I got a 91 civic hatch original motor d15b1 & 4 speed. Was driving it one day and i notice the car cut off and the wheels locked up. Cut the car on and it was stuck in 3rd or 4th gear cant really tell but the shifter was still in neutral and unable to come out and go in any other gears. Any advice to fix this? I have a 92 civic with a d15b7 with a 5 speed. Will the trans bolt up and work to the 91?
