I have a 1995 Pontiac Bonneville with 247K. when the engine is cold it does not want to go into reverse until it has warmed up a bit other than that it seems to run pretty good. I recently had it tuned up.
By your description, this does not sound like an engine problem when you factor in your transmission. You may need to have your transmission fluid system flushed, and a new transmission filter installed. Also, you may need ot have your valve body and governor (if equipped) adjusted, cleaned, or replaced. You may have excessive metal chips from wear collected and settled when cold. As your transmission heats up and expands (flows freely) this may allow that debri to flow as well. Have your transmission serviced to see if this addresses your problem first.
I would look is at your transmission. Check for a leak. When the fluid is low, reverse is the first thing to go. If you do not have a good mechanic that you trust, check out the female friendly certified repair shops on the askpatty.com site in your area.

Check the fluid level in transmission - remember you check that when the engine is running. If it is full you need to go to a transmission place to have it checked out.

It sounds like you may have a transmission problem. The first thing I would do is check your transmission fluid level. Check your owner's manual to see how to do this. If it's full, then you'll need to have a technician properly diagnose your problem.
Most likely the tune up did not check out your transmission. Hope this helps.
