I replaced my trans today it started ran I stopped at my house tried to start it nothing starter pretty new but there is a buzzing in my trans please help

 

Check your battery voltage............

 

It's fine battery showing 12

 

Are all your connections solid? My dads ground was a bit loose and it made the same exact noise.. Do a wiggle tests on your connections to and from the starter.. Also even if the grounds are tight, are the connections clean? Are they rusted? That could be an issue

 

Ok check battery voltage... You sadi 12 so then test while turning the key and see if it drops below 12, if it does then thats the problem.. You removed the starter to install the trans so check connectiosn there. Then check battery cables and make sure they are good and tight. The clicking is typical of a starter solenoid not engaging properly. It is possible thats bad too.. Just throwing out everything I can think of ....
