I'm looking to install a transmission behind my 6bt (12v VE pump). I currently have the Tf727 that came with it.
My question is, how reliable is the 4l80e behind the Cummins? I'm aware that the swap should be straight forward, Summit Racing have all the necessary parts needed to complete the swap.
Should I rebuild the Tf727 or should I invest in the 4l80e swap?
Where I'm from, Dodge transmissions are virtually nonexistent (47rh/47re/48re), otherwise this would have been the preferred choice.
The truck will be used mainly for highway driving and I'm only looking to make 400-500 hp out of it. No towing or hard launching. Maybe a P pump swap later down the road.
Any input or feedback is highly appreciated.
