Hello and welcome to JustAnswer!
P0700 sets in the engine controller when there is a code set in the trans controller. This one is just informational.
P0733 is a gear ratio error in third gear, P0734 is a ratio error in fourth gear. These codes set when the input and output speed sensor signals don't correlate for a given gear. This is either a speed sensor issue or the trans was actually slipping in these gears.
Di the speedometer drop out at any time?
When it attempts to shift into third gear does it freewheel and then drop into and stay in second?
