No, different gear ratios, not all are world class, many use gear oil.
Also, biggest difference is shifter is in different location. It's moved further ahead. This means the trans has a different tailhousing and shift rail setup.
There are many different versions of the T-5 out there. There is even a 4WD T-5 with a transfer case bolted where the tailhousing should be. Those came in 80's blazers.
