Just picked up a sweet auto 91 dx, pretty much rust free!

The trans does something wierd, it doesnt really shift on time, sometimes way to early, sometimes late, but when you floor it, it downshifts after a second or two and than grabs and goes. So i dont think its 'slipping', but I dont know **** about autos!

Also, backside of valvecover, on left side (if your looking down) has 2 screws missing and some type of cap, im assuming some kind of sensor? but the car runs fine and no lights...
