The speedometer problem and trans sound related to a bad vehicle speed sensor (VSS). AS far as the engine, has the check engine light come on? IT sounds like a throttle position sensor but I need a code to be sure. Also, check for vacuum leaks.
Let me know what you find.
PS: If the check engine light is on, have the computer scanned.
