Ok so I just swapped a d15b7 for a d16z6 in my 1995 civic automatic. I swapped the motor onto the origional trans because the trans had no problems. The swap went well, engine runs great. The problem is that the trans now shifts very poorly, the fluid is right and I had no previous problems. Do I need a different trans to match the engine? Any body have any suggestions? I also ran the wires for the vtec and im not sure if thats working. If it isnt working does that have an effect on the trans? Please help a rookie out. Thanks
