My car driven normally will shift just fine but if shifting at 5500rpm+ from 1st to second it wont go in, like something is blocking it. What could this be, it just started a month or two ago.

 

what fluid are you running? I had that problem too when I had synthetic in there and now that I switched back to plain jane o'reilly brand, its shifting fine.

 

why would synthetic make it worse??? alot of people on this forum use it including me, with good results! well i use the prestone DOT 4

 

The T-56 is fine with synthetic. I ran synthetic with the 98 paper blocker rings and I still run it after my rebuild. (which I have to say the inside looked like it was in great condition, no usual wear despite having 80k miles.

As far as synthetics go, I find I have an easier time shifting with them in cold weather than I did with regular transmission fluid.

 

sorry forgot to say mine was built with the carbon fiber blocker syncros. atleast thats the same problem I was having and when I called my builder he said change to original b/c I probably glazed one.

 

I would use Mobil 1 ATF but we always use synthetic in ours even if a customer with a stock trans calls. If you are having the exact same issue as before I would start with bleeding the hydraulics and making sure that the clutch is working correctly. If you narrowed that down then changing the fluid to fresh Mobil 1 is what I would do.
