My name is shawn my rx7 would not rev over 4500 rpm threw out all my gears but will rev over 4500 in nuetral any help would b great

 

your transmission is a goner if your gears are poping out after 4500 , I was getting that same issue with my 5th gear .

rx7 transmissions are relatively cheap speak to FritzFlynn on the forums he may have a good one for sale , or you can risk getting a JDM one .

 

Hub springs and keys are worn. Tiny and simple parts. But requires the entire transmission to be disassembled.
