Transmission code P0700
 

Hello all. I have a 97 CRV and just replaced the Engine. during the installed I put the three plugs well on of them in the wrong place front of trans and was getting a hard fail code P0700 and the D4 blinking after relizing and fixing that I thought everything was fine. I drove down the road about a 1/2 mile and the check engine light comes on and the code appears again P0700.D4 blinking. I have check all the wire and everything seems fine. the car shifts a little hard until the D4 startes blinking then it operate normal. just wondering if anyone has see this. I have see some of the other post and ussally there is another code with this. I'm not sure how many miles are on this trans it is the second one and was put in the car before I bought it.one thing is the one plug is a little loose cant remember the correct name speed shaft sensor the one closes to the engine. Any help would be great
