rd.
My truck does exactly this. I put it in gear after it has been parked overnight and it takes a few seconds to engage in gear. I recently had my transmission replaced.
