I've been riding around with a new transmission. A borg/warner world class t-5. What an absolutely enjoyable difference the 5 speed transmission makes over the old 3 speed. Feels like a completely different truck.
I've had the transmission for a couple years and just couldn't motivate myself to do the change, now looking back, I should kick myself for waiting. Would I do it again, in a HEARTBEAT.
Have to do some creative work on the shifter, but hopefully I will get that accomplished in the next few days.
