need new tranny

So my 3rd gear synchro finally went in my tranny so now i just kinda shift from 2nd-4th. I have a 02 so i have the 3650 tranny. I found a good deal on a t-45 from a 99gt. Any thoughts? Should i try and find a cheap 3650 or is a t-45 just as good? I know they both have issues, and i would need to get a new short shifter MGW FTMFW. Need some input guys. Also would it swap right into my GT?

nvm found good deal on a 3650
