Shift Kit or Sharadon Valve Body
 

Which would be best, I don't like how my 45rfe shifts. My tranny seems to have a lazy shifting problem.

What are the benefits of using the shift kit over the valve body?

Would either of these help with fuel mileage, (yes I know dakotas aren't known for good mileage) and I'm not hoping for like 2 or 3 mpg gains. But maybe like .5 or maybe 1 mpg gain.

Thanks in advance.

Don't bother with Transgo shift kit! They don't really do much for these electrinicly controlled boxes. I know, I fitted one to mine! Everything the Transgo kit tries do is automaticly compensated for by the ECU, so it ends up doing nothing.

Afterwards, I fitted a Sonnax line pressure booster which somehow dupes the ECU into doing what the Transgo kit wanted to do, and it REALLY makes a difference. Best of all, its a 5 minute job to fit OR remove.

Will it help with my lazy tranny shifting points?

Anyone else have any input on this?

i am just getting into my flashpaq but i have read and noticed that you can change shift points. the biggest mpg improver i have noticed so far has been taking off my mechanical fan, but i haven't had the programmer long enough.

sharadon stage 3 vb, top of the line for VB for the 45rfe.

Is the stage 3 practical for a daily driver?

all it does is firm shifting up a ton. if you dont mind it snapping into the next gear then yes its practical. they say the stage 3 isnt wife friendly.

Haha. I ain't married, yet. But I'm sure my lady wouldn't like it at all. Lol.

Would this valve body help pick my fuel milIeage?

it probably wont do a thing for mileage. i cant see how it would help or hurt either way.

do the sonnax and tmr mod first and see how you like that.
