I recently had a JDM tranny installed in my 95 Accord 2.2L Automatic. Since it was done I swear my O/D is running about 300+ RPM higher on the freeway than it used to, and i'm almost certain that its engaging properly. Tranny was out of a 96' I think. Its really bugging me alot and milage will be going down the tube. Is there anything I can do to solve this without spending a ton of money?

Thanks!
