I have to disagree with Jerry about the T5 only able use 5th on “pool table flat” roads, I can only use my T5 5th gear on downhills…..steep downhills, and at that point the speed is beyond my comfort zone….
My truck came with the T5, so I never had the original in this 46 (had them in my younger days on AD trucks though) I have to say the T5 is a sweet gearbox, it’s relatively quiet, and with a Hurst Blackjack short shift kit the rowing it is pretty easy, ratios are nicely spaced, I just dont use 5th….
