Number on transmission 45RFE
My car has an automatic transmission.

Hi there. According to the shifting charts to your transmission, third and fourth gear both use the Overdrive Clutch as a holder to get the gears with the Underdrive Clutch and the Fourth Clutch. Since your vehicle will only get 1st and 2nd gear and when it goes into 3rd gear is goes into neutral, then the Overdrive Clutch is burned our or not applying. I recommend having the transmission oil serviced along with a filter to see if anything changes. If the symptoms continue, then the transmission Overdrive Clutch needs replaced, which is inside the transmission. If you need further assistance with the transmission going into neutral when 3rd gear is applied, then seek out a professional, such as one from Your Mechanic, to help you.
