T-56 problems
 

I have had work done on my 97 T-56 twice now and all together its cost me $3200, the last time it was gettting worked on, 2nd gear was stripped out. now im starting to hear some grinding when i shift hard into 4th, i know its the synchros but i dont want to get it rebuilt with oem parts, i want good parts that will handle more power. Anyone know where i can get some parts for a decent price. I also noticed when i put my tranny back in last time, in high rpms, the shifter shakes really bad. what could that be from?
