i have a 2000 dx accord sedan. i placed this motor with a vtec ex motor. since i changed the motor and not the ecu, but i have the vtec controller onat 4700 rpms, when i shift from 1st to 2nd the tranny will cacth but then while in second the clucth will open and shift out of second automatically with out me doing any thing put cruise around 20-30. Happens when i am in 3rd too. Some one told me its the selinoid. Please help.

 

wtf mate? never heard of that one before, but it's definitely not normal...when does the tranny shift out of second automatically? is it the same rpm in both second and third?

 

yeah its crazy it pops out of second and thrid by its self and the rpms drop into nuetral. The shifter pops out and u can hear it going into nuetral

 

some one please help me

 

On a manual there isn't a solenoid that controls anything, it sounds llike you have an internal transmission issue. Not an electronic issue.
