My 94 Accord EX is shaking/vibrating when it is at the speed (2nd gear) of 15 MPH to 25 MPH. What seems to be wrong here?? Also, at the 1st gear the RPM goes up over 3 for just 5-10MPH???? Please help. Thanks in advance!

 

It might be broken engine mounts. I am going through that right now, and replacing them. It is expensive- around $300+ (parts +labor) to replace 2 engine mounts.

The tranny slipping...not sure but have you changed the tranny oil?
Might need some trans work...
