Some of you may have seen the thread where I was building a 440 for my RamCharger, and swapping in a 4 speed at the same time.
Well after I got it all together and presentable, I realized pretty quickly that the NP435 that I bought used off of failbook, was total junk. It’s the absolute worst transmission I’ve ever attempted to drive. So instead of rebuilding it or buying another used one, I spent way too much money on this
Tremec TR4050 5 speed. Fully synchronized and 650 lb-ft capacity. I also opted for the short throw shifter.
Gear ratios are, (6.16) (3.11) (1.71) (1:1) (.76) (R 6.03)
There’s only one bell housing that will work for this transmission and the Mopar big block (Lakewood #15335) and you have to get the long input shaft in the transmission for it to work. It has the same bell housing bolt pattern as a NV4500.
I got it from Silver Sport Transmissions. They were completely out of these for a few months because of supply chain issues. The day they got some in, they swapped out the input shaft and shifter, and got it on a pallet on its way to my door.
Somewhere along the line of transport, a careless F’wad impaled the box with a fork lift. The clutch kit that was included sacrificed its own life to save the transmission. SST sent another clutch out same day.
Can’t wait to get it back together and row through the gears!
