Well since I'm doing my diesel and 4x4 conversion I'm using the E40D. It will have a new 4x4 output shaft and new seals and gasket. It already has a new solenoid pack (2000) miles ago and a drilled valve body. Is there any other simple cheap up grades to do it make it shift a bit harder and have better mpg

 

other than an actual shift kit no

 

I've got a shift kit in my e4od. And I must say I do like it. Question for u thi I see in ur signature u say that ur lift pump is m.I.a and u have fuel pressure a 5.5 psi. How did u do that.
