Just installed new starter and wont turn engine. when we jump the solonid and turn the key the engine sarts fine. 12 volts going to starter but just clicks when i turn key. Faulty starter?

 

Id tr and make sure all my grounds are clean and tight and if that dosent work id try replaceing the solonid i had same prob and fixed it by a loose ground on the startor and dirty ground on frame...

 

The truck started after cleaning the post and the starter relay. Now the truck wont go in to gear, we changed the tranmission (was the original Job) and have filled the trnny with fluid but wont go in to gear to move, really stumped now and I need this truck to be runnig, any help would be appriciated
