5R55E problems

Hello
After my transmission gave up, I opened it and replaced the broken part. It was first clutch pack. The trans didn't move after that. I have other drum with all parts, but it is different than my. I changed the drum and the bellhousing. What you think? is it the problem?

When testing or diagnosing transmission problems, it is vital to first put a 0-300 psi gauge on the hydraulic test port and make sure the operating pressures are within spec. Without hyd. pressure, nothing works.
The first basic rule I follow when rebuilding automatic transmissions is this: all parts go back together EXACTLY as they where and in the EXACT same order as they where before the tear down. Now, if you have to replace a part, it has to be EXACTLY the same, and it may take quite some time comparing the two to make sure, especially if it is a good used replacement part, then re-check necessary clearances. DO NOT deviate from the way the factory had it, unless you really know WTF you are doing! When in doubt, examine, compare, test, and verify until all doubt is gone.
Lastly, the only thing I hate more than having to rebuild my automatic transmission, is having to take it back out of the vehicle and do it again because I made a mistake. Now, I have made mistakes, but I learn from them, fortunately I have have much great success rebuilding automatic transmissions. And lastly, NEVER give up when trying to solve a problem, do not let the transmission win!
