Auto Delayed and then No Engagement
I searched and read Auto Tranny pages. Some members posted similar issues but never the solution they ended up with. So here it is ...
2009 Cobalt LT - 4 speed automatic - currently only 58K on it.
Tranny Pan flush at 47K last year - filter not done.
Cold= delayed (3 sec.) engagement into D gear.
Warm = longer delayed (5 sec.) engagement into D gear.
Hot = no engagement into D gear. None of the forward gears engage. I put shifter in neutral - rev to
2000 rpm. and place in D about 1500 rpm with my foot on break - about 7 seconds later - it will
engage. Of course everyone else says I need to rebuilt tranny. I don't think so.
No check engine light. No codes via OBD2 reader. Always drives great once in Drive gear. Removed Pan today and changed fluid & filter - ensured fluid level. Still the same. In stumped and so is my mechanic.
