Hey all, Im buying a 2000 Olds Intrigue tomorrow for cheap because the dealer says it might need a new transmission. The symptoms are under hard acceleration it will revv up to about 4000 RPM's before shifting, but under normal operation it shifts fine. I pulled the dipstick and the transmission fluid was burnt and brown, of course needing a change. My question is, will a complete flush of the system fix it? TIA!
