KA24DE wont turnover

I know this question comes up alot but here it is, just put in a used transmission and new clutch in, the car will crank but wont turn over.
It is a 95 altima 5 speed n e one with ideas, please drop one , Thanx

It started up fine when it went in the shop but wont start to get out, to save some money i took it too this local shop to get it fixed and the guy is goin back over his work but thought i would have a second opinion

so the engine was turning over before u put in the used tranny in?... what does it do when you try to start it? do you hear the started trying to do something with the fly wheel and it just seems like its jammed? possibly the clutch might have not been installed correctly so it wont let the flywheel turn over. Is it automatic or manual? because if its automatic and u just got that used tranny , something might be wrong with teh tranny and since the flywheel is connected to the torque converter it doesnt let torque converter turn over, and the converted is connected to the tranny shaft that goes inside the tranny so something might be wrong with the tranny and it doesnt let the flywheel spin. If its a manual then i honestly dont know what it could be with that, unless the slave cylinder is bad or the throw out bearing...

good luck

so it won't start up? try jumping the battery, maybe you never started it up for a while and killed the battery. Make sure your fuel line isn't pinched and your timing is correct. Good luck.
