3.3l 2009 GC. Transmission slipping after few seconds driving from cold and back to normal few seconds later. Only when cold, after few seconds driving seems going on neutral. After put it back to neutral and back on drive, no more issue. Third time it happends to me this week. Anyone aware with selenoids packs replacement for such an issue ? Fluid and filter are new / fluid is completely clean.
I would start by checking the fluid level again. It’s possible that it’s a bit lower now that you’ve driven it a bit. Lower fluid pressure will certainly cause it to go to neutral.
