No probs and good luck
I had some butterflies when I backed out of the workshop for the first time after putting the 25T box in.. then painted some big lines and it was all good so I was happy
Mate of mine got a box for his GTS4, we got it to the shop to find it was full of water and the input shaft wouldn't budge cleaned it out, threw it in and it's still going strong behind a 530awhp 3L
Luck of the draw I guess it all boils down to!
