i did a d16y8 swap into my 00 civic ex and got the engine started but my axles are spinning and my speedometer goes up and down like its idling from 0mph-25mph. does anyone know why that happens?? the engine is off a 96 civic ex and was orginally an automatic. also there is a lot of smoke coming out of my muffler. does anyone know why? im very stucked and need help really soonmy house is going to to get foreclosed and i need my car out of the garage asap. thanks in advance!

things i have done-Bleeded the clutch/changed oil and coolant/changed the automatic plate thing to flywheel/clutch.
